Does the Plastic Cap on a Presta Valve Serve Any Purpose Once Fitted to a Rim?

The cap keeps dirt and rocks away from the valve, particularly the fragile release mechanism. It's not the end of the world if the caps are missing, but I suggest leaving them on. They don't take that long to remove and replace.

I can see the use of the valve cap on a Presta valve when the tube is still packaged (it obviously stops the valve puncturing the tube), but does it do anything except look pretty (or not) once you've fitted the tube to a rim?

I've kept them on out of habit, because I've had problems with sticking Schrader valves in the past when I've lost the caps and dirt/grime has got in there - but the design of Presta valves suggests to me that they wouldn't suffer this fate.

Given that I really need to inflate tyres on a road bike every day, is replacing this cap something I can leave out of my daily chores?

Find Answers to the Hottest Questions About Valves
Here are top 10 questions about valves asked by people online.1. Low water pressure from Orbit valve.?Its possible the valve stem is corroded with stuff not letting it actuate properly open. Turn water off and unscrew the valve then actuate it electrically while watching for a full stroke. Make sure flow control is all the way open when inspecting valves stroke. Remember where you had it set when done or readjust. Also check the solenoid for corrosion and clean linkages. I would clean and coat with petroleum jelly. My guess is valve seat is gummed up so lube the stem and work it manually till it slides open and closed easy then test with the solenoid. Good luck!2. 1997 Honda Civic Hatch, Non VTec. Can you make it vtec?You can not just add a wire and have vtec, whoever is telling you that is either misinformed or has no idea how vtec works. The cylinder head, cams, valves, vtec solenoid and ecu are just some of the things that are different or missing from your car. 2006 was the first year they put vtec into every model civic.3. I have a 1997 Honda Prelude which has a Cylinder #1 Misfire. Any help?how many miles are on your prelude? the reason I ask is that honda has an exteded warranty on the 1997 models where the warranty on about anything that can cause the MIL to illuminate is covered for 15 years or 150,000 miles. if you have over the 150,000 then its out of that special warranty. my guess is that one of 5 possibilities exist. 1) if the valves are way out of adjustment you can get the misfire code on the one cylinder. valves on that car should be adjusted every 30k 2) a leaking fuel injector will cause the misfire in one cylinder and not in the other 3) a hung egr valve will often dump the air into the intake and affect only one cylinder. not sure which one it affects on the prelude but typically it will flood out one cylinder with too much air and not affect the others 4) a leaking intake manifold gasket around the #1 cylinder 5) real remote possibility would be a leaking head gasket around #1 probably a fuel injector if you've replaced the ignition components by the way, if the car does have under 150k and its in the US, put the old ignition stuff back on if you still have it as honda will pay to replace the cap, wires, plugs and to do an oil change one time betweek 75k and 150k on that car as part of the warranty extension. they wo not replace the parts if they are not the originals. hope that helps4. Where do I start with a Ring and Valve job?black smoke is too much fuel. if it was rings or valves, the smoke would be a bluish from the oil. if the thing sat for a while rings and valve stem seals would do that but since you say black, i think that your issue is carb related and not oil5. What diference would it make to a car? If one Piston wasnt working and the carbs arnt set nither the valves...?Try over and use spell check..... and decent grammar. If you can not express a question correctly how do you expect to hold a technician accountable for his recent work6. What is wrong? I can't get hot water out of my bathroom and kitchen faucets?Your hot water supply lines are likely plugged with rust or other sediment. Start with the faucet closest to the hot water heater. All faucets have a screen in them. Unscrew the very end of the faucet that contains the screen, to see if the screen is clogged. If it is, then either install a new screen, or else clean the old one. Next, check the hot water supply line to the faucet. It is often a metal or plastic hose connected to a copper pipe. Close the valve first, so that you do not make a mess. Then remove the hose, and run a coat hanger or something through it. That might be your problem right there. If it is clogged, remove the clog with the coat hanger or whatever. Then reattach it. If it is not clogged, then you have to work your way backwards through the plumbing, back to the hot water heater. Pay particular attention to any valves, because valves are more likely to clog faster and easier than pipes

Does This Exist? -Sliding Fluid Restrictor -Solenoid Valve -Ball Valve
What you are describing is a gate valve and you are correct in assuming that this would not cause foam. Unfortunately, I do not think that gate valves are manufactured in the small size that you need. If your tubing is 3/8" ID, that is approximately equal to schedule 40 1/4" nominal pipe size. I have never seen a gate valve smaller than 3/4" nominal pipe size.With that said, if I were trying to accomplish the task you describe, I would find a beer tap and attach a solenoid to the handleI am trying to come up with a way to restrict beer flow using a valve that does not cause foam. I have found that a solenoid valve causes a change in the direction the beer must flow and this sharp change through a different size opening creates foam quickly. I have thought about a ball valve or pinch valve but I need it to be electric, work very quickly and have a small form factor.Does anyone know if anything like what I created in this video exist? The idea would be electromagnets that cause the metal pieces to slide in one direction or the other opening and closing the flow of beer. The idea is keeping the opening in the valve the same diameter as the inner diameter of the tubing I would be using (3/8"). It would need to handle at most 14 psi and at least 12 psi. (Average beer lines are 9-10psi)·OTHER ANSWER:I am trying to come up with a way to restrict beer flow using a valve that does not cause foam.

Top 10 Questions About Valves Answered
Considering that valves may still be new to many people, we provide ten common questions and answers about valves for you to get started.1. What goes on threads first: tape or dope?I would use t-tape first and a small amount of pipe dope on the tape.I've worked on 30 inch water main breaks And have installed hundreds of copper water services with brass fittings,fire hydrants ive taped live water mains worked on cla- Val's installed 10" gate valves, PVC plumbing. Installed thousands of water meters and customer shut off valves. 15 years of plumbing outside of working for a water department for 10 years.2. is it easy to change shower valves?TURN OFF THE WATER SUPPLY TO YOUR HOME! Shower mixer valves have 3 or 4 ports on them. As you look at the front of the valve the port on the bottom is for a tub spout, it may or may not be there depending on manufacture. If you have a shower only you will need to cap this port and be sure to use a thread sealer. the port on the left is the hot water inlet, the port on the right is the cold water inlet. The port at the top is the out for the shower head. These will all be 1//2 inch threaded. Rather they are male or female will depend on manufacture. Depending on what type of pipe was used will determine your next steps. If the pipe is galvanized or copper line, you will need to sweat off the fittings with a torch, install the new mixer and sweat on the fittings. Be sure to disassemble the new mixer before applying heat to ensure you do no harm to the rubber seals inside the new mixer. Then reassemble the mixer and install the trims. If the pipe is Wersbo or PEX or plastic, you can simply cut the pipe and install the new mixer by using couplers. Be sure to use proper glue for the type of plastic pipe you have. If you have Wersbo or PEX a good plumbing supply company will have the proper tools you will need to complete your project. Be sure to check the cost of Wersbo tools if this is the type of plumbing you have because the tool are expensive and may determine if you are better off calling a plumber3. whats the best way to oil valves on a tuba ?The best oil when you are stuck with valve is machine oil. It is thin like water, odorless, and will keep the valve lubricated for a long time and it resists friction4. hot and cold valves under sink?i the water is dripping from the valve itself you need to tighten the nut on the valve next to the knob turn in clockwise. you wont need to turn it much. the valves are most likely are limed up that is why you could not turn the water off to the sink to change the supply valves turn of the main water supply to the house5. Do all Gas Valves snap open and closed?shut the gas valve to your oven/// does it snapor do you turn it with a wrench. newer ones you turn with your fingers .. no snap6. New Guidance Helps Clarify Use Of Domestic Air Admittance ValvesNew Guidance Helps Clarify Use Of Domestic Air Admittance Valves The BPF Pipes Group has just launched new guidance on domestic air admittance valves (AAV) for those working within the plumbing sector in the UK. The document provides clear advice on how to position air admittance valves correctly, as well as highlighting the different regulations currently in place across England, Wales, Scotland and Northern Ireland. Air admittance valves are used to ventilate soil and waste pipes so that waste water drains properly from a property. Without ventilation, air pressure changes inside the pipework due to the operation of domestic appliances would cause waste traps on those appliances to lose their water seals, creating unpleasant odours. Traditionally, open soil stacks have been positioned above the roofs of properties but can be damaged or accidentally covered, for example when extensions are built. Air admittance valves, positioned inside the roof space, provide a more aesthetically attractive alternative to open stacks whilst providing the same level of ventilation. The BPF Pipes Group document provides a detailed guide to the current regulations on soil stacks and air admittance valves, as well as operation, ventilation, capacity, ratings and location. A building control checklist is also provided to help those installing such devices in domestic properties. Steve Skeldon is Chair of the BPF Pipes Group's working group on soil and waste, and he commented: "Air admittance valves have been in use for over 40 years and provide a functional and more aesthetically pleasing alternative to open soil stacks, as they are positioned inside roof voids. We want this new guidance to provide a definitive aid to those working in plumbing and venting drainage systems for both new build and refurbishment projects."

The Hottest Questions About Valves
Do you want to know about valves? Here are some frequently asked questions.1. Afraid to crank engine - how can I tell if my cylinders are flooded with water?Given that there are no sensors inside the cylinders, I can not think of any way of doing so, other than Mauro's suggestion of removing the plugs and turning it over, which would spurt out any water in them.You could try leaving it to evaporate, but if any cylinders are sitting with both sets of valves shut, any water in those pots wo not evaporate off, so you would have to turn the engine over part of a turn (by hand) to cover all of them2. Does mitral valve prolapse show on an EKG?Mitral valve prolapse (MVP) is most often found during a routine physical exam when your doctor uses a stethoscope to listen to your heart. Your doctor listens for a certain "click" and/or murmur. Stretched valve flaps, as seen in MVP, can make a clicking sound as they shut. If the valve is leaking blood back into the atrium, a murmur or whooshing sound can often be heard. However, these abnormal heart sounds may come and go, so they may not be heard at the time of an exam, even if you have MVP. As a result, diagnostic tests and procedures may also be needed to diagnose MVP. An echocardiogram is the most useful test for diagnosing MVP. This test uses sound waves to create a moving picture of your heart. An echocardiogram provides information about the size and shape of your heart and how well your heart chambers and valves are functioning. The test also can identify areas of poor blood flow to the heart, areas of heart muscle that are not contracting normally, and previous injury to the heart muscle caused by poor blood flow. The echocardiogram is a painless test that's used to look for prolapse of the mitral valve flaps and for backflow (regurgitation) of blood through the leaky valve. Other tests that can help diagnose MVP are: A chest x ray, which is used to look for fluid in your lungs or to see if your heart is enlarged. An EKG (electrocardiogram), which charts the electrical activity of your heart. The EKG can show abnormal heartbeats, damage to the heart muscle, and enlargement of the heart. Only the echocardiogram is the most useful test for diagnosing MVP. Take care always!3. Is intake manifold gasket part of engine or valves?Wow! They are rip off artists, are not they? Of course it's part of the engine. Proof wo not work - you are dealing with a ripoff artist4. When would I use aluminum components (gate valves etc..) in a vacuum chamber over stainless or vice versa?Since it is a vacuum process I would give the highest consideration to a tight shutoff valve. Butterfly, and gate valves in particular, are prone to leakage but, given the size you may not have another choice. If you just want shutoff, I would use a ball valve, but 8" is a little bit large, and heavy. Since it is a vacuum process, no large flows are involved and a much smaller should do. Membrane or diaphragm valves have a very good shutoff, too. As far as aluminum or steel, given the pressures and if non corrosive chemicals are involved, aluminum should be more than adequate. . If youd also like to control the flow, a v-notch ball valve would be advised. In that case youd not need a full bore 8" valve, but a much smaller one. .5. Can I learn how to fix motors through books, or should I have someone teach me?You can always learn something from a book. How much will depend upon you.... Certainly the operational concepts of how a motor works is already available in many publications. Understanding these fundamentals will aid you in the diagnosis (trouble shooting) of a motor. How will you determine what is wrong if you do not know how its supposed to work? You can also (read) learn how to identify parts of a motor and there function. (Starter, Water Pump, valves , pistons, ECM) Understanding the fundamentals of how an engine and its individual components work together is the basis of developing sound diagnostic skills. Having good diagnostic skills is required to effectively repair a motor. You do not want to be a hit or miss mechanic randomly replacing items hoping to get it right, do you? The complexity of the repair is also a factor as to weather or not you would be able to just "read about it". For example changing spark plugs compared to replacing a starter or water pump compared to performing a valve job. Each type of repair has its own set of complexities some of which are not necessarily documented in a procedure as it is assumed the mechanic has some experience. Experience is a great teacher and compliments the book information. Start swinging wrenches on small simple tasks and you will gain experience and confidence to tackle the larger more complex tasks.

10 Most Commonly Asked Questions About Valves
Considering that valves may still be new to many people, we provide ten common questions and answers about valves for you to get started.1. the doc told me i have 4 valves leaking !how and what do i do?I think what it means is that some leakage is common, but the more the pressure increases, the higher the risk of more complications. Do as he says, and you will be OK. Good luck2. CB750. Carbs good Plugs good. Fuel good. Points good. Adjusted Valves (0.002 intake; 0.003 exhaust. Wont startMay need to replace the plug wires, check the coil, check the timing, replace the fuel3. Why do Democrats want to tax luxuries like pacemakers, stents, artificial heart valves, defibrillators,......?The democrats would tax you on your soul if they could. And they would use it to fund abortions overseas4. Installing new kitchen faucet/shut off valves?Double Shut Off Valve Dishwasher5. What Causes Valves to go out of Spec?For valve clearances to change the position of the valve with the respect to the rockers much change. Here is a list of some of the main causes of valve clearance changes: Half Ring Squish Closer shim deformation (where the half rings seat) Valve Seat wear (worsened by valve guide wear) Head wear (where valves seat into the head) Rocker Arm wear Cam wear My experience has seen the valve clearance changes to decrease as the miles increase, if the valves are set properly. The valve adjustment within the first 6,000/7500 and 12,000/15,000 miles are the most important ones to do. Excessive clearance begets more excessive clearance as the valves get hammered (closers). The openers will tighten up and you want to avoid interference (negative opener clearance). From what I am hearing the newer bikes have better materials and closer tolerances so the valves seem to stay within spec longer. Of course the higher revving bikes (track/race) need valve checks more often. Mike6.

We look forward to seeing you in Shanghai New International Expo Centre (SNIEC), 2345 Long Yang Road, Pudong Area, Shanghai, 201204, China7. valve tap that goes away?you sure if its valves or lifters? valves will cause a lot more problems than just a "tap". lifters on the other hand will cause a noise but usually no major damage if its just a tap. lifters in a modern engine are pressurized with engine oil to fill the clearance between the lifters and the camshaft to ensure proper valve opening. if the lifter has a clogged oil port then no or little oil can enter the lifter, causing a gap between the lifter and camshaft. even a small gap will cause a noticeable noise, especially when the oil is cold and thick at start up. its a saturn so its most likely an overhead cam setup, try a high quality oil treatment and a little thicker oil. if it keeps happening then listen to the lower half of the engine. if its louder down there then you have more problems than valves8. Are valves connected to tbe whole rocker arm assembly?I am guessing you mean will the valves come out if you remove the rocker assy. The answer to that question is no. The valves are retained by little half-moon clips that are wedged in a slot in the valve stems. The force of the valve springs against the top valve washer keeps them in place while also preventing the washer from sliding up past the top of the stem. You can remove the rocker assy without having the valves drop into the cylinders. You will have to adjust the gap between the cam lobes and the rockers when reinstalling so it is not like you can just bolt it back on

Blue smoke in cold starts and heavy acceleration after being stuck in traffic are typical symptoms. Worn piston rings produce blue smoke as long as the engine is running (it does not seem to be the case). If your car is rather new (under 100,000-120,000 miles depending on vehicle care and quality), that repair can be done without removing engine head. Compressed air is used instead to lock valves in place. You can search for a good mechanic or try to do it yourself. There is plenty of information in the web about how to do it. Good luck.3. i have 2 lines run thru my house for water each 1 has a valve on it when i shut 1 off i have hot and cold wate?I am not sure I fully understand your situation. You should have one water supply line that comes into your house. There should be a shut off valve near where it comes into the house. At some point, that line will split into two lines -- one will go through the water heater (hot) and will go to the sinks, tub, dishwasher, washer, etc.; the second line will carry cold water to the sinks, tub, toilet, washer, etc. There should be a shut off valve coming out of the water heater, as well as shut off valves for hot and cold at every fixture. Are you sure that the valves are "on" or "off" when you think they are? Sometimes, it is hard to tell just by turning the valve if it is off or on. And you cannot always go by the direction that you turn the valve, as they can be put in backwards and turn in the opposite direction than what you think. In your situation, I would just leave the valves set so that I have both hot and cold water regardless of whether you think they are "on" or "off." I am obviously not a plumber. I have rehabbed houses for 40 years & know that stuff does not always work like we expect it to.4. Are Angelfish fry compatible with Angelfish eggs?It is remotely possible for a little while. But your month old fry should be able to out-hustle the wigglers for food. I fear very few of them will make it. My angels comfortably spawned in 20-gallon tanks and did an initial good job with the wigglers. However I had lots of trouble raising up the fry. Looking back, part of my problem was not feeding the bbs (baby brine shrimp) within hours of when they hatched. It turns out that bbs, hatching in a day at 80 F or two days at 70ish, will go through two instars (or molts) in their first day or two. They are then double the size of newly hatched bbs and have a lot less nutritional value because they have used up the yolk from the brine shrimp eggs. So we need to hatch enough bbs so that our fry have little bulgy tummies. But we do not want bbs rotting on the tank bottom. Also we need to be able to have a couple of hatches going at a time. Cheapskate that I am, I use two or three empty/well rinsed gallon wide-mouthed pickle/condiment jars. Air was supplied by lengths of that hard airline tubing. Controlled by valves. they fed a lot of oxygen to the jat & were pretty easy to clean out under a hot water faucet in the laundry room. A friend of mine in the Greater Chicago Cichlid Association pointed out the space issue when he suggested using a 55-gallon tank for one batch of fry if they were going to grow properly. Occasionally one will see angelfish at aquarium club auctions with missing or miss-shaped gill plates. That is evidence of crowding when they were growing up. Do not buy them. There are 40-gallon tanks with the same "footprint" as the standard 55s. But you would probably want to do more than one 50% partial water change a week. As I type this, I can look across the living room at a planted 55 with a baker's dozen largish killifish (Fundulopanchax gardneri Innidere). Occasionally a pair is snagged out and sent to a fish show. They often place. Almost all of us who aspire to raise up fry struggle with giving both our adults and the youngsters sufficient space. And I am still learning. When someone considers setting up fish for spawning, virtually all of us must consider how we are going to give them enough room, how well we can feed them and how often we can do those partial water changes. Hope all of those eventually work out well for you.

Considering that valves may still be new to many people, we provide ten common questions and answers about valves for you to get started.1. Pool Equipment Life Span (Part 2)Part 2: This post will focus on the pool filter and finish up the last main item of the equipment pad. Later I will discuss the life spans of ancillary pool equipment like heaters, timers, valves, and automation. Pool Filters Most residential pool filters are pressure vessels designed to handle water pressure and house filtering elements to clean your pool water. Yes, I know a few of you out there still have in deck suction side DE filters but those are very rare at this point. Anyway, your filter housing sometimes called the "filter tank body," should last at least 10 years unless your pool equipment gets an inordinate amount of sunlight which can warp and weaken modern plastic pool filter housings. With proper preventative maintenance, the non wear out parts of a filter should last between 5-10 years as well- these include the band clamps, the internal grids, and plumbing including valves. The wear out parts- O rings, gauges, air relief systems, and Cartridge filter elements all need to be checked annually. Safety It is vital to make sure your air relief system works properly - this is a big safety issue. Pool Filters are designed to handle water pressure, water does not compress. They are not made to handle air pressure- air compresses very well and can build up to pressures no pool system is designed for. If you forget to bleed off the air after you clean your filter, this can cause a dangerous situation if your filter's internal air bleed off and pressure relief valves are not intact and properly functioning. Please get a licensed pool professional to make sure yours is and never open a pool filter with the system and until you have opened the pressure relief valve and are sure the system is not under pressure. Never let inexperienced people perform this task. Sorry off topic on my safety soapbox. Okay, so we know the useful life spans of the Pool Pump and Pool Motor (part 1) and the Pool Filter.

Consolidated 1700 Series Maxiflow® Safety Valves - How SAFE is SAFEConsolidated safety valves have been the industry leader since 1879. The Consolidated Maxiflow 1700 series valve continues to be synonymous with the protection of life and property from boiler over pressurization. With set pressures ranging to 5360 psig (369 bar) and temperatures up to 1120F (604C), this workhorse safety valve is installed on the majority of power generating stations worldwide. There is little doubt that the Consolidated Maxiflow was built for safety and to indeed protect both life and property, in that order. With a valve of this sophistication, the question now is how to ensure that improper maintenance does not diminish the functionality of this outstanding valve. Indeed, GE (Dresser, Inc.) goes to great lengths to extensively train and certify qualified Green Tag Center (GTC) service valve technicians in the intricacies of the Maxiflow and the various internal adjustments that must be made. Unique design features of the Maxiflow 1700 series valve assure maximum relieving capacities, adjustable lift, stable set pressures, accurate and repeatable blowdown (one of the shortest in the industry), and consistent seat tightness often exceeding 95% of set pressure. Each of these features provide benefits to the user in terms of closer operating pressure (narrow operating gap), shorter blowdown (closing pressure), and fine-tuned capacities (adjustable lift) to prevent chatter. Unfortunately, misadjustment of even one of these unique settings can have disastrous consequences. Seat tightness is the hallmark of the Maxiflow and is accomplished by utilizing a highly engineered THERMODISC in conjunction with a special DISC COLLAR. The Thermodisc has a flexible lip seat area that allows for temperature equalization and the use of system pressure to assist in achieving a leak tight seal. Control of the amount of disc tilt is accomplished by the Maxiflow's unique disc collar. Careful adjustment of this part (per factory specifications) ensures proper valve performance, while improper adjustment will result in seat leakage and the destruction of the critical Thermodisc. Too much disc "rock"(play/wiggle) and disc misalignment can occur; too little and the disc assembly becomes rigid and loses its ability to perform. The most critical function of any safety valve is to open at the appropriate set pressure and to relieve its required capacity (at full lift) to prevent system overpressure. Valves must not relieve significantly more capacity than is required or the valve will chatter and suffer significant mechanical damage or worse. The Maxiflow has the feature to allow for actually reducing the rated capacity in a given valve by RESTRICTING THE LIFT as allowed by ASME code. This is especially useful when a selected valve has significantly more capacity than is needed and a smaller valve will not work. The adjustment that controls the restricted lift function in the Maxiflow is the LIFT STOP. This CRITICAL part (lift stop) dictates whether the valve will flow its FULL CAPACITY or only FRACTIONAL CAPACITY; it can even be misadjusted to flow NO CAPACITY at all. It is vital that only qualified individuals such as GE's Green Tag Center service technicians make this critical adjustment; the consequences of a misadjustment could be catastrophic. The Maxiflow also uses a very special technique called PRESSURE ASSISTED CLOSING to achieve the tightest and most accurate blowdown (closing pressure) of any valve in the industry. These valves can consistently achieve closing pressures (blowdown) at 3% below the set pressure; significantly tighter than that required by ASME Code Section I. In addition to the traditional upper and lower blowdown adjusting rings found in many valves, the Maxiflow utilizes a third ring called an OVERLAP COLLAR. The overlap collar works in conjunction with other parts (floating washers and top plate assembly) to control how system pressure (when valve is open and flowing) can be used to assist the valve in reseating. The proper position of this overlap collar is critical to valve performance; too high and the reseating feature is NEGATED, too low and the valve will CHATTER. Inexperienced valve technicians may believe that "the shorter the blowdown the better" and will intentionally misadjust the valve to achieve a much too short blowdown which can result in chatter and reduced capacity. GE thoroughly trains and certifies Green Tag Center service technicians on the proper methods/settings to use when adjusting the Maxiflow overlap collar to ensure proper valve performance. It is a highly engineered device that requires extreme care during the repair and adjustment of its critical components. It is very easy to make incorrect adjustments that, at best, hinder its performance and, at worst, can cause it to not perform at all. Consider utilizing only GE factory trained and certified GTC technicians to perform this work, because after all, how SAFE is SAFE?

The Hottest Questions About Valves
Do you want to know about valves? Here are some frequently asked questions.1. What do you recomend for a 3/4 sprinkler valve?Yuo can get what ever type of valves you want pipe size does not change between valve brands2. How long can you race with a stock crankshaft? And how do you know when its time to be replaced?If you guys would be so kind as to give us a few details, you would get, at worse an educated guess as an answer. I am not just picking on you, but about 50% of the questions on this site are impossible to give a reasonable answer, due to lack of details. Give: Year, Make, model. Type racing, or other use. Modifications If performance related, weight, and experience level of rider. For any question, give all the info you have on the situation.You can not give to much, but one thing left out can make it impossible to even get close. I have told several folks that Answers can be the best comic strip you can read. Lets make it into a real, useable, helpful site. I, and I know several others take great pride in helping folks, and do not like the unanserable questions. I have spent over 50 years of my life building racing, and repairing motorcycles. I am no wizard, or super man, but do know quite a bit about these things, most learned the hard way, from experience. It pleases me to be able to assist someone with less experience, and to teach then some of what I know. I think many of the folks who answer feel the same way. So, help us to help you, and we all learn. Tomcotexas. Not knowing how long you run in a race, and how many a season, I will make a SWAG, in hours of running. An engine like this, I would recommend a crank replacement for each 50 hours of running. A crank failure is likely to take the cylinder, and maybe crankcase out with it, maybe even the head. The price of a crank is small, compared to the cases and cylinder. If it is at max revs for most of the time, this may be a bit high hours, if at max less than 25%, then likely safe for 75,maybe 100 hours. Hate to have to say it this way, often in racing, you do not know the limits till you blow a couple up. Keep notes of each race, you will be surprised how valuable they will be. An example - in the good old days of drag racing, a really good running Triumph 650 got rings about each month, valves, mains, and inserts - at least twice a season, Went too Sportster Strokers, Lap rods, fit new rod rollers, new mains, usually pistons and rings before start of season. Also valves if over a .400 lift cam was used. Mid season, new rings, lap valves, check anything. Big bore Kawasaki Z1 or KZ engines - build it and run it. Rings and check valves before leaving for Bonneville. Time wise, average maintenance on Triumph - 8 hrs/meet. Sportster - 2 hrs/meet. Kawasaki - 15 minutes meet. Note, this is engine/drive numbers, rear chains, tires, sprockets, etc vary. Used a lot more tires on the Kaws. Aah- the good old days. Tomcotexas.3. What are some common application for ball valves?Honestly, this is a bit of a strange question as ball valves can quite literally be used in thousands of applications in both industrial and commercial applications. We have clients that use them for simple water processing in water filtration systems, to more complex processing such as liquid nitrogen processing where temperatures drop to -320 degrees fahrenheit. They are even used in systems that move really nasty stuff like hydrochloric acid. Again, a little odd question. What are you looking to process? Maybe I can help:-)4. Why is my lawn mower giving off smoke and cutting off?First make sure that the machine has gas water free.If the gas is OK, that mower years are gone...! The piston rings or valves are shot. You have two choices: 1) Take it to the money hungry lawn equipment mechanic or, 2) Buy a new one. Good luck. ..!.
