Q:Someone help, I have Valve problems!?
It is not the type of valve that is your problem unless you are making a very small one to shoot frozen blueberries it is the small size of the 1/4 valve and its piping. Various Spud Gun plans show 3/4-1 1/2 piping with ball valves as well as with RainBird Solenoid (quick-opening globe ?) valves. These typically have 1 1/2 -2 barrels.
Q:inner tube valve (Specialized) too large for the hole in rim (Bontrager)?
Your rim is drilled for Presta valves, and the inner tubes you are trying to use have Schrader valves. Either buy the correct inner tube or drill the hole larger to accommodate the larger valve
Q:valve oil mass order?
Refills? okorder.com they are horrible!
Q:Digital EGR Valve - Firebird question?
Take the EGR valve off and see if it is internally caked with carbon. Also look at the ports it lines up to on the plenum and see if they are also clogged with carbon. If they are, remove the air intake tube from the throttle body and open the throttle plate. See if the intake plenum is also clogged with carbon. If so, and I think it is, you will need to get yourself a cumbustion chamber cleaning. Those 90s GM cars were bad for this. This will make it idle rough, and also lack as much power as it should have.
Q:what exactly causes a valve to stretch?
It is probably a combination of the above answers, plus heat. I would think heat is the primary cause of the stretch. As you know metal expands, when it gets hot. It will also shrink when cooled. There is probably a point where they will only shrink back to a certain spot and still remain in the stretched position.
Q:Trumpet valves sticking help?
Check that you are not putting sideways pressure on your valves when you press them downwards. Even on a good horn this sideways pressure can cause friction between the piston and the valve casing. Avoid this by arching your fingers a little, depressing with your finger's tips, and avoid the pinkie finger ring entirely. Tying your pinkie up in that only restricts your 3rd. finger's freedom of straight downward movement. Over- lubricating the valves can be as bad as too little oil. Do the whole warm bath treatment that you would normally do to clean it, add 3 drops to each valve, work horn for a few minutes, wipe valves with very old (washed heaps of times) t-shirt: then finally 2 drops again. If this doesn't work, get a trumpet specialist teacher to take it home for this treatment.(You might not be bathing it right). Failing that, check my web site's repair section. Good Luck!
Q:2006 kx250f valves? please help!?
keep looking, they never need just valves, if it needs valves, the top end also needs to be rebuilt. when your already going to be in the motor that far, it would suck to get it back together and then the piston goes or something else that was getting abused when the valves were going. if you can`t do the work yourself it will be expensive, even if you can do the work you need to factor in parts, machine shop,and specialty tools. you could set up your cr125 for way less money, and make it work for you, i`ve seen little kids and girls at the races riding 125`s and they can`t touch the ground without blocks. and you`ll love that 2-stroke when it comes time to rebuild it, you could put all the best parts in it and do it yourself for under $300, compared to sometimes over $1500 for 4-stroke, take it from me i`ve done it, i`ve raced 4-strokes since 2001. if your not racing, stay on those 2-strokes for as long as you can, they will make you a better rider anyway, and keep riding, you`ll get used to it :-)
Q:What would happen if the EGR solenoid valve isn't connected properly?
try changing the egr vac solenoid, and the O2 sensor. dad has a 1992, and i replaced the egr valve, the solenoid, all the vac lines, and the O2 sensor to get rid of a missfire, and help mpg. we dont do smog tests here, so it wasnt for a smog reason went from 12mpg to 15 mpg. your supposed to connect the egr to the normally closed port on the solenoid. should be the top port. there is supposed to be a bit of foam glued to the VENT port. check your check engine light codes, you can do it in 5 minutes by jumpering terminals A and B. read more about it online. code 32 is the EGR code, its the most common code on these old trucks
