Q: I have my head off now I need to change my valves how do I do it?: It can be different from car to car, look up tutorial's on google and youtube for your specific car

Q: i need to know the setting of the valve and a little advice on the up and down of the valves: As Bob said, you had probably best bite the financial bullet and get someone experienced to do it. With the bucket over shim designs, the shim you need to change is underneath the bucket, the device that rides against the camshaft. To change the shims, you have to remove the camshafts and when you replace them, you must get them timed exactly right or else you can have pistons hitting valves..not good at all. They put the shim under the bucket to keep the cam from spitting the shims out through the valve cover at high rpms. The older 2 valve 900-1000-1100-1300 Kaws have shim over bucket and can be changed with a special $20 tool, a little screwdriver and small magnet . However, you might consider getting a shop manual and checking the valve clearance yourself. If all are within specs, then there is no need to take it to a shop. My old KZ1000 went something like 110,000 miles and only need two shims changed in all that time, so your bike could very well be ok.

Q: okay, so i have a 2003 cr125 that i wanted to trade for a 4 stroke bike, and i found someone with a 2006 kx250f that wants to trade. He said all the bike needs to be running are 4 valves. The bike is in very good condition from the pictures i saw. How much are the 4 valves going to cost if i bring it to a mechanic shop? is the trade worth it? or should i just keep looking? thanks!p.s.- my cr is in absolute mint condition, and i never even rode it because it is just to much bike for me and i am not use to 2 strokes: Kx250f Valves

Q: i just bought a junky trumpet, didnt come with a mouthpiece... how can i tell that the valves work? They press in and dont stick, but im not sure about their functioning.

In college, I switched to and nonetheless at present play a Monette B2, that's analogous length to a a million a million/4C, and characteristic an excellent sound, and might play a intense G (4 ledger lines above the staff) and up on it. i exploit it for any group I play in, marching, stay overall performance, musical theatre, etc... ultimately it boils all the way down to private preferrence. %. the mouthpiece that feels the terrific to you and nonetheless can provide a good sound. you do not pick it so great and deep that your variety and sound go through, and you do not pick is purely too small and shallow which you get too outstanding and tinny of a sound. wish this facilitates.

Q: where is the heater control valve on a 1996 volkswagen passat: i'm no Ford fan, yet a Mondeo resources of a similar fee might want to be my determination. Neither Passat or A4 are fairly good, and service prices for VAG diesels are astronomical. once you're insistent on an A4 or a Passat, ?a million,00 is going to get you a finished smash till you're prepared to spend a lot of time being dissatisfied by utilising the final public of autos on the marketplace.

Q: How do you know if you need a new EGR valve or if you just need to clean it?: You obviously had a parts store diagnosis so maybe you should ask the person that put the idea in your head that the EGR was a problem for the answer.
