Question about 2003 Yamaha YZ 250
I dont know anything about 4 wheelers. can someone please tell me step by step how i set the valves on a 2001 350 yamaha warrior? your help would be greatly appreciated
It is a simple fix. you can get the specs from your local dealers parts person. and the valves are under two caps on the top of the jug. the caps have two small allen screws holding them on. just remove the caps, you will see the top of the valves, there is a small jam nut with the top of the adjuster sticking out. it has a small slot in it. loosen the jam nut, then check the clearance with feeler gauge. turn the center of the adjuster with the slot in it with a small flat screw driver to adjust the clearance. then tighten the jam nut. if you have any experience working on engines this will be a simple thing for you to do.

HELLO; Im a partime quad mechanic, so here goes. The easy way is to remove the front fender and fuel tank, now there are two plastic plugs on the left side of the motor down by the shift lever one is larger than the other, remove both then there is a large round cover on the left side of the head, with two allen bolts, remove that.NOW.... the fun begins,witha socket on the nut down on the crank turn the engine over clockwise you will see a T come up aline it with the pointer on the case, now look up and see if the pointer is alined with the cam on the head it has a pointer up there as well,when you get these alined then you can use a feeler gauage to set the valves,I forgot, remove the two covers both front and back on both ends of the head and you will see the valves then proceed. If you have trouble you can get a manual on a disk for about $6.00 on line or hard copy. GOOOD LUCK.......GREASY

On each cam make sure the cam lobes are pointing up,, do one at a time. get the shim specs from the dealer and using feeler gauges check them.. lets say its .008 to .011 thousands clearance put it at like .009
