SOURCE: cam/valve clearances
my mate says that if the gaps are bigger then its ok and that it's when they are smaller that u need to do something about them is this true? bit of xtra info: the manual says inlet 0.15mm and exhaust 0.25mm clearance. my bike measures inlet 0.20mm and exhaust 0.30mm i'm just a bit concerned 'cos if the worst happens i wo'nt be able to afford a top end rebuild.You should try and keep the clearance to 0.15 in and 0.25 ex. With the de-comp it is cridical to have the exhaust clearance correct. On the early 400/450 they had some cam problems so check the shim buckets and cams are not worn.,

I doubt that any gears are stripped. Believe me you would have known it when it happened at 40mph which is where you would have to be in 5th gear. This is a bent shift fork. The actual gear is fine. The slider gear is not moving far enough to engage with 5th gear. The YZ does tend to have this problem in 5th and 1st. "Dirt rider Magazine " did a story on it. Best to let the shop do the repair as the entire motor gets torn down into about 100 parts.
Please rate this solution. Thanks!

SOURCE: timing chain 110 hymoto pit bike
Put the piston at TDC (Top Dead Center) by lining up the timing marks on the flywheel and stator. Put the cylinder head back together with the cam installed so the high points of the cam lobes are pointing kind of downward. Pull the cam chain taught on the front side of the engine. Put the chain on the cam gear such that, when bolted to the cam, the index mark or marks are in the proper position.
The proper position depends on what markings are on the cam. Some bikes have a single mark; an arrow, a straight line or an "O". The mark should line up with the center-line of the crankshaft. If the cam has two marks opposite each other, the lines should be parallel with the gasket surface. You will need to rotate the unbolted cam left or right just a bit in order to match up the bolt holes to the gear holes.
Can I get a “very helpful” rating on this answer?
