My Valve Clearances

6 posts in this topic

I'm doing a top end in my 06 yz450f 67hrs and my valve clearance is INT .15 .15 .13 Ex .20 .20 should I leave them since there still in spec or get them closer to the middle of spec?

Don't bother them. They're all in spec.

The whole range of .10-.15mm or .20-.25mm is only a .002" spread from tight to loose. Why sweat over .001" if it's already where it belongs?

Right On, I'll just leave them alone then, Just figure while I have the head off for the piston and rings.

Thanks Guys
