clearances

98 YZ 400 - would like to check the valve clearances in the morning but not familiar with Yamaha 4strokes yet. Bring it around on top dead center on compression stroke? and what kind of clearances am I looking for intake and exhaust?

Thanks alot, Randall

Check at the top of the YZ forum. There is a sticky there for common threads, look in there for a weath of info. Manual info should be found here.

A better manual site is:

http://www.yamaha-motor-europe.com/community/service/manuals.jsp

The ones you get from there can be printed.

There is a valve adjust how-to in Common Threads, as coop said, and the clearance is .10-.15mm intake, .25-.30mm exhaust. Adjustment are done with shims. Camshaft torque is very important.
