How To Check Valve Clearance

by Gaz

Hi I have a TM 250f. I've replaced two valves - how do I measure the valve clearance and what position should the cam shaft lobes be when checking so as I can replace shims.

First rebuild on a four stroke. I know how they work setting up timing etc. Have had two strokes for years and know four strokes are a bit more complicated but just don't have much spanner time on them.

Cheers for any advice.

- Out of my league.. Anyone?
