Anyone have a link to a step by step how to adjust crf100 valves?

There's one by BBR on Youtube fof the crf50 that makes it simple but my kid's 100 is starting to make a little valve noise. They're totaly different.

Pull the ignition and valve cover.
Line up lower timing mark on flywheel "T"(=top dead center) with the small arrow marked inside the engine cases at 12:00.

Upper camshaft Timing chain gear mark "0" 12:00 as well, with the 2 timing chain gear bolts level(horizontal)

The Camshaft lobes must be pointing down, Both valves will be closed.

Check clearance intake and exhaust .05mm or .002 in ajs the valve rockers set screws and lock nuts.

Good idea to ajs the timing chain first, its spring loaded.

Hope this helps. Good luck:thumbsup:
