09 250R bench valve adjustment

Recommended Posts

What is the proper procedure for adjusting valves with the head off the engine?

I would install the cam in it's TDC orientation (lobes not exerting pressure on the buckets or rocker arm),

torque the camshaft holders to spec (usually 12 lbs/ft. but confirm with your service manual) and set the clearances.

 

Once the engine is fully re-assembled, rotated by hand a few times to confirm there is no binding,

with the cam chain now under tension recheck everything again.

You might find the left side intake valve clearance to become a bit tighter, re-adjust if required.

Thank you!! I'll do just that and make sure I do the re-check.

Push down on the cam gear when measuring clearances
