Note on the valve service for the Yamaha CP2 engine: The CP2 motor has twin overhead camshafts and a timing chain. Checking the valve clearances is a little tricky due to clearance, but adjusting them is trickier as you have to remove the camshafts, secure the timing chain, remove and replace the buckets (possibly replacing shims), then re-install the cam shafts and the timing chain with the correct timing.
