I have a issue, when my bike is cold I know the oil is thick and the engine is running quiet. When the oil heats up it gets thinner and the engine valves start tapping.

I know it not in need of a valve adjustment because I just did it.

I ran 10w-40 in mine and it was ok.

is 10w-40 thicker than 10w-50, I know I would need an heavier oil.

10w-40 is thinner try 20w-50 or straight 50 weight

I always ran 20W-50 in my '89 ZX750 and it never had any problems.
