General Discussion / Synthetic oil and our KO clutch???
« on: January 14, 2011, 03:54:54 am »
Greetings! When synthetic oil became available in the early 70s,I tried it in my sandcast crankcase and it fried my clutch.I was told then that it wasnt compatible with our wet sump clutches.Has anything changed or do I just stick to my more slippery than snot Valvoline racing 20/50...thanx, _Tim
