200s Clutch slips

[BigRed_Ryno]

After rebuilding te top end of my 200s, ive taken it out for a test run, only to find that anything more than half throttle, the cluch starts to slip. Now, when i had the engine in pieces the clutch plates were all fine, i was wandering if this could have been caused by using the wrong type of oil (10w 40 part synthetic motorcycle oil)
or by flushing it with diesel when i rebuilt it? any thoughts would be greatly apreciated

I have heard that synthetic oil will make the semi-automatics slip some. I would change oil and run plain old 10W40 (30)

[BigRed_Ryno]

so do you reckon just changing the oil will do or to change the clutch plates now they're contaminated with synthetic oil?

Try using some 10w30 with an API rating of SEor SF.

I'll give it a whirl
