The first longer ride displayed some clutch slippage. I did not replace the clutch when doing the rebuild, for reasons that must have made sense at the time.
Fortunately, I had a complete clutch pack new in the package, and it is quite easy to put the new ones in.
So now the clutch works great and I got a very early oil change- never a bad idea to do initially (I think). There is just two screens for oil filter and a pretty large capacity (2 quarts) for an engine this small.
It is so much fun to ride now that it shifts right.
