Hi, that's very helpful, I have just done a service so maybe I slightly over filled, it's hard to get right on this engine as no sight window and two sumps so you have to part fill start bike then turn off and put some more oil in, and when checking oil the manual says to start rev five times turn off then check oil level, a bit hit and miss idea I think. Mileage is 8300 so hopefully no engine wear problems yet surely, thanks for help.
