So as i fix one thing another turn up to keep me interested :-)
A couple of days ago GRiSO has started to buzz, and today I have just done 300 miles and it buzzes, quite loudly (with ear plugs in) from just over 3000 revs to about 3600 revs. It is worse in fifth and six gears, but will happen in all gears. If you pull he clutch in it stops so the buzz comes from the vibration of the motor. Stationary there is none!
I guess something has worked loose and I will go around it in the next week, (day off tomorrow but at a track day, not on the GRiSO).
Anyone got an idea of where on the bike i should look. I have been holding on to things as i have ridden and nothing is loose, took the wings off and there is nothing loose under there either!
All help gratefully accepted
