Fuel Quality

[Chris Canning]

I know it's been done to death both on here and just about any other forum,but since my stepper motor went belly up and I had to fit a new one I've aquired a different bike character wise and one of the things that has changed is its liking for 98 Ron,while away last week at the 200 I noticed it was a lot more vibey when I had to settle for 95 because not all garages sell it but when I could just gave the motor that touch more go and less vibes.

The French run 10% ethanol in 95 RON but none in 98 RON so that might have a bearing.
