After fitting the 4deg advancer to mine the other week and not initially being impressed; 'I stand corrected'...
I did the London to Brighton on Sunday, which was the only decent run I've done since fitting the advancer.
Not only is it smoother, responsive and just as pokey, I've managed to get 215miles out of the tank with 4ltrs to spare!
Usually it's around 180miles per tank +/-
For my bike in particular, and I've had her now for almost 10yrs now!, it's been having some issues this last 12 months; starting, running, missing, cutting out etc... I've addressed everything electrical and fuel related including removing the alarm; the alarm being the main culprit!
The 4 deg advancer has been the icing on the cake which has finally reinstated full confidance of my old girl...
I wish I knew to do this years ago...
