Misfire

[motomartin11]

Update: mate has sent me a vid of the plug firing on tickover but then not firing when the engine is revved up?
Looks as though I'm going to need a set of new after market pick up colis from Electrex.
Also the rotor is loose on the crank damaging the end of the crank.
My mate found that the crank nut was loose.
He reckons he can effect a repair of this however.
Carbs are cleaned up and re-assembled.

Hopefully caught in time? Because, certainly on 916 model bikes (same basic crankcase/shaft design) there have been a few instances of the nut loosening and the resultant vibration destroying main bearings, cranks and even crankcases...
