I Am in the process of restoring my bike it is the unrestricted type 10W not the 12A. It has a Micron Exhaust system and K & N type air filter fitted. Does anyone know what Jets I should fit on the carb So that I dont burn holes int the piston and over heat her as with the standard jets it is runnin too lean?

if you have a k and n filter you might need a spacer tube that goes on the back of the carb, a ram air filter might be better,

to find out what size main jet you need you have to do a plug chop to see the colour of the burn,

what size main jet are you running
