thanks been looking at that
can you do anything on the gearing on the j50
also is the j125 and j50 the same engine with different top ends so he could just fit a j125 top end

There's sprockets available for the kit but although the 50 and 125 are both 3 speed I'm not sure if the top ends are interchangeable, the crank would need changing at a guess. Try the Luna forum as someone's bound to have done one. Or consider a new motor. http://www.scooterrestorations.com/lamb ... -assembly/
