hi can a ignition switch and or wiring harness from a550 f2/f3 be used with a 500 k1 engine had weak spark now none.
The bike f3 550 usa had k1 500 engine fitted , I have installed a wiring harness that came with bike 550 ignition barrel
I do have a 550 engine on bench but the 500 engine is good low miles 9,000 quandry
