Gen5 gear position sensor is different and shift drum connection to sensor is different. Not done it myself, but heard of prject where gen5 engine went into gen4 bike and he used gen4 gearbox only to match gp sensor with gen4 electronics. Does gen5 drum works in gen4 gearbox needs confirmation?
Gen4 race: high spec.
Suzuki GSX1300R Hayabusa 2013: stock.
Kawasaki KX450F 2016: love it.
