G5 has 'lecy start CJ is kick only, apart from that mostly same.
BEFORE you lay out on an exhaust remove the top cover and check operation of cam chain tensioner and state of camchain plus cam bearings all it will cost is time + gasket goo. Clean out centrifugal oil filter on end of crank. At one time you could get pattern silencers to fit original front pipes. Mostly same as CB360 (more common in US) and i think Dave Silver has many parts.
650 plug give me a call sometime and i will talk you through it as best i can.
Any other help ask and i will try
Regards Bryan
