Got it to start, but now cant seem to get it to stay running. Cyl 2 and 3 seem to barely get warm where 1 and 4 get really hot. There is a clear imbalance in the exhaust pulse also. When I finally got it to stay running long enough to heat up, I also noticed there was near zero throttle response, and that when hot there was smoke coming from the engine. I am utterly stumped. I have already ordered new seals, O-rings, and jets for the carbs. I got a new set of spark plugs, The guy had some old school autolites in it that are to cold a plug for the bike so I got the correct NGK CR8E's.
Any and all ideas and input would be most greatly appreciated....
Thank you in advance for any and all help and input!
