hi, i am new to the forum.i just bought a chopper with a cb750 engine 78 model,it also hs a cycle x 4 into 2 carb and intake set-up.and it has a250 rear tire as well with a jack shaft final drive set-up. so heres my issue the best i can describe it.  when you take off or ride the bike as you throttle into it,it begins to hop excessively,unless you arehard in the throttle and it stops only for a second  and starts right back .it also sounds odd like a drag bike on the starting line hitting its rev limiter.the bike idles awesome and revs just fine in neutral with no abnormalities. losing my religion trying to figure this out dont know where to go next.. it has new chains  and sprockets, as i thought it was in the drivetrain.also can anyone tellme if you can use to different case halfs for the 5motor. please help
