Sounds like a carby issue ..is it like idling bad after it comes off the choke??

if your bot familiar with that particular carby I recon you may have missed something...very small ports in a 15 carby. Also are the tappets adjusted.. takes care of another issue :)

OK, lets start with the very simple things, which is ALWAYS the best place to start, have you at least had the plugs out and had a look to see if they are Both the same?? (I guess it is a twin cylinder) if one is odd, then you may have a dud/wet/breaking down coil, at the very least, plugs are cheap, so replace them anyway! after that, get back to us and we can proceed further.
