Hello, I'm new here and new to motorcycling. Recently came into possession of an 85' 750 maxim-x (canada) figured it would be a fun project to learn on. I'm an electrical technician on a wind farm, so while I'm not completely clueless, carberated engines are not my forté. I managed to get the bike running, after doing some minor things. The bike starts easy and idles fine. If I leave the choke engaged it will eventually ramp up to a high idle of around 4k rpm, as I understand that is normal. While in the high idle, the bike sounds great, and runs smooth. However if I remove the choke, and try to apply any throttle the bike sounds terrible, almost like its misfiring, and will sometimes even stall out at 2kish. How can it run smooth at 4k with choke but sounds like it wants to die with a little throttle? One of the needle jets clogged?
