My 200d is now back together and fired it up to do jetting. It bogs on bottom end when you hit the throttle. Tried adjusting the air screw and didn't help. would leaning my needle out help. When the motor is revved up it seems fine, but just off the low end it dogs. I thought I had a clutch problem, but thats fixed now and still seems like its slipping untill the motor revs up and its fine. If you put it in 1 or 2 gear, and hold the front break and gas it, the motor bogs and the wheels won't spin The clutches are new and are correctly adjusted so they are not the problem. PLEASE HELP ME!
