Does it smoke loads after you've been using it for a while? What 2-stroke oil do you use? The cheap stuff tends to be smokey.

EDIT: that's if it's a 2-stroke Laughing

basically when i first got the bike which was about a month ago i went to start it a few days after and it wouldnt, the spark plug was clogged with black sut. i cleaned it and it started spot on. i fiddled with the air screw and it made it run fine. how do you set the air screw properly? anyway could the reason its smoking be from all the sutt and oil its built up in the engine and in the exhaust?

Ride it for 5 minutes and it stops smoking

It's not a problem

As far as i can remember the speedy's have a cable operated oil pump towards the rear of the engine can't remember which side, So you could check that the pump is set right and that the cable/ pump operate freely, I could be that the pump is stuck full open or that the cable isn't returning fully with the throttle closed.

Most two strokes will smoke but not realy heavily, unless someone has put oil in the fuel tank as "a bit of extra protection" or accidebtaly put some diesel in, seen that a few times with the Usualy accompanied by "It was running sweet then i filled up and it started smoking and now it won't start", I make a point of smelling the petrol tanks in not running mopeds now just in case.
