Hey i have this 125cc pit bike. I wreaked it last year some time and it has been sitting a long time. And i just replaced the swingarm so im in buisness agian. I have new gas in the tank, i took apart the carb and sprayed a lot of carb cleaner in there.

HERE IS THE PROBLEM THE BIKE ONLY RUNS WITH THE CHOKE ON. IF I GIVE IT GAS IT DIES. So i dont know what to do.
Can you guys please help.

 

Sounds like a clogged jet. Could be the main jet or the pilot. With a carb that small, it only takes a very small piece of debris to clog it up and throw everything for a loop.

 

bump>> any knew ideas i have cleaned the carb and i did have a clogged jet( i think it was the pilot jet).. the bike will at least idile now but i still cant give it any throttle it just dies as soon as i crack it. Please help.

 

Air leak between the carb and intake manifold. Or stuck float valve. Or clogged main jet. Those are my next best guesses
