alright everyone i just cant get my bike to idle right atall and when i get it to run, any time i try to give it fuel the power lags (like if you havent got the air box on correct) then i get fuel comeing out my airbox.i have clear'd all jets and put everthing back in place a few times but cant get anywere.makes me think its to do with my air/fuel mixture ,ive tryed to ajust it but the carb keeps flooding. this problem came out the blue when i was going out one day i heat the bike up in the morning and it was fine , pulled it out the van and it wouldent go can you guys help ? please
