Clean the carb. The inlet needle is gummed up. Also look at the carb boot. They can crack and let extra air thru. It causes lean air fuel mixture. The blast's lend them selves to a lot of customizing. Don't let other's dog you on owning a blast there great bikes. I own one along with a s2t, s1, xb9s, and a xb12scg.
