Well fellas here the story a while back my old lady bought me an 01 blaster for my birthday it needed a new pistion because i am certain the previous owner ran it with straight gas for weeks, but anywho the bike had an FMF Fatty system, boysen reeds, no lid and a K&N, it was bored .60 over. so i had it bored up got a new pistion in and before too long it was running but here is my problem it runs great when i start it then it chokes out after a few seconds i know the exhaust doesnt seat well at the motor could this be causeing it or should i look into the carb. Oh and I sold my old blaster the one in the avatar pic ill post new pics soon
