Thanks alot for your help guys... I did talk to him and told him what you guys suggested. He said he was going to get a a 44 slow jet. Excuse my ignorance, but is a slow jet the same as a pilot jet. He said the bike is running 125/40 but was thinking of going 42 or 44? Could this be the fix that you are mentioning?

He said he dipped the carbs in acid and cleaned them but he doesnt think the pilot jets are clogged. The bike does crakle a bit when it decel i thought that was just cause of the 4 - 2- 1 header. It does rev up smooth though, if i could only get to idle it would be at home...

Another question... Does anyone think this could be a spark or coil issue?

Thanks for all your help. I will keep the forum posted on what happens.
