Its because your engine is now running to lean with the new exhaust. You need to re-jet to richen it back up

You are either lean on the pilot jet, or your exhaust was not installed properly/has a leak. Try richening up the pilot jet a size, if the x6 is the only mods you have, then bump up to a 42 pilot jet and try that. More than likely that is your problem, but I did have a leaky header on my HMF full and had to send it back for a new on to get the flames to go away...:rolleyes:

no i did not rejet because the guy said that the jetting should be very close from the last pipe the whitebros because that one i had on when the rebuilt my moto and he say he may need to adjust the aifluescrwew to richin and we did if i rev the quad really high and let of the gas it pops som time blue flames
You need to rejet to fix the problem I don't care what the guy told you.
