exhaust popping and fire!

I recently baught a '01 yz426f as my first four stroke bike. and when decelerating from a high rev, it will pop and a flame will shoot out of the silencer for a split second. Am i jetted slightly rich or lean? id apreciate it if someone would help me out.

lean vanilla! lean!

or bike just cold. where at in MI are ya?

sterling heights, about 30 minutes northwest of detroit. and i thought the bike was fairly warm when the problem occured. just thought maybe it was jetting. I feel stupid asking a question like this because im fairly mechanical. Im a technitian at North America's largest outdoor power equipment dealer, and only 17 years old, so its unlike me to ask a question like this. I just wanted to do everything right with my new bike!

I AM HAVING THE SAME PROBLEM CURRENTLY WITH MY 01' AND TRYING TO FIGURE OUT WHAT TO DO WITH IT. MY MECHANIC AND ME ARE GOING TO WORK ON IT TONIGHT AT MY TRACK! I WILL POST AND LET YOU KNOW WHAT I FIND OUT! FRANK SORRY ABOUT THE CAPS! IT IS VERY EARLY! FRANK :)

Does it run well except on decel? The only time I see/hear flames in the silencer is when there is an ignition problem. Check the plug first.

Good luck,

mwc

FIRE HGUGHHTHGHH FIRE FIRE

5 points to the guy that figures out where that came from.

I was thinking about it today, why do we thumper guys get all worked up about popping on decel, when every single GTU car blows 3 foot of full blown flame out the pipe on decel?

Hell whats more intimidating for a two stroke guy to see? The guy that goes blowing past on a thumper, the giant flames come belching out when he forced to reel in the beast for the corner? Or some quiet smooth XLish putt putt that cruises past with a wisper? :)
