jetting could be out a bit. do you have the spark arrestor still in?

 

no my spark arrestor is gone

 

your lucky, i wish i had fire coming out of my muffler, that would look so sweet (is that why they force you to have spark arrestors to prevent forest fires?)

 

also could be a sign opf running on the lean side.

 

I am gonna put this on the MV. Uh,......you know, to start the campfire

NIIIIICE!!!![img]i/expressions/face-icon-small-cool.gif[/img]

 

arent they just like adding a spark plug to the exhaust to ignite the fumes. see it on a hot rod once. nice flame show. you get caught riding w/out a spark arrester up here and its a heavy fine i do beleave.

 

a sign of being on the LEAN SIDE???? how could there be a flame coming out of the muffler if it was running lean, whihc means that there's no fuel left when there is still some air left. I think you meant rich, then there would be too much fuel that is left unburnt so it comes out the exhaust pipe. I held my hand just in front the the endcap on my dad's eiger when it was warming up with choke on, and after 5-10seconds, my hand was BLACK
