So for shit and giggles I wanted to see how loud my muffler really was . At low RPM's ( I do a lot of town riding ) it sounds beast . So after I let my bike warm up I reved it up almost to tack it out maybe about a thousand less from tacking and notice my muffler spit flame ! I was excited but then thought mybe its doing it becoouse combustion if off ? Idk u guys tell me . Bought the bike this way. 160 across w/ D&D slip on

Is the air /fuel mix right ? What can cause this ? Does this have to do with the muffler its self ?

lots of unburnt fuel in the exhaust will do it. Happened while working on a friends bike. Looked really cool in the dark.

So should I check my float hight ? Smaller jets ? Pilots ? What about spark plugs ? ... Or should I just leave it as is ?

a rich condition will cause that. but the fact that you reved it close to red line, with no load on the motor could be the culprit. My dirt bike would shoot flames while I was reving it waiting for the gates to drop. The carb was tuned and I was running pump gas.

The Jetting of the bike should be set up so that, when at speed the ram air is functioning, so more air means more fuel needed...

when you are at a stand still you are still dumping the same fuel in but not burning it because there is not enough air, so you have a rich condition...


if you are saying that you are running 160 mains across that could be part of the problem, the outside cylinders are running too rich...


best to pull the plugs and read them...
