Flame means it's running too rich. It is in spent fuel igniting in the exhaust. It may look cool but it means its not running right.

this is tight, the exhaust is not big or to small, perfect, nice sound the way a sport bike should sound with the added falme to it, nice perfect.

nice sound

whats up with the backfiring?

[tfcalhoun]

@BrutalDavis

Typically it is just excess fuel, in this case it is probably the air injection that stock bikes use for emissions (like a smog pump) which basically mimics an exhaust leak so it is pumping fresh air into the exhaust which raises the temperature of the exhaust to burn off excess emissions. On race bikes excess fuel is often used to either improve acceleration out of turns or to sometimes soften throttle response and that is why you sometimes see flames from race prepped bikes.

@tfcalhoun well yea but in this case it does nothing but burn the valves am i right? you arent supposed to have backfiring on a stock engine like this it means that you are running to rich if i am not mistaken and it needs to be tuned.

[tfcalhoun]

Yes this is a stock motor
