ok i know this might sound wierd but i want my bike to back fire flames. it back fires alot now but i want it to spit flames aswell. any suggestions?

well, i could probably help you to stop the backfiring...

but more flames?

i think they just run there bikes rich.

is your exhaust rotten and in holes?.. backfiring can be a symptom of this

afterburner is what you need ,

or make your own out of a spark plug.

Over fuel it. up rate the jets etc then you should get flames. My mates Buell shoots flames a lot on the back fire but it is making 185bhp at the crank! lol
