i know there is something wrong with that and like zavodi123 said the timings out so the valves are not shuting off at the correct time. but i was just saying how i can make my one backfire. its well funny u can scare the shit out of people hahaha

No, something is not okay on that bike! Might be too much space for the ventiles..

what u wanna try if u got 1 of these mean machines haha is ride in a gear at high rpm then turn your ignition off, prime the engine with the throttle and turn the ignition back on. it should give out a loud bang as all the un burnt fuel which u pumped into the bore when the ignition was turned off, will igntite when u turn the ignition back on causing a bang or BACKFIRE!

Or the ventiles are not fully clothing.

I only got one big flame (and a really loud "BOOM") after turning off the engine.. zavodi123 is right. Your ignition is off..

Your timing's off.
