my bike was all warmed up in my driveway so i was reving the engine hard a couple times like up to 10 - 14k rpm and at somepoint my mom and my brother said they saw something blueish and fire like come out of the tail pipe... i dont have anymods to make flames come out of the exaust so what the heck is going on.

 

it happens bro, unless its constantly flaming on low rpms to high then i would be concerned. ive seen it plenty when ridin hard and fast....

 

haha alright man thats good to know thanks
