Back fire problems

[spanishrider]

Hey I have a busa with a custom pipe and normally when I'm on second gear and let the trouthe go the flame that come out from the pipe is like 12" long I feel the bike with power but how I can tell If is a back fire problem or is the custom pipe normal setting if someone can help me with this I will apreciate it

I really like the fact of the fire come out normally is so big that anyone can see form have mile far away and make others stay far away from is really cool !!! I just want to make sure is normal and not a back fire problem!!!!

Pair mod or do the marble mod.

Did it do that with the old system? That sounds like some out of sync TB's.

You definitely need to do at least the marble mod. You run the risk of burning valves, not to mention the extra heat in the exhaust. But I do agree, the flames look cool.
