I just took a short ride (27 degrees) and noticed that under hard excelleration, the bike cuts out, pops, spits and shoots flames out of the exhaust (kinda cool). This only happens under hard exclleration. Otherwise it starts, idles and runs fine.

Any ideas? The carb is a CV with a tuning kit on a stock Evo with hand made exhaust.

you got to re-jet that carb.

I can tune a radio like a son-of-a-bitch, but maybe not a carb. Any further insight?

I dig the 4Q btw.

What do the plugs read like? Was the bike warmed up ok and have you checked for intake leaks?

It did have an intake leak that apparently was fixed. Haven't pulled the plugs. It was warmed.

Could the intake leak be the sole cause?
