backfiring?

My SH backfires sometimes when stopped or slight revs, but never under load. Is this normal?? It is all factory.

Re: backfiring?

Well, let's clarify something first. Does it backfire through the airbox or afterfire (also called backfiring by many) through the mufflers?

If it only happens once in a while, well...... welcome to the "character" of the superhawk. I hate to say it's normal but it's a common thing. I tend to think of it as a hiccup.

Re: backfiring?

as far as the hiccup goes, i tend to look funny trying to "burb my hawk by gently patting its gas tank!

I don't think that vent rerouting fix makes any sense.

NOrrTH is an unknown quantity at this point
Re: backfiring?

My bike stopped burping, grunting and farting the instant i removed the PAIR system. Best money I never spent.

And I agree about Greg being a VTR god although we seem to have a few members here that could be at least cannonized.

go there, read about the pilot circuit.. then youll get it. your bike is surely running lean. beef up pilot jet for major adjustment IF and only IF you adjust the fuel/mix screws les than a 1/2 from factory setting and you dont have a constant cruise speed without fluctuating throttle position to keep that low ide, 1/4 throttle speed.
