Engine backfires when shutting down

4 posts in this topic

I have noticed at times that my bike will make a kinda backfire at times when i shut her down, not loud, just like a PUFF noise. is this a jetting issue? am I too rich and gas is burning in my exhaust after i shut down.

Don't worry about it. Not all fuel is burnt at idle, and carb doesn't work properly either.

This is why when tuning carby, you have to turn the idle up.

No i removed the smog stuff, it seems better once she is fully warmed up, like you said some gas not burning good at idle, I did idle her up a bit, and all is good now.
