Backfiring

[FriedRiceARoni]

My bike has been backfiring a lot recently. Does anyone have any suggestions as to why, and is this common? The bike runs fine otherwise. I thought it was from adding SeaFoam to the gas tank before and it was clearing out a bunch of crud from having it sitting (previous owner's doing), but that should be out of the system by now. And it doesn't do it all the time. The last time I took it out for a ride it didn't backfire at all.

Did you replace the exhaust, new filter?

Maybe its due for some slight tuning? Plug change?

my bike backfires when i cruise through the neighborhood while coming up to the stop sign.

if i take off in first gear and go around my street to the next stop sign, i'll keep it in first - as the rpms are coming down, i can hear it "boom boom.....boom"

sounds awesome lol.....

It is lean and/or you have an exhaust leak?

It's more of a shuts off/restarts... But it backfires when it happens. The bike is all factory, the plug was changed prior to us buying it, and the coil was replaced, but it was doing this before the coil went bad.

Is it possible that whatever caused the coil to go bad is causing it to quit working intermittently until it actually goes bad?

Sorry Fried,
My comment was more towards Litos.

With the new info you may have a bad plug wire/connection, a timing issue or ignition issue?
