So when you're on the gas, it's backfiring? If that's the case, i'd check the timing.

It shouldn't backfire while accelerating. If it backfires between shifts, that's common.

You should change it ASAP.

That's fairly normal. Caused by unburnt fuel and backpressure in the exhaust system. Not much you can do about it.
