But when downshifting from 5th to 4th, 4th to 3rd, and sometimes 3rd to 2nd I have more frequently been having one loud backfire.

Here's something I'm just throwing out there for you to check, take a tissue or something really light and soft and hold it around your header pipe where it connects to the engine and see if you have any air leaks in your gasket seal... I've been told that it could cause backfiring and that's easy enough to check... I in no way, shape, or form know from experience, nor am I a mechanic.

I cut the throttle at an underpass and it fired off POW, POW, POW, POW,POW,POW I just cracked up...

I went out there with a candle the other day and it blew it right out. My header bolts were a bit loose. I tightened em down. Backfiring didn't get any better. I bought a new gasket though. Was waiting to put that on when I replace my stock muffler with a Dyna I have sitting around.

In my newbie opinion, the Dyna muffler is just a cheap replacement for the stock muffler, but some people love them and get them sounding really good... go ahead and hold that candle up to the header gasket seal again to check for a leak, go all the way around the circle, then check every other connection on the muffler, and make sure your idle screw is set right... if your stock muffler is in good condition I'd just change the header pipe gasket seal, or get a Supertrapp, change the header gasket seal, and rejet... and I'm just speculating from my own Dyna experience... I don't know too much about bikes but I know I had my idle screw setting messed up once and I was backfiring so much I thought someone was gonna call the cops... Cheesy

But remember I'm new to this stuff...
