plug the pair hose if you dont like it. it will do that on every hard downshift.

Just a bit of extra fuel burnin' off, air, electric, & quik shifters will also add to the show when the brief kill times pull in fuel and relite
BTW, just seen your post count- WELCOME to the Org!! Be sure to post up some pics of your Busa, we love pics

get it mapped, contrary to popular belief you are either very rich or lean. A rich condition will let fuel puddle in the intake until you crack it open like that and it will ignite all of it. However, lean will cause popping and sometimes the fire from the exhaust. I would get a map in there quick if I were you.

ok thank you when i bought the bike they had a power commander under the seat but not pluged in because the plugs didnt match the bike does that mean the power commander dont fit that bike or is there adapter they make thats probably a dumb question but im new to this ha thanks again for your help

ok the model number is 304-410ex ,it backfires when i revv it up can u tell me what this useless dynojet fits and wheres the best place to get a sprocket cover thanks

I don't know what it fits, just that it don't fit yours....
Call DynoJet tomorrow and ask. 800-992-4993
If it doesn't backfire under a load (when accelerating) I wouldn't worry about it. Lots of bikes spit and sputter when you rev them.
Sprocket cover supports are available lots of places, I would start by contacting one of our board sponsors (Cloud 9 Performance would be my first choice) and seeing what they have to offer.

Think TPS over fuel feeding. You rev the engine up, the TPS says more fuel, you go back in gear, the over rich rev read is now sucked into the exhaust. You go back in gear releasing the clutch and start to feed throttle again. That sets off the flow again. WOT lay waste in the muffler is re-fired with a push out the back. Back-pressure is fresh air to help flame that out the pipe, which I think is about 9" deep from the tip of the exhaust back up inside is that re-ignition and/or pop she poops a little flame is the after-noise like thunder and lightening?
Light wave is faster than sound wave travel.
I have an un-chromed custom made pipe(s) with burn marks around the outside of the pipe that match the other cylinder's exhaust [straight] pipe. That is where I see a heat ring 'exchange' about 9" up the pipe. So, it is an unscientific guess. There is no spark in the pipe anywhere, so that flame has to be lit [fireball] or it is on a pre-lit heat molten liquid range [no oxygen in the exhaust] that moves down the pipe and somehow ignites in flames out the tailpipe once it meets some oxygen again to show flames.
There has to be a way the ball of fire moves in steps. I may be mis-stepping, but some of that popping has to speak the science somehow in the physical world.
