Backfire after tors

[atomsplitter]

If you're going to do a dealer install they have the program to reset your ECM so it has proper timimg and fuel curves for the change. If you're using a Tuneboy, you can fiddle the numbers until the exhaust runs like a 1942 diesel tractor going uphill pulling a big load. It won't pop anyway.

Backfire comes from a too lean mix, increasing the fuel ratios at part throttle will add more gas and reduce the potential backfires and limit fuel economy. How to do that with a program is where you need to get more info than I can provide, I don't like fiddling fuel ratios on anything past 1972 technology (just read my Confessions of a Motorcycle Nut, Entering the Jet Age). (I have a Tuneboy I use sparingly, still swimming in the shallow end of the cybernetic gene pool).

Have the dealer download the tune..... you'll be fine

Dealer tune won't completely remove the popping on decel...gotta' do some fiddling with the tune to remove it completely.

kinda don't mind it, every motorcyle I ever owned did it so I think it's normal. You got loud pipes you're going to get some popping on decel 8)

I think the cat is in the pipes, change the pipes and the cat is gone. I have heard something like that from someone who has done it. I could be wrong

You should be able to get rid of the LEAN backfire with proper tuning with a TuneBoy. My Harley never had the backfire, if you can find a good tuner he should be able to tune it out.

Red Rocket is correct. The cats are in the muffler housings. Any set of aftermarket pipes for the R3T eliminates the cats.
