So, I have drilled out my baffels & when I let off the throttle the bike backfires all the time. I have bought the FI2000 & it is set to the stock settings of 1,2,0. I have also tried it a bunch of different ways with no luck at all. It almost makes me wonder if that part does anything. Next I started reading on here and read that if you plug the pair valves it will stop the backfiring. This did help out alot but it still has not stopped the backfiring. Anyone else out there having this problem? Or do I just need to hurry up and get the cobra slashdown exhaust on it? Any and all suggestions would be appreciated.
