Shifting from 1st to 2nd and from 2nd to 3rd, my Liner backfires if I let up on the throttle between shifts. If I keep the revs up a little while shifting, I can avoid it. To my experience, backfiring is indicative of an overly rich mixture, but the bike has a Roadhouse slip on installed, which I would think would lean out the a/f mixture, if anything. Popping could be the result of a lean mixture, but this is definitely backfiring.
I read somewhere that the efi on these engines is in a closed loop, except for idle or lower revs, where it goes into an open loop. Would this possibly be the cause of the backfiring, and if so, what can I do to correct it? Would going back to the stock exhaust help this situation?
