Popping on decel

[CB4ME_imp]

Here's a short clip of my CB1100 taken to capture exhaust sound. Bike was not fully warmed up.

I've lived with popping between upshifts but have never seen it from this perspective.

If/when I have Don do an ECU reflash, this will be one issue I'd like him to address.

Did you do the pair valve plug/mod? That took away all the decel popping on mine.....
I will say, when I gave it to Don, I removed the pair valve plug/mod, he did his ECU work, said it was OK to block the pair valve again, but I never did and it sounds OK, pops/gurgles a little more than with the pair valve mod, but fewer exhaust fumes and I feel better with my CB not having that mod.
And I have the Staintune on mine.
