Bonneville America Forums Forums Technical Forums Exhaust Bubs exhaust- decel popping/ backfiring

I have the Bubs, and have a problem with excessive deceleration backfiring and popping. Has anybody experienced this, and what size replacement jets are needed, and where can you buy them?

I'm running 130 main jets with 3.5 turns on the screws with my Bub Dresser Dogs. Get minimal popping on decel. Good luck just need to play with it to find what works best for you. Check out Dinguas site very helpful, it provides step by step instructions on many common tasks. He's saved my neck that's for certain. Ride Safe

I have the Bub Dresser Dogs an running stock jets. Everytime I think about rejetting my bike is running so good I just forget about it.

I have the Bubs Slash Cuts with stock jetting but removed the AI system. I had to turn the mixture screws 3 turns out and only have minimal popping on decelleration. It runs great and does not starve for fuel all the way to the red line.

Changing the jets did not do anything for mine. Turning the screws out about 3.5 turns minimized the popping. It still pops at low RPM, not a concern, I shift before then when possible.
