Backfire And Decel Pop

With my Meriden, true backfire is fairly common. Tickling (flooding) carbs on kickstarting sees to that. Often get flames out of carbs. Never get backfire once started.

Do get decel pop. Think it's the good type of 'backfire'. New silencers have larger exit hole, and possibly connection to downpipe isn't as air tight.

Speed Twin wouldn’t seem right without it.

None of the Bonneville family seem right without it.

I don’t get it on the Speedmaster.

I even got it on my Tiger 800 XC.

If you guys get out here you can ride the R3.

To me it’s a pretty classic sound, I like it.

I hope to make it out there in late summer. Depends on how Ilse is doing.

I have 3 old, carbureted Triumphs. They ALL pop on decel. When the carb butterfly closes, the mixture gets rich [carbs do not cut fuel flow when the butterfly closes like EFI does]. Just the nature of the beast. Love it and live with it. ...J.D.
