Deceleration exhaust crackle

Recommended Posts

A stock bike should make nearly no noise on Decel. The S and SM (and most of the E's these days) all have a decel carb circuit that, along with the stock, unmodified muffler, do an excellent job of quenching decel pops. Though I imagine if you forced the bike into over rev you might get a few mild ones. I would not be too concerned. You should hear my SM with the uncorked Yosh Ti on decel. - 'Rappitty pap-pap-pap!'

Mine is brand new (only 110 miles) and does the same thing. It surges sometimes when at a constant steady throttle. What should we look at it, it take it back to the dealer and have them look at it?

Sounds like it sat in the showroom for a while after they ran it.the pilot circuit is parcially clogged

When I'm high in the revs and come off the throttle my exhaust crackles

 Try tightening the bolt/clamp where the headpipe meets the muffler, you could have an exhaust leak

i tried the header pipe, it was tight at the engine block.  on my bike, a 2017, there is no bolt/clamp where the head pipe meets the muffler.  it's all welded.

 

so do i really have to tear into the carb?  is this something the dealer should take care of?

 I was answering the OPs post, your problem of surging sounds carb related. Try a strong batch of seafoam in your gas tank, it's worth a try, otherwise, especially if it's under warranty, take it back to the dealer
