Hello everybody
I have 2014 streetglide with 4"rinehart slip ons,everything else is complete stock.
I notice I get a slight decel pop when I give the throttle a slight to medium "blip".
But when I give the throttle a stronger touch, I do not get any decel pop.

Can anyone explain why it does that? Is it normal? Ways to solve the problem?

Thank you for your time.

 

tuning.

 

after checking for exhaust leaks.

 

Start saving your money:-) It's caused by combustion of an unburnt fuel mixture in your exhaust. Usually can be cured by richening the a/f ratio which will result in a mixture that is too rich to have a secondary ignition in the exhaust system. Live with it or get a tuner that will let you fine tune the a/f ratio. BTW, it's not detrimental to the bike. Just a noise.

could be the exhaust flow through the rt side is sucking air in from the left.
added oxygen is helping some unburned fuel to burn in the pipe

( it's really hard to tell from here)

if your fuel MPG is good, then i wouldn't worry about it, if you blow back smoke and get 32 MPG, then you certainly have a tuning concern.

stuff like this was nt so much a concern 0n a carbed bike as letting off the throttle and the resulting high manifold pressure would often go over-rich momentarily.

really good on my FXR for letting traffic know I'm coming up the middle

My 14 sgs was the same way bone stock, added power dual and twin slash pipes, stage one down load, still was the same...added cams tuner and dyno and it went away. As others have said probably never cause an issue just sounds like crap.

 

Mine had some decal popping with the original exhaust, it's just a lot more subtle. The EPA loves when new Harleys run lean. Definitely check for exhaust leaks though.

does it when I roll "off" quickly .....I love it! Some may think its an issue. It doesn't happen all the time......my Deluxe did it quite often for over 6 years and it was music to my ear

 

I have a 08 Ultra and it did it with the factory mufflers and is no different with the Rhinehart that I put on, just a little louder since they are louder.
