I cut the baffles from my 2015 883 iron, I was going to make some lollipops for my pipes...will they help at all with decel pop? Also while i am cruising in town it sounds like I have a misfire, but I am not throwing any lights or codes, will that help at all? Or will the TTI from DK Customs help at all? Thank you.

 

If it were me, I would just get the TTIs from DK Customs. I use them on my Road King, and they work great. DK's have figured out the details and sizing so you don't have to.

 

Do they help with the decel pop and will the minimize my popping while cruising at lower speeds?

 

DK Custom's TTIs helped but did not get rid of my decel popping. Jamie from Fuelmoto tweaked my Powervision tune to get rid of the popping.

Do you not have a tuner? If you pulled your baffles, TTIs should help tremendously with your low to mid range and should reduce (and maybe eliminate) your decel popping.

 

I do not have a tuner...yet. going to stage 1 the bike over winter with all vance and hines. Plan on putting the vance and hine fuelpak fp3 on. Dealership said with just removing the baffles I shouldn't really need a tune, said yes it would help but only time I'd really need a tune is if I do a full exhaust and air cleaner. The decel pop doeant bother me as much as the popping I get while I am just cruising down the road. Anything above 45 it doesnt really do it. I did pull the plugs, just a little white on the tip but its not running lean enough to really concern me.

 

 

Decel pop and cruise farts indicate a lean condition. Lolly pops or TTIs help gain back power you lost after removing baffles.

 

I agree.

With open pipes, decel pop is common, and does not damage your engine.

HOWEVER, if you are getting any farts, pops, misfire when there is throttle applied, that is indicative of a tune in need of help.

Decel pop alone is not so much a matter of a good tune vs. a bad tune, but more a matter of exhaust configuration. Decel pop is Not indicative of a bad performance tune, only that the tuner did not know that you wanted it tuned out for your ears pleasure...or that they did not know how to tune the decel pop out.

Decel popping does Not damage your engine...it is simply unburnt fuel that is burning in the exhaust tract after exiting the engine.

Decel popping occurs when one of two things are present.

1. The bike is so lean the exhaust is superheated and is burning the unburnt fuel that is in the pipes (there is always some unburnt fuel in the pipes no matter how lean). This is very rare.

2. The AFR IN THE pipes is just right to burn the unburnt fuel. This is quite a common occurrence when free flowing pipes are installed (whether or not a free flow A/C is installed). It can also occur if there is an exhaust leak that is introducing extra air into the exhaust tract.

Also, check for intake leaks at the intake manifold/heads.

Another way to change the AFR IN THE Pipes is to install Thunder Torque Inserts. Not only will these reduce/eliminate decel pop, they will give a good boost in torque in the low and mid range. See details & dyno charts HERE.

It is absolutely possible for a tuner and someone who knows how to use it to tune the decel pop out.

HOWEVER, the methods used to tune the decel pop out of very open pipes are almost always at the sacrifice of performance and/or MPG.

An open pipe with the best performance tune is almost always going to have some decel pop.

To get it tuned out, without just dumping gas in it, you will need to find a tuner that understands how to do it...it is possible.

 

The decel pop isnt as bad as the crushing farting sounds I'm getting, is that bad for the bike or is that like you said extra fuel burning up in the exhaust? Just dont want to wreck my bike and I'd like it to sound decent.
