They all do that Sir. Some people even like it.

HTH

 

My 07 1200GSA pops less since I fitted decat headers and an Akro can and I am gutted

 

My 2008 GS popped as well until I synchronized the throttle bodies, Now hardly any popping at all.

 

Poppping Exhaust During Deceleration

Good to know most GSA's do...my 2010 does.

 

I think it's a Boxer hexhead thang...

I owned '05 and '06 RT's and now an '08 GSA. I think they all have the hexhead motor and they all 'popped' on decel.

 

My 08 GS pops on decel at around 4K-3.5K rpm

 

My 2010 GSA belches like hell when down shift from 2nd into 1st and especially when I let off the throttle in first. I think it sounds great!

 

Recent owner of a 2012 GS1200 Rallye Edition. Mine does the same thing, pops and gurgles on deceleration. I was concerned as I am new to owning GS1200's but with these responses, I am less worried now. However, I do not get how anyone actually "likes" that sound? Spitting and backfiring elicits nothing but "embarrassment" as I am positive people around me are thinking "wow that dude needs to get that motor looked at". I am most definitely NOT A FAN...

 

In my experience all of my Hexheads popped on decel to some degree. OEM exhaust will give the illusion that its less prevalent but only because the OEM muffler does a really good job at muffling sound.

 

Your bike is fine. I have an Akropovic exhaust and it gives a nice burble and crack when I decelerate.
