After a long ride yesterday I noticed that upon deceleration, my 650 is backfiring/making a popping noise. Does anyone else have this problem? If so, what was your remedy? Thanks in advance...

Dynojet says popping at decel is an exhaust air leak, or not enough gas (too lean) air screw setting.

Try opening up the air screws, unless you have reason to believe there is an exhaust leak.

I realize you may not have a dynojet, but the reasons are the same dynojet or not.

good luck.
