|Diddyklr||If you plug the hose that the air induction system gets itís fresh air from you will no longer have any deceleration popping. I just did it to my bike. Itís only purpose is to make the bike emissions legal at the tail pipe.|

Technically, popping out the muffler is an 'After-Fire'. A 'Back-fire' is back thru the carb & air filter.
And I'll vote for a missing nut on the header pipe and a bad gasket because of the missing nut.

The gen2 KLRs (2008 and newer) have an automatic air injection system at the head that introduces some fresh air into the exhaust chamber in the head during throttle closed deceleration. This will cause some popping on deceleration (sounds a little like a Harley -just a little).
A leak in the exhaust system can cause backfiring. Check the bolts where the header pipe connects to the head and where the pipe pipe clamps to the muffler.
