The popping only happens during deceleration, normally when I'm at >6krpm and let go of the throttle entirely, it may pop some times. I thought that was backfiring?

A aftermarket air filter and de-snorkeling will not make the bike stop popping.
I thought KLEEN was only on the US carburettor version and the FI version doesn't have KLEEN?
