I've been led to believe that it's a 'normal' condition of our bikes and stock jetting. It's just a lean condition leading to a popping kinda backfire. Mine does it pretty regularly when I engine brake at the lower RPM's, never the higher ones. Specualating, that would indicate to me that Kawi jetted leaner at low RPM's for smog issues. If you do have a real backfire (like a gun shot) then there is definitely something wrong there. FWIW Karl
