16 KX 450 excessive deceleration popping. Any suggestions??? I'm coming off of a 12 KX450 that did not exhibit this problem. I've had my 16 for about 4 months and it drives me crazy. The bike runs great otherwise. I've tried replacing the copper header/cylinder gasket, using fresh fuel, clean air filters, etc. I know this is a trait of the 16, but I wonder if anyone has a solution for clearing it up? I've had it remapped by Tokyo Mods and it has helped a little, but not much. Any input is appreciated. Thanks!!!

If there is no exhaust leak, then you need to richen the idle mixture via whatever tuner you are using.

Make sure you don't have some type of intake air leak.

Adjust your valves. It fixes this same issue on my kx every time.

Pro Circuit exhaust fixed mine.
