For some reason when I shut down my AlpineRX1 it backfires out the exhaust. Any ideas ?

Hot exhaust, unburned fuel vapors pumping out the exhaust valve when the spark is killed, POP!

yeah, thats exactly what mine did when i had it running to rich, everytime it was nice and hot and I shut it off it kinda sounded like a .22 going off inside my exhaust.

Pull the plugs and check the color of them, post a picture if you can. It sounds like you may be running a little rich.

mine does the same unless you let it idle for 15-20 seconds before shutting it off. It is rich at WOT according to the wideband.

It is loading up when when I am riding at 1/4 throttle and then cleans out when I run it hard. I will pull the carbs when I get time and see if a choke is sticking or a float is sticking.
