My 2008 Joyner MV 800 seems to be running lean. It is fuel injected and it runs cleanly from start to the rev limiter, but it makes a series of popping sounds when I take my foot off the gas.
It there an aftermarket chip, or a reprograming tool available to fix this condition?
Thanks. _________________ 2008 Mini Viper 800

is it like a back fire? if so check for air leaks in exhaust system _________________ 06 joyner 250 sand viper,red metallic..blue clutch spring 17 gram sliders
