I just installed a Two Bros. V.A.L.E. black series and installed the map for it provided on the PCV website. I am still getting a LOT of popping on decel, and after riding it a few times, when I come to a stop and turn off the bike I noticed that the exhaust has been smoking from the end and it smells almost like burning plastic or something, just an awful smell. What is causing this?
