well the xx has ran great since i bought it over a year ago, but like most everyone else i wanted more power and speed.. i didnt have enough for the big three so i got the EHS lid and programmer and got the special spark plug. well now it runs great but if you rev it up half way or above it will smoke. comes out black at first then goes to a greyish/white smoke as its idling down. i know the programmer doesnt actually mess with timing- just fuel. so what is the deal? only had it on for bout 2 months now and rode 3-4 times. we don't ride it hard and i have the programmer set like its suppose to be. i even changed it up and down a few notches but no change. it doesnt smoke like that every time you rev it up but probably 1/3 of the time and doesn't smoke noticeable when riding....
so any advice or insight would be greatly appreciated. doing valve checks now. just praying the motor aint going bad.
