Try running it with the side cover off and see if the variator is getting stuck or not coming out at the right time. I put a simo pipe after having a stock bike with a 13mm carb that ran and idled great..I went up 2 jet sizes with the big simo circuit pipe. Either way I didnt have to jump that high but then again someone else had installed the 13mm carb, but it was running great before that. This leads me to believe that something is up with your variator. Does it pull really hard off the line, or did it before you messed with it?
