I change the stock exhaust cam with an 03 auto decomp cam. I also change the stock fuel needle adjustment to an easy adjust fuel needle. The bike fires up after a couple kick and idles but it seems kind of rough. I have the fuel needle adjusted out 1 1/2 turns. I let it warm up and crank the throttle a couple of times and the idle seems to hang. When it comes back down it idles rough and wants to stall.
