I think I'm going to wig out! I have been trying to get this stumble out of the ole XR since i installed the Dynojet kit. I have the needle in the third postion from the top, #160 main, fuel screw out 2.75 turns, snorkel removed, K&N air filter, stock exhaust, and the slide drilled 5/32. I have a bad stumble from idle to full throttle. Also, i have read many posts of folks that have installed the same kit and can't keep the front wheel on the ground. My will lift the wheel in first only and that's with a 14t countersprocket!! Man I'm gonna freak out! I'm traveling to Montana this weekend and I need to get this thing working right. HELP PLEASE!!
