I just finished the BBR 120 kit on my wifes xr100 and the sucker wont idle It will start if I give it 1/8 to 1/4 throttle and run fine untill I let the throttle go. I did notice I had no spark and wiggled some wires on the harness and it made a spark. So how do I test the coil? I have a stock control unit that I tried and it didnt change anything. I have a tryed a 38 pilot jet and a 48 both brand new and adjusted the air screw all over the place it made no difference. It also seems to get hot fast, might be wrong there. Any way someone give me another way to check something I am out of Ideas.
