hey guys...need your thoughts...I put a Lexx pipe on my bike, and it also has a Bills header pipe (full exhaust now). It starts and idles fine, but she is popping on a little on decel, and I have seen flames come out of the exhaust ! The flames did not start until I added the pipe. This is with a 52 pilot (stock was 45). The main is 165 stock, I am bumping it to a 170. I have not checked the pilot screw, so I may start out at 1.5 turns out. Any suggestions ?
