Do you use your choke? I completely removed the choke assy. That includes the butterfly inside, plugged off the hole with sealer, and used a K&N. It wanted more gas. I was able to run richer main jets, pilot jets. I bet with a pipe that would really make a difference. More air + more fuel = more power.
