I was looking at another site and the guy who owns JDjetting (www.jdjetting.com) and he said with stock needle to go with 175-180 main and 45 pilot and with GYTR needle to go with 165-170 main and 45 pilot. You can get his jetting kit from his website for around $65.


By the way, what pipe did you end up going with?
