I just recently had my engine rebuilt.... .30 overboar and ported and polished. I was just wondering if I had to adjust my main jets or pilot jets? I will be riding in below freezing temps and currently have my jetting set at 420 mains with 29 pilots....does this sound right to you? Also, a friend of mine just bought some 28 PWK carbs for his shee, and was wondering if he had to adjust his jets for his new carbs? Please Help. Thanks.
