things I have done to solve it,
changed tune on top from 3 out to 5 out and everything inbetween
changed tune on bottom from 3 out to 5 out and all in between
changed shimming to 2 silver 2 copper and stock shimming
changed pipe from go2047 to re-10
changed fuel line
changed plug from stock to OD 99 to mc59
took apart and sealed everything
changed clutch 3 times even to different brands
any ideas?? it runs good till I get to the top end then it sputters and pops and dies. like I said I went lean to fat on top..
any help would be great
