thats a retarted statement??? ok thats why it came straight from kims mouth from K&T HUH!!!! theres other things to do to get more horsepower yes,, like case porting and so on,,, as far as your set up bkibina.. its evidently not doin so good.. i saw your video on ps and you got whipped out the whole by a 1980s something honda dirtbike,, so it proves my theory and i would change it.. if it was my set up is all.
