A friend of mine just picked up a used canadian 04 yz 450 and the guy he bought it from couldnt find the manual. We put on a full white bros. R series pipe and can not seem to get it to run right. We want to go back to the stock jetting and go from there. We know the guy before had a pipe on it and changed the jetting. So if any of you know what the the jetting is for an 04 yz canadian 450 that would help us out lots, thanks.
