I just installed the boyesen rad valve on my 96 kdx200 and when I started the bike it revved like crazy. So I adjusted the idle until it seemed somewhat normal and wouldn't stall when I put the choke back in. Couple things: it says to go 2-4 sizes leaner main jet, I don't know what size I have now, so how do I know if I need to go leaner?? Should I adjust the air screw?
I bought the bike from someone who put an FMF fatty pipe and silencer on it. But I don't know if he rejetted or did anything else.
