300ex jetting

[robbo1]

Hey...im new to the site and had a question about jetting on a 2003 300 ex. I have a Yoshi slip on pipe and KnN filter and am needing a safe start point for both jets. I know how to read plugs and where to install the jets...but as far as needle hight and what to look for in idle and WOT im a bit lost...any feedback is greatly appreciated THANX...oh yeah i live in ct and in a river valley so its pretty low altitude...if that helps:huh

I bought a Dynojet kit for my 300 and followed the instructions and mine runs awesome. Simple with no guess work with mine anyway. They tell you which one for elevation also. Just remember the stock jet sizes and the Dynojet sizes don't corospond. The numbers are about 13 off from each other.:macho
