01 300ex Stock jetting

[ATC350X 85]

What are the stock jet sizes and needle position for an 01 300ex? I am picking one up on Wednesday and it is a hard starter. I think it needs to go up one or 2 sizes on the pilot. It has a white bros full exhaust and a k&n filter. I know it has been jetted but im not sure how well it was done.

i wanna say that 122 is the stock main, something in the 20's for the pilot and like 4 clips down on the needle.

The stock pilot jet is a 38 keihin. A 40 or 42 should help cold starts

122 is the stock main, and the stock pilot is 38. I experimented with a 40 pilot in my 330ex, and I always hated it. I changed back to stock size. Stock should be good for whatever you are doing. 300's are very cold blooded, you're best off just using the choke.
