jetting

[2001EX]

I was wondering what a good starting point would be for my main jet. I live in Oklahoma. I have a stock pipe with baffle by the spark arrester removed. The airbox lid is off and the snorkle tube is removed and plugged. It also has a unifilter on it. The reason I'm wondering is because I bought it used and just rebuilt the topend and want to make sure the jetting is close. thanks for any reply.

I"d go up 2 sizes on the main jet.. Should be pretty close...if not it'll be running rich I would think and that's better than lean..
