Hi guys.. could someone please advise me. I put a fmf 4.1 slipon on my new 09 yz450f. Am i gonna need to change the main and needle clip position? I was thinking of using the 165 main that came in the bag of goodies, also moving the clip one position to the 4th position...any real world advise would be helpful..thanks.

When I click the link it takes me to post #6, and I can scroll up and down. Anyone else have a problem with that?

If you can't get it to work for you for some reason, try this:

It's the '08-'09 page of the jetting sticky on the index page.
