If you have no instructions for recommended jettings then I would check out their web-site or call em. If they do give you settings then it may still be off a little so you may have to go up or down a couple b/c not every machine is the same. :cool:

i went up one size on the main jet and it worked , i think it comes read to run with the stock jetting but im not sure, you should buy 1-5 sizes up on the main jet , try the highest one first, if it boggs down wen runing go one size down , keep doing this until it stops bogging

i moved up to a main jet wit my 250ex...works great
