Here's the technique for jetting.

with just a slip-on, you should be fine to just shim the needles out a little. Desnorkel while you're at it so you only have to adjust your jetting once. But still get a pair of jets that are 1 step larger than stock, and do some WOT tests to make sure the top end still feels good before you mess with the needles.

Thanks for the links! My phone cant search for some odd reason. Will look into it.
