adding k&n and boysen pro seris w/ spacer 2 jet sizes?

[Outlawed Genetics]

like the tittle says im adding a k&n style high flow filter, boyesen pro series reeds and a reed spacer think going up 2 jet sizes will be enough?

its going on a pretty much stock 04 that currently has pro circuit pipe, and uni filter. pretty sure the reeds are stock.

You could start with two sizes up but I bet it will only need to go one size up...you really never know until you try though. Heck, you may be able to just change the needle position..... Read the pamphlet with the boyesen reeds, they talk about the jetting in there.

Have you already jetted it for pipe if you have 2 sizes will be a good starting point
if you havent jetted it for pipe you will go up quite a few sies i have the similar combo i just have 30mm carb and am running idle jet 45 main jet 160 hope this helps
