Quick jetting question

[blwngp01]

Have an 04 with open airbox, k&n filter with outterwears. What jets should i go with and wheres the best place to get them from? Is there a writeup also? If i decide to put on a slip on exhaust do i need to rejet also?

if you are running everything stock with the airbox lid open. maybe bump the main jet one or two sizes richer. the stock main is a K148 i would maybe go 150 or 152.

when you do slip on exhaust you should rejet. also if you get a slip on you may as well spend 30 to 50 bucks and get a good airfilter too.

you can get individual keihin jets from jetsrus.com or C&D Racing.
or you can get a dynojet jet kit if you want, they give you a range from 145 or something like that to a 170 main.

when you get a slip on, you can go to that brand website and they should give you a recommended jetting spec for a starting point.
