Sparks air filter - New jet?

[Crowdog]

I have my 450R jetted for full pipe, no air box lid and stock filter at 180 main jet. Just changed to a sparks filter. Should I jet up to 185?

I ride at Sand Mountain - 4500ft.

I have a full Sparks exhaust, no lid, and Sparks filter....my jetting is:

190 main jet
2 turns out on air-fuel mix screw

Runs great!

I was running stock filter and then switched to the Sparks filter, didnt have to change jetting.

Assuming you have a Sparks pipe, I wouldnt think you would have to rejet for the filter... But most people with the Sparks pipe are running a 190 main... I am and its working great for me...:macho
