hmf sport series slip on jetting?

[balls_350]

i just got my hmf sport series slip on exhaust for my 04 450r, and i was wondering if anybody had a general idea on what size jet i needed and if i needed to adjust my air fuel mixture screw, it has a stock jet in it now, stock headpipe and stock intake.

Thanks: Trent

I didn't even open these, but there are 49 pages of jetting threads. Use the SEARCH button it is a wonderful thing.
