Jetting question

[theshiz]

i have an '05 450 with an HRC kit (modified airbox lid, K&N air filter, and cam) and just recently bought an HMF slip on, and i was wondering if anyone knew the best jetting solution for that setup, thanks.

I would start with a #50 pilot, 185 main and the needle clip one down from the middle.

Pretty much the standard starting point for a piped 05.
