Help me jet!

[MIA450R]

Guys-
I have a stock '04 TRX450R with the FULL HRC kit installed.

I am going to add a K&N air filter with Outerwear....

Should I change the jet? (currently running the HRC-cam, HRC-kit's jet, HRC-airbox lid and stock exhaust with HRC-endcap)

thanks...

HRC jetting should be about right. but if you are real worried about being to lean bump up the main jet no more than 5.

Ya the 185k that comes with the HRC kit should be fine.
