What size main for a HRC kit and K&N

[400ex4ever]

I am getting ready to have the HRC kit installed and am curious if the new 185 main jet is enough if I change the filter to a K&N? I am thinking I will prbably need a 190. What jet is anyone running that is also rumming a K&N? I just a little above sea level.

I don't have any experience with this but I would say stay with the 185 unless you change exhaust too. Or what about adjusting the needle?

Yeah I was thinking maybe just the needle too, but I know I have seen some user signatures saying they are running a K&N, with a 190. I think they have a full exhaust system but I am not sure.

and i have stock needle until the performance needle is available.I also cut a hole on the back top of my air box lid until i get the HRC lid and splash guard.
