Another jetting question.....sorry

[dodgeram]

I am installing a full yoshimura exhasut system with a hot cams stage2 cam. I currently run a K&N airfilter with the airbox lid removed and the hrc endcap. I jetted my bike for that and all I did was put a 175 mj in. Bike runs perfect, do you think with the new mods I will have to mess with the needle, or pilot jets. Alos I was thinking of starting with a 185 mj and going from there.:confused:

I have the HRC cam and Sparks exhaust and filter. I run 185 main and needle from HRC kit. Tried 190 main and was too rich. Hope this helps.
