hrc kit

[poke99]

Hi all, I just bought a used 04 450r that is all stock except a Pro Circuit T-4 slip on. It has been jetted for the T-4 and the bike runs great. The first thing I am going to do is drop the front sprocket to a 13 tooth (they are stock at 14 correct?).
My question is if I was to buy an HRC kit for this bike will the jetting that comes with the kit be OK for the T-4 that is on the bike? Thanks all

Well, will the jetting you get with the HRC power up kit work with the T-4 slip on? Thanks

it should but you will need to go out and buy all the pilot jets from 48-55 and find out which works better. because the HRC kit does not come with a different pilot. and you may need to go to a 190 or a 195 on main. HRC is a 185 Main. The needle on 3rd clip will work fine for ya.
