I have an o4 trx 450r and it has the hrc kit and i also have the lrd pro 4 full system on it what jetting comes with the hrc kit and what is the stock jetting if it is dfferent

hrc jetting: 185 mainjet, hrc needle in 3rd clip position


stock jetting: 118 mainjet, stock needle in 3rd clip position


i also turned the fuel screw out a 1/2 turn or so after the hrc kit install. remember, the main jetting differences is from the air box lid in the hrc kit, not necessarily from the cam itself.
