450X Jetting Questions
Posted: Mon Nov 09, 2009 7:22 pm
Can anyone offer some jetting advise?
I have a 450X with stage 2 Hot Cam, oversized SS valvs, pro circuit exhaust, air box mods. The current jets are 170 main / 45 pilot. It was running rich, so I changed the needle from notch for from top to notch 3 (dropping it further into the jet, and I changed the fuel/air screw in from 2.25 turns out to 1.5 turns out. I'm hoping this will lean it out, but I am wondering if I should be changing the jetting while I'm at it.
