Just wondering!!!

[450rdominator]

hey just curious what jets everyone is running on there 06 450r w/rossier exhaust!!!

I have the hrc needle 4th clip and the hrc leak jet Im not sure what size it is, 172 main, 45 pilot, 2 1/2 turns out on the air screw. It works perfect, couldnt ask for any better.

if i was running the stock pistons would that 172 work for me or should i use like a 168 or 170 main????

a piston does effect jetting as a higher compression piston will pull harder signaling on a carb jet circuits...



Hope this helps.
