Well I got my stuff back from Venom and am very excited to give it a try. I'm really at a bit of a loss for jetting though....

2004 YFZ450 @2000ft:

Modded ESR intake
42mm bored carb w/ rat stack
ported head
14:1 piston
07' yfz crank
White Bros. Exhaust

Any ballpark figures for jetting?

Side Note: I am running the YZF (Dirt Bike) Needle. I've never done so many engine mods at once to be honest so I was hoping to get a decent idea of whereabouts I should be.
