I'm getting ready to do some jetting on my buddies Raptor 350. I would like an idea of where to start. I haven't seen much in print on this bike yet so I thought I would pull from other's experiences here.

Here's what he has.

GYT-R full system.
Pro Design intake w/ K&N and Outerwear.
Air box lid removed.

Elevation approx 900'

We are in the south so winters won't be bad. Temps in the 40-50 range will be an average winter day.

Thanks in advance,

Buck
