Jetting for Shearer Exhuast

[aas5f6]

I just purchased a shearer exhaust kit over the internet. As of right now, I am all stock. I will be getting a uni air filter soon with the air box lid removed. Could anybody suggest where to start with jetting? I know its subjective according to temperature and altitude and other factors. I am just looking for a starting point.

i would say 280 would be a good starting point

I would start high with like a 320. yes it will be richer but you can just go down from there instead of going up and down trying to perfect it.

i believe the toomey kit, with the uni and airbox vents comes with a 310,
