Hey guys, im getting my pro-x 350 motor back today, was wondering if anyone had an idea what i should start out with on the jetting, its a pro-x 350 kit with trx9 porting, long rod motor, 40.5 kiehin carb, trx 11 stardard mount pipe, 2001 cr 250 ingnation, esr elimator kit with uni air filter, not sure what the pilot and neddle r, what ever esr sends them with, i live at 7000 feet, I had an Esr 330 bolt on with the same set up and it ran a 180 main jet up here at 7000 feet and 195 at glamis, Ive heard that the esr kits run a lot leaner then the pro x so was wondering if i should stay with the same jets from the 330 kit.

well first see which pilot and needle are in it sometimes mistakes happen and wrong jets get shipped.
but my 330 and 443 both using a 42mm carb are running 185 mains and 52-55 pilots different needle in both though.
