650/X-2 sbn 44 baseline jets

[waterbox]

Just picked up a 44 and my intake mani is in the mail. Just curious if someone can give me a good starting point for jetting. Motor is stock 650sx with a prop. Thanks

I have a 650 with westcoast manifolds, west coast pipe and a 9/17 skat and I run 115 low 145 high 2.0 n/s
Ran 40:1 all season. Setup ran perfect, no bogging and kept the plugs a little wet

Thanks parky, I'll start with that. Should be too rich if anything, to stay on the safe side.
