[WILD_KYLE]

hahaha whys that?

[WILD_KYLE]

so no one knows what cc i need to run for pump gas and what kind of domes i need to get? wow

[wetjet701]

I'd go 38cc or 40 depending on cylinder porting if it's a freestyle port then go for 35cc domes. Really all the info on your motor would help

[WILD_KYLE]

its race porting
superstock ski

[wetjet701]

I'd go 40cc because race porting raises compression and I'm running 175psi on a stock 760 with 38cc domes.

i have alot of domes but they rase it to like 210 and uncut ones i got i think 26s 28s 36s
