ADA Dome Size for 84mm 701 Big Bore

[x2skier]

What ADA domes (pump gas) are ideal for a ported 701 big bore with 84mm pistons? I assume 760 domes but what cc? Sea level riding.

What compression fo you get?

I'd use 35cc domes depending on your pipe and ignition for pump gas.

According to ADA's web site, those 35 cc will yield 200 lbs and would require race gas (105 oct.)?! I guess you need to tell us more about your setup! I guess the porting plays a major role in this as well. I got the 40 cc, I run a dry pipe and haven't tried it yet. I gather I could always go down in cc's if needed.

Depending on porting, 35cc domes may be borderline too much for pumpgas.
I run 35's in my Jetworks 760, but I am mixing Pumpgas with Avgas. 3:2
