What size domes should i use?

[BansheeBanditBrian]

I recentley bored out .20 over stock and bought a noss head, fmf sst exhaust, everything else is pretty much stock.

I ride at a couple different places any where from 6,000 to 8,000 feet above sea level. What size domes should i buy?

I guess my question is what's the difference between 17cc and 21cc?

Thanks

What's your compression? I'm at 5000 and run 19s on pump gas you could probally get away with 17s on pump that high smaller dome raises compression.

6K-8K elevation, you would be fine running 18cc domes on pump gas. You may be able to get away with some 17cc domes at that elevation, just depends on your compression. IMO anything around 165psi and up should run race fuel.

whats ur compression at 06?

 

I run right around 150psi or so. I havent checked it in awhile though. I'm running 19cc domes right now. At our elevation I know people even run 18's on pump. But I wanted to be on the safe side so I stuck with 19's.

Ya I'm only at 120 with 19s but waiting on part for my top end should be in today. Pistons and cylinders are still stock just rings gummed up for sitting for a year and half so hopefully new set of rings and ill be flying

I'm about 150 compression with the stock head.

What cc is the stock head?
