Stock compression ratio on 07 800r?

[moondoo]

What is the stock compression ratio for the 07 800R? I've heard it's pretty low.

12.15 to 1

I heard they lowered it for the 08' 800R. Is that true and what is the new comp. ratio?

I checked my 07 XRS last year and the compression was 130 to 135. My 04 800HO was 150.

They raised it for '08 but I don't recall the ratio.

Same as 07 12.15 to 1

They did not change it because it meets EPA regs at that number. If they raise the CR then it does not pass.
