2007 rev summit 800 r compression

Guys what would these have stock at 3400 feet if I remember right it would be 120 - 125 stock?

Sounds about right

Compression? No. I have a newer short block in mine, measured it the other day it was 145 psi both sides.:d

Yes 120 and 125 is the exact same as my original motor in my 07. If it goes lower then be concerned. 07 was a year of many changes.

800 r only have a 13 to 1 head.

Where 800ho have a 14 to 1. That's where the extra compresion diff comes from.

Also that's y a 800 r works so well with a 14 to one head.
