Default Compression on '14 600 RMK

I read 80 on both sides when I brought it home from the dealer... I know compression will increase as the rings seat but compared to my '07 600 (4200 miles) reading 120 it seems pretty low to me. Did polaris lower compression on these newer motors, possibly for EPA reasons? I'm at 3300'. I wish I had checked compression on the '07 when I brought home.... I will check the '14 again when the breakin premix is burnt out of it. Has anyone else checked the compression on the new 600's ??

Should at least have 120 stock. it won't even run with 80, your tester is wrong or broke hold throttle wide open and pull it over till the needle stops moving

My 13 600 had between 110-115 brand new at 4500 ft. With the par 13.6 head it was around 125. You should be around 115 at your elevation.
