2007 800R engine compression?

[Summitstef]

Is this right?? After a ride today I did a compression test on my engine just for $hits and giggles. I had 90 pounds on both the PTO and MAG. The sled pulls like a tank and the plugs were chocolate. The engine has just over 900 miles (1500kms). What gives?? Some answers please!!

Sorry to here that. Contact Big John at www.sledheadracing.com in Min. John will set you up. I sent my head to him last year. It needs to be milled 10,000 to get your compression corrected. My 07 rips with his clutch kit & head mod. Again thanks John.

That seems low, but because each side is the same I don't think you have a problem neccasarily. ALthough I live at 8600 feet and get about 117-119 on mine.
