What has anyone checked the PSI on thier 650 or 700 Prairie/Brute force motor? I have an AC650 V2 and I am only getting 80 PSI, this sounds real low from my experience with sleds in the 140-150 PSI range. This was tested with a Craftsman guage so it should be somewhat accurate.

Thanks

 

its hard to tell because that motor has decompression built into the cams that keep the compression down for easy starts.

 

There is alot more performance coming from a sled. You should have alot higher reading out of a sled than an ATV

 

I pulled out the Shop manual from my old Prairie 650, it clearly says 47 - 81 PSI is the normal range, so I guess I am OK
