I bought a 97 XC that someone stuck a 650 in it. It appears to have 38MM makuni's on it. It has no compression on #1 and #3 holes. Thinking maybe a head gasket. I was looking in DK for a gasket kit but there is 2 available for the 650's. Any Ideas?

one is for 88-92 650 carb, and the other is for 92-97 650 RXL. The gaskets are interchangeable

should be a serial # plate (sticker) somewhere on the motor,, maybe by the recoil,, have a polaris dealer run the # and they can tell you what year it is.

No compression means a lot more than a head gasket is wrong..

Take it apart and find out what is damaged first, and worry about the replacement parts after you know what needs replacing. [thumb]
