The 1997 model Polaris XC (Cross Country) 600 is a discontinued snowmobile made by Polaris Industries, a leading recreational vehicle manufacturer. The 1997 XC 600 was one of the earlier models of the snowmobile preceding the modern 2011 600 IQ and other models. Information about the XC 600 is still available if you are considering a purchase or are making repairs.The 760 stock cylinder porting is designed to run the 760 huge volume exhaust pipe and no way can you fit it in the Superjet. The more aggressive 760 cylinder is more like a heavy ported 61X cylinder for closed course racing, a loss in bottom end and big increase in mid to top power.
If you build the 760 like a race setup then the more aggressive porting will make really good power even for freestyle, but most don’t want total loss ignitions, race gas compression, expensive custom race carbs and so on…
The port location is a little different and SHOULD be port matched to be correct, bolt pattern is the same, but the 760’s use the 10mm bolts instead of 8mm bolts to support the huge stock exhaust from the 760 engine.
No big deal there, as you just screw in 8mm X 1.25 helicoils into the threaded holes as they are the same 1.25 thread pitch.
As far as sleeve’s go…yes you have about .080 more in bore size with the stock 760 sleeves.
