I purchased a 1998 polaris xc 700 this past season. It ran great until the last mile of a ride in late
feb. It started to leak coolant from the cyl. base gasket( is this a common problem on these?). So I
took the motor apart to replace the gaskets and o-rings and when it was apart I noticed that the cylinders were two different part numbers one was a 5131824 and the other was a 5131220. The only difference that I can see is the exhaust port is oval on one and more rectangle on the other. Now can I run it this way or should I match the two cyl. the other problem I found that the 824 cyl is cracked
between the large and the small exhaust ports. I found a place in Fon du lac that can repair the cracks and recoat the cylinder for $250 or should I just look for a good 220 cyl ? I would also like to replace the pistons I was leaning towards OEM pistons any other recommendations would be appreciated.
thanks, Mike
