I have a 98 RMK 600 that is in need of a new top end, and I was wondering if Weisco pistons or other after market kits are more or less reliable. I am not as concerned with extra power, just stock reliability. If there is such a thing as great reliability and extra performance that would be great, but cost is a major factor. I want to do this pretty cheap as this is an old sled. It seems to me that I am looking at about 250.00 with a piston kit and gaskets? If anyone has any good places to get a great price on parts that would be great.
