Due to cost constraints last year I wound up using Wiesco pistons(coated) and rings in my rebuild of my SRX.I was a bit uneasy about the ides of using these but was assured that they would be just fine as long as I let the sled warm up lots before riding it,I always do anyway.Anyway what kind of mileage should I expect out of the rings before they need replacing?Surley the pistons would out last the rings so I would'nt have to do the whole set,not that I have anywhere near the milage on the engine from just one season of use I'm just curious.
