OK, so last week me and my employee went out on our 660's. That was last Sunday, his 660 was running fine when we came back home, we cleaned them and stored them to be used today again. now when we went to start his rappy, it wouldn't start, when we finally started it, it was spitting oil like crazy through the cranck case vent tube, we imagined it was bad piston rings so we went ahead and change those quickly, started the quad up, and it started nicely until we accelerated it, it started spitting oil out again. piston looked good, head looked good and cylinder looked good upon dismount. haven't taken compression test, should be getting the compression tool tomorrow. any ideas?
