Seeing if any of you guys might have a jet ski or two laying around. Was wondering what kind of oil you guys use. I have been using MasterPro 2-Cycle Sport from O'Reilly. The motor (787) seems to run fine on the oil, but every other trip out, I clean the RAVE valves because they want to start sticking and have buildup on them. Seeing if you guys have any recommendations other than the Rotax synthetic oil that is EXPENSIVE as [censored]! Also, it has a little over 90 hours on it. Thanks.
