Kawi Performance has some great tips on how to keep your Kawasaki Ultra longer lasting and running great. They recommend refreshing your engine at about 250 hours due the supercharger wearing out. This will prevent engine failure. Kawi Performance has performed extensive testing and concluded that the oil pump is the biggest wear and with it being the heart of the engine, you must take care of it by not only rebuilding the 250/260 Ultra supercharger, but also replacing all the bearings and seals. Pump bearings should be replaced seasonally. Another major proactive measure is to change the oil often on your Ultra.
Kawi Performance recommends every 10 hours on a race machine and every 15 hours on a PWC used for recreational riding. Heat and blow by are hard on race machine and the oil burns fast. This degrades the oils properties and lessens its effectiveness as a lubricant. Sludge will build up as well, making your engine work harder and eventually cause engine failure.
The oil you use is determined by your climate and water temperatures. 10W-40 is best for cold climates where the water temperature doesn’t go above 70F. 15W-50 and 20W-50 are best for warmer climates with water in the 80F and higher range. This oil has a thicker viscosity and can handle the heat better. Fully synthetic oil is recommended with high anti-wear additives to keep your watercraft well-oiled for years to come. Check out the Kawi Performance website for all the details and more on how to keep your machine running smooth so you can stay on the water longer.
