An oil change is one of the few maintenance jobs that need to be done on a 4-stroke engine, but it's vitally important. Last winter when it was time to have the first oil change done on our two 2009 Nytro demo sleds we took them down to Yamaha's snow division headquarters in Pleasant Prairie, Wis., to be coached by a professional. We were led through the easy job by one of Yamaha's top all-star mechanics (Nick Leikness) who gave us the right tips on the procedure from top to bottom.
It's important to note that the first oil change and filter replacement on the Nytro based sleds should be done at the 500-mile mark and then the oil changed every 2,500 miles thereafter. The second filter change is only needed at 12,000 miles after the initial break-in. Yes, you heard correctly 12K! No wonder so many people have been drawn to the 4-stroke side of the playground.
