Hey wait....... I have a 1998 Polaris fuji 440 indy trail touring with 26,000 miles on it. Only replaced the spark plug caps and regular maintenance items. Still runs fine. Kids totaled it twice. Bought back from Insurance (1st time) and banged the dents out. My 350# plus brother in law uses it in Canada to pull his ice shanty to this day. He says it still runs great. I sold it to him with 12,600 mile on it back in 03 for $700.00, I also have a 2001 800 xcsp that has 16,800 miles on it. Replaced top end seals (look like black spagetti), anti freeze started coming out buy temp sensor. Nothing major. 3rd track all because of pulled studs. 2nd drive bearing thats it. So I think the 2 strokers have come along way. It's nice to see testosterone flying now and then. But none of this is helping answer the original question.
