Tell me and be very honest no BS how good are the 800 Rotax engines. I am thinking of switching from my beloved Polaris's to the new Doo but I am skeptical about the engines. I have never been let down in 27 years with the Pol mills and I am talking about 10's of thousands of miles. What is their longevityand reliabilty? I have heard a lot of bad but mainly from Cat guys (which are the most brain washed people on the planet) they have a tendancy for lunching pistons. Thanks for your input.
