Seized my 800 over the week in the U.P. Anyone heard of any problems with these ? I have been a die-hard Ski-Doo man for years.....but this will test my will. What ever happened to the bullett proof Rotaxs' of old ? I am starting to think 4 stroke (RX-1)...but i can't bring myself to think about changing to something other than Ski-Doo.
