No way skidoo would say their new engine needs a rebuild at 7500. That would not be an improvement over current etecs.
Likely rave valve cleaning, spark plug change, clutches cleaned and inspected/adjust track and belt deflection, chaincase oil/chain adjusted, grease all fittings....stuff like that
Yeah I thought the same of the 850.... 7500 miles not a big improvement if any but no specfic details were listed just stated 7500 miles was some sort of milestone for the engine that Doo listed according to ST. I thought maybe you knew more or were aware of the 850 write up in Snowtech's first issue this season. I have great hope for a super robust 850 so I'm always reading about it when I can.
