I have a 06 rxp sc. And took it out and it ran good for about 20 min then it just stoped running. It would turn over but no crank. So took it to dealer and they said it jumped timeing. There is a plastic cover on the timeing chain side of head that they said broke and caused it to jump timeing. The stuff has been replaced and is running again but with a nice price tag. Of over 1800 in parts and labor. But my question is what would have make the plastic cover break and do what it did? It looked like it was melted. A bit. Ski only has 25 hours on it.
