Piston gone - Sledbunnyracing

[SLEDBUNNYRACING]

2007 Rev with over 6000 k on it.
Last weekend on McBride at km 7 it it stopped running. Pulled a plug and a cylinder was dead.
Pulled it apart and the rings were welded to one of the pistons.
Rebuild time.
It's not about the cost or the hassle, it's about the time I get to spend with my son.

Ordered my replacement 800 Rev Jugs, Postons etc. Should arrive at Sherwood Park Service Mon/Tue. Install (time is always an issue) completed by next weekend.
Thanks to Summitric for sourcing/sharing where he got his same parts for rebuild at Christmas.
Sooo it looks like I should be riding on our trip Mid Apr.

Ah, Pistonbroke.

 

[camarogreg]

good luck with the rebuild! Any idea if the oil flow stopped???

 

[kootenaycat]

Kind of looks like a "4 corner" sieze, did it get rode hard from the parking lot with little to no warm up by any chance?

 

[SLEDBUNNYRACING]

Ah, Pistonbroke.

Your handle tells the whole story....lol

Nope, just age.

Lots of warm up, slow ride to pay for trail pass, slow start.
6000 km on motor so it was time.

You told me your flow wasn't affected by age...

Those pistons did not die from old age. Something went wrong. Either overheated or no oil. New pistons won't last long if you don't figure out what caused the problem.

 

[Summitric]

My bet would be overheated... Can almost see the 4 corner burn, which is usually insufficient warm up, or overheated .... Stuck termostat or broken thermostat like Justin's, would be my bet

Guess I'll be changing the thermostat as well.

Check your oil supply lines and maybe replace the oil filter as well, to be on the safe side? Be sure to check oil pump adjustment when together

 

[Summitric]

P.s. I think your shop manual is at my place still?
