2010-2013 Camhead Oil Thermostat Failure Question

[radar41]

Has anyone had an oil thermostat fail and cause excess engine temp, resulting in the cam chain tensioners deforming causing rough running or engine failure on the Camhead (2010-2013) engines.

Your oil cooler radiator should be warm/hot when the engine reaches operating temperature.

Thanks,

Are you sure it was a thermostat failure? Did it read hot on the gauge cluster?

The reason I ask is because some of those twin cam engines burned a LOT of oil from the factory, and I wouldn’t be surprised if some were run very low on oil as a result. That could certainly damage engine internals.

Have you owned the bike since new?

Camper,

My 13 is fine. A friend with an independent shop has had two of the Camheads come in recently with this failure, i know of one more failure of this type. The two in the shop the oil thermostat was NOT opening, I.E., the oil cooler did NOT get warm when the engine reached operating temp. This (Oil cooler Thermostat not opening) caused the chain rails to deform, which (on one bike) caused the timing to jump a tooth, causing a running "issue".

I'm posting this as an FYI, to see if anyone else experienced this.
