1 Interesting Thermostat Observation Wed May 15, 2013 4:11 pm

Today while inspecting some used radiators, I noted that both of them had a rattle noise at the at the thermostat, while shaking the radiator.
Inspection of both (1 K100 & 1 K75) revealed that the slotted square cut O-ring that seals the thermostat into the radiator area seat (not the cover O-ring) was missing entirely on the K100 and all dislodged & wrinkled up, partially trapped under the K75 stat.
I'm wondering if this is a common failure on K bike thermostats? I'm trying to figure out if these fall off in normal use or if consequently both of my radiators had been mis-handled at some time during thermostat installation?
Please report what you have found on yours????
