Faulty Thermostat?

[AlexAdams]

I've not seen any posts on here about thermostats failing, but I think mine is lazy which is a tad surprising as my bike is very low mileage (4k). From setting off the temp gets to 94°C in a reasonable time before dropping to slightly under 80°C but then continues to go up and down between 80°C & 94°C.


Normal, or new stat needed before it leaves me cooking & stranded?

Mine does that on the motorway. I assume it's normal cycling of the thermostat, as it essentially has 2 positions, open and closed.

Sounds like it's opening.

Pre K7 by any chance? They seem to run hotter than the later twin sparks.

Yes single spark k6.

Mine does that rockets up then falls like a stone through a wet paper bag. I hate wet paper bags (quote Marvin the paranoid android).
Learn to ignore it... works for me.

Sounds normal to me
