Radiator Cap with Temp Gauge
 

I am going to try this on my CR 250 at least until I install a new trailtech voyager.

I needed to add a couple of drops of assembly lube so the cap would turn smoothly on install otherwise no issues.

The gauge is in Celsius, 93C is 200F and 107C is 225F. I will post updates.

Yeah seen one of those, but thought maybe I don't want to know. Ideal temp is about 50*C for a modern 2 stroke.

Tiny radiators covered in mud, slow speeds and lots of drag will likely make for much more heat. But compromise - compromise.

I have a trailtech voyager on my gasser which has a temperature gauge. I have it set up with the red trailech warning light to start blinking when the gasser goes over 200 degrees. I think it is always good to know before your engine starts to have a meltdown. :eek::eek::eek:

I have used these and work fine while coolant is making contact with the prob. If your not running a recovery bottle you will get false readings when the bike cools off a little after it?s been hot.

I have the exact same rad cap on my EC300, it was on the bike when I bought it a few years ago.

I wasn't too sure about it when I first saw it, but I have to say it works great and is pretty accurate. :)

Mine seems to work ok too.
