I've done a search, but all I can find is the temp sticker. I'm looking for the type of thermometer that is built-in to the radiator cap. I saw an ad for it somewhere, maybe here, maybe in a magazine. Just can't seem to find it now. I'll be adding a small 12v battery and cooling fan to my 450r, and this temp indicator would be ideal for the before-and-after test. Thanks.
