is this to replace the filler or drain plug? (more questions to follow upon answer)
you are talking about using this for a Hayabusa and not a Harley?
current analysis = Daft and then some...
It reads in ºC so 140ºC=284 FI'd buy one right now if you have it. I see the oil temp numbers are not high enough though. Should go to 200 + F?
it wont work on a Hayabusa. Any kind of a probe on the end of that gauge would come in direct contact with the clutch basket. There's also no direct shot from the inlet down to the oil sump. That means a probe will never touch the oil. The only reading you would get from this temp gauge without a probe would be the ambient temp within the clutch housing which tells you nothing.
