KOSO Temp/Tacho

Rev counter KOSO GP Style II

CHT?

The Koso "should" have CHT according to the manual, however will it go high enough? CHT readings should go up to 400F.

A simple test was done by holding a lighter under the water temp sensor. The reading climbed to 150C but went no further. So the gauge is no good for use with air cooled scooters where normal running temperature is 320F-380F (160C-193C).
