I bought one of these to use on my KZ1000 that I'm converting to MicroSquirt. It's well a made product, and Mario went above and beyond in the customer service department patiently answering lots of questions from a guy who wasn't gonna spend much money. Already have and will continue to recommend The Dub Shop and these sensors.
This works perfectly as a CTS on an ACVW. As a bonus, it also gives you an idea of what your CHT is. While certainty not as accurate as a proper CHT gauge, it’s comforting to see the indicated temperature go down as cooling fan speed goes up.
