I made up my water tubes after junking the execrable TwinMax, but think I'll be pretty happy with the Harmonizer.
I previously had a MotionPro tool with the blue ink and all the associated PITA issues. Then upgraded to a Morgan Carbtune, and have been a happy camper ever since.
So not sure if there is sufficient justification to move from the Carbtune to the Harmonizer. I my bike already has a tacho, and the Carbtune does not use any form of liquid so nothing to get sucked up into the engine.
