Three week wait for the unit to be shipped from Japan. While waiting my brothers 97 VN1500 Classic developed a seriously fuel leak. Carb stripped and inspected to find some debris in the float bowl and a failed float needle valve. Carb had an hour in my ultrasonic cleaner, reassembled with new float assembly. Attached the TPS harness adapter and low and behold, readings were wrong so attempted to adjust. Lowest readings achieved were 3.6v at idle and 0.6v at open throttle. so another faulty TPS? Brother given the bad news.
New TPS arrives for my bike and installed. Reading is 3.3 on idle and 0.8 on open throttle? No useful adjustment...Why the reverse readings on the 2 bikes and then new TPS?
Any help appreciated.

I'm confused...You said this is a carbed model..NO ECM.

what does the TPS do on that bike.

From information gleaned from various websites, It sends signals to the ignition. Then the ignition unit advances or retards the ignition timing as and when its required.
