Believe it or not, Koso NorthAmerican Technical support is on vacation for 2 weeks. Apparently, there is one guy in the Americas that can help. I am talking with others there and got some interesting ideas.

First, the main comment was that this is a Harley Speedometer and is not meant to be used on a non-Harley set up. When I mentioned that I have references of this speedo working on this bike, the conversation changed a bit.

I have a couple of things to try related to the interference issue.

Bonfire Boy,

One thing that would help from you is a little more information about the speed sensor you used. The one I purchased was called a universal Koso Speed Sensor and was about 1.5 inches long with Grey tip and Grey strain relief.

I have been trying a few different magnets and all of them appear to be signaling correctly because I can see the pulse come through on the wires as a +5V.

Can you provide any more information about the magnet setup that you have on your bike?

Any other thoughts are always appreciated.

Thanks,
Steven
