So, after a complete engine teardown and rebuild my Ultra is in (it appears) "limp mode". It won't go over ~10MPH, low RPMS.

After reading through the forum - I have tested the water temp sensor, and am getting NO resistance reading at all. So I am looking to get a replacement sensor. I have tried getting one from several sources, and it appears that Kawasaki has a national backorder on this part (21176-3731). So, I was wondering if by chance there is a cross-over part number, or a part substitute that can be used?

Any of the ones I see for sale on the "online auction" site appear well used, and are as-is.

Next on the list to complete is a pump rebuild Any advice on this as well?

Thanks for any input and / or help.
