Well, first of all, I'm not selling these things. My original speedo didn't have one, so I bought a speedo from e-bay that did. Also, it was my original speedo that had the hole broke where the "gizmo" attaches to the reset...that 1/4" piece hanging down from the speedo. Between the two speedos, I was able to make one good one. Since there were a couple of guys in the club that needed the reset shafts, and I had an original, I just made a few. I didn't charge anyone for them, as it was a one hand washes the other affair. I retained the original as a template in case I ever had to make more. No, I'm not going into mass production, but if you want the dimensional data, I can supply that to you.
If you got one of these, it would work provided the hole where it attaches for the cotter pin is OK. Then there is the problem of the fiber gears inside. Very often they are stripped out. If both the total mileage and trip mileage numbers are working, then you're OK in that area. If either one of them is not working, then the fiber gear is stripped for the one that is not working. This is very common, because the steel shaft for the gear runs in an aluminium housing, and the original lube grease becomes stiff and dry after many years and binds up the shaft. When that happens, the teeth on the fiber gear strips right off. /bcforum/images/%%GRAEMLIN_URL%%/cryin.gif
