Had to do some speedometer adapter work on two sleds yesterday. The first was fairly easy. The adapter had come off and the speedometer was not registering. That was a simple fix of putting in a new key and reattaching the adaptor. Although, this time I added thread lock. Hopefully it stays. I will have to keep an eye on it.
The second is the source of the conundrum. This is a sled that we put together last year from spare parts. I noticed, while riding that it was giving me speed that was easily two to three times the actual ground speed. Checking the adaptor it was one of the 1:1.375 adapters.
That is when I checked the bag of spares. I found left and right, which I learned the hard way a few years ago. All the lefts stamped 1:3. And then there are the rights. Some of the rights are 1:3 and some are 1:1.1375. I can only assume that somewhere along the way, the adaptors and the speedometers were changed so that they both matched.
Does anyone have a way to identify which speedometers match up with the 1:1.375 adaptors other than by trial and error? My memory gets a little fuzzy at times, but I had thought that I had gone through all our speedometers once upon a time and found them all to give the same response to a known speed input. But like I say, my memory can get a little fuzzy.
