Ok, this happened to a car I had once. Since it could never happen to a motorcycle *this post is almost completely for entertainment*.
ON a motorcycle the speedo typically comes off of the front wheel hub. But on a car it comes from out of the transmission, where there is gear oil (manual trans.) I once had a manual transmission where the seal going to the speedo cable was leaking. It pushed gear oil all the way up the cable into the speedo. When this happened it clogged the air gap between the needle assembly and the spinning magnet and made the needle climb to max at almost any speed. I had to clean out the cable, clean out the speedo guts and replace that seal. SO anyway, you can see from this example that something goobering up the air gap between the indicator movement and the spinning magnetic round-a-majig that the cable is connected to, can cause faster than accurate speed indication. I also had a bad speedo/odometer on the `84 450 Custom that needed to be disassembled and cleaned. I learned that strong solvents will take the numbers right off of the odometer wheels. So no strong solvents in the speedo/odometer assembly. -- You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group.
