So I was riding my shadow the other day and I noticed that when I passed by one of those side-of-the-road speed reader things I noted that the speedometer was reading 5 mph lower than the speed reading device. I am already going to be taking it apart to attempt to repair my odometer and I wanted to replace the internal light cause it's really dim. While I am in there is there an adjustment to fix this?
I am also going to be replacing the bearing and lining the axles on both wheels. Should I consider replacing the speedometer cable and gear while I am in there?
Can anyone point me at any videos or tutorials involving speedometer repair?
The speedometer is functioning normally all Honda bikes seem to be around 5 to 10% optimistic.
The occurs with cable operated or electronic speedometers.
AFAIK there is no fix in the meter itself and the odometer is usually closer to accurate.
I have heard rumors that Honda does this for legal reasons, as it seems to affect most bikes that seems plausible.
At this point with my bike I find myself not worrying about the inaccuracy too much. If the speedometer says I'm 10 mph over it's probably 5 mph over, that won't buy a ticket around here.
Some Shadow speedometers have replaceable bulbs, newer ones I gather are LEDs and not replaceable.
...auto and motorcycle speedos are factory calibrated to read 2 to 4 mph faster than you are going. Think of the lawsuits if they didn't do that...

The GPS phone apps are also pretty good for checking the actual speed.
Just don't be gawking at it at the wrong time.
If you rig a mount to the handlebars it can make a good pretty accurate speedometer replacement.
You can also get apps that monitor other performance such as acceleration etc., if you are so inclined.
I have an older spare phone that I bring along so that all is not lost if my "high tech instrumentation" decides to go flying off the bars, I still have my work phone in my pocket.
