Anyway to recalibrate the speedometer?

[mike_mike]

Is it possible to recalibrate the speedometer?

It is accurate at low speeds, but not so much at higher speeds.
I would like to flip it and make it accurate at high speeds and let it do its thing at low speeds.

When you figure it out, let us know.   

I don't really care what it says, close enough is close enough.  If you just have to do it, increase the preload on the needle hairspring.

The gears inside of it.

It's a percentage error, so with speed it becomes greater.

A seedometer shop should be able to handle this. Take it there, talk to them. They are like watchmakers. Few and far between, but all exceptionally skilled.

There are no gears inside the stock GS speedo.

You're right! That was more than I ever wanted to know

If you know what the genuine speeds are then you could make a new paper speedo scale and stick it over the original.

In an 80km/h zone I find riding at 85 indicated keeps me with traffic.

Wow.

A speedo shop could still do it though. I mean they DO make them from scratch for hot rods and stuff.  They fixed my 79 Buick's speedo, which was considered a Junkyard only part. Lot'sa little gears and pieces and needles and whatnot.
