My 650R reads roughly 10% fast. No problem, as the mental math is easy (60 = 54, 70 = 63, 80 = 72)

I read that the US requires speedometers be accurate within -0% to +10% and odometers within +/- 1%. (It's okay to think you're going faster than actual, but not slower). Unfortunately, I don't remember where I saw it.

Was that for me or the OP? If me, got a link to a good tutorial because my research doesn't indicate a way to make it more accurate.

You have to expose the guts of the speedo and put it back together for testing or wind will affect it.
Don't have a link but have done it. You have to VERY carefully move the little plates on a shaft to give it more or less magnetism. Trial and error. Last one I did took about 6 hours and and had easy access to the speedo.

You mean at the hub or at the gauge? I'm assuming at the gauge end.
