Speedometer correction options?

At an indicated 70 mph, I am only really doing 67, about a 4% difference. I assume the odometer may be off by an equal amount. Does anyone know of an after-market adjustment device or can the dealer adjust with the SERT? BTW, this is with stock tires, stock gearing, etc. on an 08 RKC.

If I look at my GPS and at my speedometer, there is always a minor difference of 2-3 mph. I live with it. IMO, it's not worth the effort, but that's just me.

I have it about that bad, perhaps a little worse. I check with the dealer and they told me it was in spec :-(

So I depend on my GPS for speed.

Mine reads 2 mph high.

It reads high so I look at it as a little safety thing.A little cushion against speeding tickets.

There is a product called speedohealer, but I don't know if it fits our bikes.

The error is a minor 5%. So, I run 10% over the posted limit. This is well under the LEO's trip point. Everybody is happy.
