Top speed

You really need to calibrate it with GPS first (there are other methods, but GPS is best), so you have a ACTUAL speed and your INDICATED speed. For instance, indicated 60 on my guages, actual 56 on the GPS. You then put that into the Speedohealer calculator, and it would yield (in this case) a -6.7% calibration value. You program that into the Speedohealer.
In operation, the speedohealer reads the pulses coming from the electronic speed sensor and decreases or increases the pulse interval by the calibration value and sends that pulse to the speedometer.

I have one. It connects in series to the speed sensor and also to power.

Actually, that is the best way because it is sustainable. The GPS is harder to hold a consistent speed for the reading(s). I said GPS was the best only because of the lack of availability of a dyno to everyone, but the dyno is optimal.

Ok, so to calibrate ideally you would do 2-3 runs with a gps to calculate error then run sustained speed dyno runs to maintain and program? How much does a speedo healer cost? The cheap garmins which are pretty accurate and follow you pretty closely are only 100 bucks nowadays, although I'd imagine some people don't want an extra gadget to maintain along with the bike.
Joy you have any pics posted anywhere of your 954?

They're around $100, can find them on sale for less. Nice in that is makes your stock speedometer accurate (though it will change the odometer, making it inaccurate) and isn't another gadget to worry about.
I only have some lousy phone pics and a few track pics of the 954. My good ones got zapped in a crash. I'll see what I can find.

yep, a gps probably isn't 100% accurate but I believe it's the most accurate and versatile way to measure speed we have. you could probably use laser to make an even more accurate system but that'd only work in a straight line. and since gps units are linked to satellites the "triangulate" the receiver than i'm sure going any other way than dead straight would produce an even larger error. my bike did 144mph bouncing off the limiter, a few other guys went and wow, do not buy those jardine megaphones for the new gsxr's.
would've uploaded a video but the files wouldn't play on the camera or the comp when done for some reason?

Indicated or actual?
