I healed my speedo! Its a miracle!

People asked me, why on Earth would I spend close to $100 ($70 to be exact for a bargain-hunter like me) to get a device that would only calibrate my speedometer and not get a good "power plant" / "power stimulator" / 'electric-eel oil' device that allegedly 'maximizes' my bike's performance?

2 reasons:

1. I would rather save the $200+ these same guys spent for a real 'Power' device, like the Power Commander IIIUSB that will put a perpetual smile on my face everytime I ride the bike. Which I did back in August 2007.
Note : From what I heard, these same guys who got such a "power plant" device back then are now dumping it on the market faster than you can say 'Slick 50'.

2. I want a properly calibrated speedometer so that when I say my GSR redlines at 270km/h, it damn well is really topping out at 270km/h and not arguments from some schmuck claiming speedo error, SAE tolerance and all that crap.

Capiche?

That said, the Speedohealer is a pretty interesting device.
Installing it is a snap. Give or take, 20 minutes (most of it spent on opening up the tank).
But calibrating is a real bitch.
I need to benchmark it against something accurate.
Either I get a bike speedo (those Sigma BC computers that calculate speed based on revolutions of the front wheel and, by default, are damn accurate), log the time I need to travel at a displayed speed of 100 km/h for a distance of, say, 5 km, and do the math or get a GPS receiver and let the satellites do the work for me.
a: More money spent on a single-use device
b: I need to get a pillion and do the timing right
c: I just need a pillion with a GPS receiver

Being the cheap bastage that I am, I go for option C. A friend happened to made an investment for an Asus PDA with built-in GPS and Mapking pre-installed. Happened so he also invested in a SpeedoHealer.
So we simply spent an afternoon doing a few runs along a nearby expressway to get the speed done right.
So now, I can claim a true speed, or at least of a much better degree of accuracy than SAE's maximum tolerance of 10% error.
