you know your differences now buddy.
(speedwise)
just ride your bike since it works fine...
hell I don't look down all that much anymore on my bike
(you kids with the f4i gauges will know what i mean when i say at night, i dont like that bitch blinking red 270* at me)
get a gps for 50 bucks from ebay if you want a speedo that bad :)

I am currently making a sweet gps bracket modd for our bikes, so that might catch your attention

Spicy, I thought you changed your thermo unit. How come you still get the red overheat light? Also post pics of your gps bracket once completed. Thanks!

No I have the sensor sitting beside my bed :)
I am just gonna wait and put my jet kit in when I do it,
I stripped the sensor just a tad doing it the dumb way...

Gonna wait and throw in my APE manual CCT as well.
and my frame sliders.
and my undertail.
and my 50cal sniper rifle swivel mount.

if you do, invest in some good pliers and such...

Pliers instead of the 12mm wrench/socket your saying?

Hahah no i meant "tools" in general.
I have a nice ratchet set that bends and swivels and whatnot.
also have a torque wrench so i don't have to lean way in the bike...
20 buck investment at walmart

I swear people with OCD should never ride motorcycles. It'd murder them :p

With stock sprockets and stock rims and tires you'll ALWAYS read higher than what you're actually doing. Reading 95, you won't be doing 100. Doing 94 and reading 100, yes. Bikes follow an International Standard, UNECE 39, as in the US we can follow either an SAE standard or UNECE 39. No reason for Honda to have to follow two different standards, so they use the International one.

The general error, allowed by regulation, is up to 110 percent plus 6.25 mph. So, doing 100 mph, it can read up to 116. Doing 60, read up to 72. Luckily, Honda sticks pretty much with 5 - 8%, depending on tire wear.

I used to repair and calibrate speedometers.

And by the way, a standard GPS (like your TomTom, Garmen, etc) don't have a quick enough sampling rate to effectively use as a speedometer. You can slow down or speed up and not have the unit respond fast enough to accurately display your speed - depends on the screen refresh rate, the samping rate, and the HEPE (Horizontal Estimated Position Error). You need one that is designed to be a speedometer, and not tell you when to turn left to get to Starbucks. Of course, they cost more. If you don't mind the lag error, then it's OK and will save you a lot of bucks. Cheapest one I've seen is around $400.
