Ok....so after my recent chain and sprocket / 520 conversion
my speedo was even MORE off!!
So what is a guy suppose to do?
There is truly only one option... order a speedo healer. I ordered mine from Cal-Sportbike
for only about $95 shipped. (Thanks Sime for the link to them)
I got it last week and finally got it installed today. It was a little confusing on the install. As to understand them...but once I did, it was beyond easy!
It is a simple idea... it goes inline between the speedo sensor (off the countershaft sprocket) and the ECU. What it does is translates that signal in to a corrected signal out to the ECU and then to your speedo. It is really a simple idea once you think about it.
Now I have to go out to the highway and see how fast I'm really going!
Here's a few pics of the install. There wasn't really much to show.
Originally the black harnesses were pluged directly together... now the white harnesses are "in-line" with the SH..
The other end of those wires and the SH itself. Really small...
Wiring ran from speedo hook up that is under the tank to the unit & There it is tucked away under the front seat...
