A quick installation report.....
Received the Koso on friday.....So far, everything is working perfectly - RPM, Speedo, Indicator Lights (FI fault light, turn signals, Neutral, high-beam)....still need to install the coolant temperature sensor that came in the kit. I made the install easier by chopping off the connector wires coming out of my stocker gauges....this made me a nice little plug n' play harness for connecting the Koso to the bike's main wiring harness. The hardware, sensors, and wire that come in the kit are all top-notch high quality stuff. One of the best parts of the kit is the Active Speed sensor & mounting bracket..... the kit supplies a small bracket that screws into one of your front brake caliper mounting bolts. Because the sensor is active it does not require a magnet to be glued to your front rotor.....the unit is smart enough to count spaces or mounting screws. I chose to use the front rotor mounting bolts.....simply tell the Koso how many mounting screws you have and it figures it out. Like the illumination on the Koso gauge, the sensor has a blue LED that lights up.... as you spin your front tire, the LED flashes....helping you to indicate that the sensor is working correctly. (at speed, the sensor just stays lit)
Couple other things to note...... I was able to wire the RPM sensing of the unit directly to the RPM wire that use to feed the OEM speedo. The Koso has another nice feature where you can program in the total mileage of your old gauge, so your total mileage will keep. The Koso does come with a fuel gauge.....so far.... it simply stays unlit until I hit reserve.... the fuel meter then starts to blink indicating low fuel. (close enough.....it works) As far as mounting the unit...... I was able to use the mounting bracket that came in the kit.....but it did take me a couple hours to figure out an exact way to mount it..... if you do it, be prepared to get creative to make it work mounting wise.
My biggest complaint about the kit..... the Installation manual is something to be desired. There is a nice manual on how to program and use the KOSO, but for install its a different story. The Install manual consists of a single page (front & back) with a Koso wiring/color code layout on the front, and on the back has a few mounting ideas for the speed sensor. Thats all you get. Be prepared to have the Honda Service Manual out with the 1 page Koso wiring diagram out to figure out what color connects to what color. There are also a couple situations where there are multiple wires running to an indicator on the OEM gauge and only one going to the Koso. So there are wires in the OEM wire harness that won't be used. Again, this is where the 919 wiring diagram is needed....... The kit does come with wire taps.... but, unless you want to hack up the factory wire harness.... I suggest that you learn how to solder.... and install the gauge the way I did --- by using the OEM speedo cat-tail and using solder for the connections.
