    Yeah, for sure, easier, and it gets away from the problem of what to do with the empty speedo-drive hole. I think someone sells a blank to put in there for something like $15-20 bucks.... yikes!

    tempted....:thumb

    today i bolted the koso units onto my /7, i didnt like the look of the digital readout and would rather have white dials and bare metal to match the bike.

    tomorrow ill no doubt use your wiring diagram on page 1 to figure stuff out :huh

    sorry about crappy pics, blame HTC

    me too, i'm taking a gamble not using the acewell units, but in theory the both front wheel sensor and tranny cable provide a pulse per rev which can be calibrated from the digital speedo, lets see, if not ill be selling the acewell cable:deal

    One downside to the Acewell IS the digital readout. Angle needs to be just right to see in darkness. Once you have the angle correct all is well. Reliability might be the other downside. Mine works perfectly (so far) after a couple thousand miles and some soggy conditions. I recently did some searches and the Acewell model I purchased last winter doesn't show up anywhere.(?)
    Does the Koso unit have nuetral light / signal indicators / oil light / etc?

    i have the bare 55mm GP versions, they have a trip meter and temp sensor you can mount wherever you want.

    there are other models with all the turn signal, high beam, etc indicator lights

    What I want is this with a rev counter.

    I just can't get over it that Acewell is the only company making a affordable tacho with a rev counter as well.:huh

    Fixed it for you. And yes, me too. I like the analog movement of a tach needle.

    Thanx :)

    Sometimes the English here gets a bit to technical for me. Weird enough they don't teach you motorcycle parts in English classes at high school here.

    Do you guys have model numbers or links for the Koso and those VDO gauges? I don't seem to see any of them on their websites.

    I really like those VDO gauges.

    ok, so Ive mounted the acewell tranny sensor. only one problem, how the hell am i going to dial it in:eek1

    the sensor from the tranny has 2 wires while the koso front wheel sensor has 3, i popped up the back wheel and put it into 2nd and added some gas just above idle (should be around 15 kph right). searched the internet for and explaination of the wiring colours of both units, nothing. any electric guys out there? is there a way i can use my multimeter to figure this out?

    then i just have to add the cir measurements and get it to translate somehow to wheel diameter. i'm assuming that the sensor reads rotations from the driveshaft and that maybe one full rotation of the drive is more or less one wheel rotation. i really don't know anything about the gearing etc, as you can probably tell :1drink

    I thought the guage had a function that allowed you to calibrate the speedometer..... Do you have an owners manual for the gauge?

    Sporking? That's whet you kids are calling it now?

    Best guess:

    You could try hooking a multi meter to it, set it to ohms so you got some current going to the thing. I'm guessing that it works like a magnet pick up, in that when there is continuity (or no continuity, depending on how it's made) that would be one revolution converted to tire size or distance traveled. (pull the plugs, put it in gear, roll it to take the slack out of the gear train and find continuity or no continuity depending on how it's made, mark the tire or hang some thing off the bike to get a distance measure at that point, roll it again till you get a continuity/no continuity, and measure the distance traveled. Plug that into your formula.

    Or find a GPS and head out for the day.

    Are you getting no indication at the speedo? Did the speedo come with a wiring diagram you can post?
