12000 RPM Universal Motorcycle Speedo/Tach

Just a couple notes for anyone installing one of these.

If your bike doesn't have a fuel gauge sender, the fuel level display will flash. Installing a 10 ohm to 90 ohm resistor between the sensor wire (usually blue/white) and ground will stop the flashing. 1/4 watt resistor is fine. 10 ohm will give you a full tank reading and 90 ohm will show empty.

Wheel magnet polarity makes a difference. Mine came with 2 rare earth magnets 4mmx10mm which look the same on both sides. The sensor will only pick up either North or South, not sure which but if you attach them to your wheel the wrong direction you'll get nothing. If you put one on the right direction and the other the wrong direction, the speed reading will jump around.

There are a couple old videos on Youtube about installing this meter but the firmware has been updated since they were produced. Used to be the maximum setting for wheel diameter was 999mm but the newer ones can be set up to 2999mm. This lets you use only one magnet if you want instead of a minimum of 3 on a 21" wheel.

All the other connections are easy enough to figure out.

BTW, pushing the button when the unit is already on will toggle the display between odometer and tripmeter.
