Installation

The MLX-3000 is a direct-fit replacement and uses the original housing, gaskets and screws.

1. On tank-mount models, begin by removing the dash. All models: remove the two screws on the back of the gauge

housing, then unplug the factory gauge, noting the position of the rubber gaskets; one on the front between the

gauge bezel and housing and (on handlebar-mount applications) one on the back between the housing and the

back plate.

2. Transfer the original gaskets to the MLX-3000; connect the supplied power, indicator and speed harnesses. Also

connect the optional MBM harness if readings for compass, boost or air pressure are desired. Route the MBM

harness under the seat.

3. Secure the new gauge using the original screws.

IMPORTANT NOTE! This gauge has an odometer preset option that is only available for the first 100

miles (160km) of operation. See “preset odometer” on page 7 for instructions.
