INSTALLER NOTES: On some models the supplied wiring leads may need to be trimmed to fit the bikes connectors. Use the Ring Terminal for all
chassis ground connections. If you mount your Tach high up on the handlebar, or have tall or pullback risers or wide handlebars, you may need to
splice extra wire to each colored wire lead of your Tachometer prior to completing the routing and connection, then trim to appropriate length.
GENERAL MOUNTING INFORMATION
1. Mount new Baron Tach on handlebar in your preferred position. Ideal location is between handlebar risers. If mounted off-center, you can rotate
Tach face back to vertical (or any position you desire) by first loosening Tach unit's set screw (located in handlebar clamp area of the Bullet housing or
on the underside of the Mini-Bullet housing). Unscrew the housing's bezel (counterclockwise) then rotate the Tach Face to the desired position,
re-tighten the set screw and re-install the bezel.
2. Secure handlebar clamp by first tightening the flat/front dial side of clamp and then the pointed/rear side of clamp until housing does not rotate
under mild pressure. There must be a small gap on the pointed side and no gap on the flat side when the clamp is correctly tightened.
Our install guides provide a basic outline on the proper installation of our products. Further tuning and/or
