I saw a photo somewhere in this website of a tach mount that looked really sharp.  I would like to reproduce this mount.   The tach was mounted in a triangular piece of metal (SS?) which was bolted at two corners to the fork where it connects to the handlebars.  It was noted that this piece of steel fit nicely in between the handlebar brackets and the fork.  It seems to me that this additional spacing between the bracket and the fork would make the handlebars loose unless some of the bracket was ground off to allow for the bracket and complete tightening of the handlebar bracket.  
Comments?

I did grind off some of the bracket when I made the ignition switch mount for the handlebars.  However when I mounted the tach on another bracket I found I could just add a piece of rubber inner tube and it gave enough size increase to be able to tighten the bars ok.  See my thread in the tech section "Ryca tach buy, mount and accuracy" 05/09/12 at 19:02:35 and  General Category / Rubber Side Down! / "handlebar dash with ignition switch" on: 03/08/12 at 08:38:11
