Not sure if anyone's still interested in this thread- it's 4 months old, but I want to make some custom brackets for a tachometer- but not the mini one. I want to keep my regular sized speedo and get a regular sized tach that matches it, then make some brackets to install the speedo and tach right over the forks, like this:
My question is does anyone know of a source for tachometers of the same size as the stock bonnie speedo?
Good to read your comment - you're not alone, others have suggested some brackets that do exactly as you've pictured, suspending the gauges apart, using the fork bolts like some of the older Bonnies... agreed, it would look cool!
Couple of things to keep in mind - choices of tachs & speedos for the Bonneville besides the stockers include minis, mini-mini's, some really cool high-end stuff, and whatever you can make work... :-D .
Question - are mini-gauges out of the question for the project? They look somewhat closer
sizewise and stylistically to the gauges in the picture you posted than the stock gauges do... let me know if you'd consider going this route, I may have a couple of these brackets left...
Meanwhile, back to the fork bolt-mounted bracket concept... one puzzle that has yet to be solved... the existing fork bolts seal the forks... because of their design, I'm not sure you could hold a bracket down with the OEM fork bolts
while maintaining a seal without getting into more involved machining of the brackets... there's fine threads, spacers and O rings under there... Loxpump has suggested drilling and tapping
a small hole into the top of the existing fork bolt and running a fastener through the bracket into that hole...
Say you had the custom brackets fabricated and had solved the sealing issue/fastening method... routing of the speedo cable would need to be
worked out, as of right now the position of the headlight bracket right under the speedo looks like it might not allow the speedo cable to connect. Are you ok with rotating the speedo CCW - 30 degrees or so - to allow attachment of the speedo cable?
FYI - new "lay-flat" bracket due out soon, uses stock tach, speedo & indicators... far different from what you're searching for, but may be
worth considering, here's a pic...
