1967/1969 Bonnie Rebuild Desert Sled Project

[Sundance]

Tachometer and Speedometer: I bought a mini tach and speedo that I have installed on my 1969 T120R. These are from Lowbrow and I thought they would work OK. However, the standard Triumph tach cable does not work with this - the standard cable has a square male fitting and these mini instruments need a round cable fitting. So I am wondering if anyone has used something like this before? Is there an adapter available to make these work on my 1969 tack drive and speedo drive? Any comments are appreciated.

The cable drive MUST have a profile, a round cable cannot work, it would just spin.

Too bad they don't align "vertically" as far as the faces...

The initial opening is round, but there is some kind of feature for the cable to impinge upon, it is just not clear from the photo, seems to be a flat of some kind.

On the chance that I cannot get my “mini” tach and speedo to work with this bike . . . are there any other options for instruments rather than the original or replica smiths items? Thank for any help.

No other options that I know of, without drive ratio issues...

Yes, there are other options, you can also get electronic mini tachs that run from the positive of #1 coil, or you could source the right cable for the job, try asking the supplier.....
