A tachometer wouldn't normally have been fitted to the T100C model.

Thanks for the help, however there is the fitting on the upper left case and a tach on the rack next to the speedo...I am in America and this may be an american bike  but ??  but still?, maybe there is a right angle some place for the speedo fitting.

As said, C's didn't have a tach as standard, but the cam had the fitting slot to drive it, so one could be fitted.

I'm not getting what you say though. The standard tach drive is "right angled" and directs the cable forwards and upwards to the clocks. I've never seen one where the cable would foul the pipes. Has someone fitted the tach drive at the wrong angle, ie, pointing the cable straight upwards, maybe?

If you look at another bike (even a pic) it should show you where yours is going wrong.

I just removed the high pipes and it has the right angle set up and I was able to reposition it for the tach cable by rotating it,.. Looks like problem solved....As this is the first Triumph I have has since 1970, there are many thing to remember. Thanks for your kind assistance.

Glad to be of help.
Maybe you now need to tighten the tach drive through-bolt though, as it's a notorious oil leak point when even slightly loose.

BTW around this time Triumph changed this through-bolt thread from RH to LH, and that's caught a few people out too...
