    I used to drill my magneto shafts on my strokers, press in a chopped off speedo drive end, rob a drive unit off a BT or Sportster timer, drill the mag cap, and run H-D mechanical tachs right off the shaft end with a Sportster cable ( I ran the tach in the dash, no speedo). Worked great, but I used up a few of those tachs over the years. And I have no issues with the word "Nacelle", I own Pre-Unit Triumphs and other Brit nacelle wearing bikes.

    It looks like the cable should have a 90 degree bend at the tach end. I guess the cable could be wrong, but who knows.

    I don't see any part or number referring to any 90 degree bend in the parts book. Any that I have seen the nacelle was drilled so I'd be curious on this finding. Here is my 68 with a hole just big enough to fit the cable through in the nacelle.

    Hey thanks Murph for the confirmation! Great looking bike! I changed both my gauges to SW with bulbs. I have a temp gauge, but do not want to drill into the head. I suppose I could use an earth ground clamp.

    Who works on tachs of speedos to roll on a new chrome or stainless ring glass retainer?

    While on the tach subject, anyone care to identify this part? I have ran into these a few times but not too common.IMG_2787 - Copy.jpg

    Someone put a drive of some sort in a pre 1965 cap.
