Thanks for the clarification. Let's hope that the MoCo gets their supplier's Quality Control and specs improved. There's really no excuse for such a shoddy mismatched part being offerred with an HD part #. Inexcusable IMO but just another example of HD taking short cuts at their customer's expense. I'm afraid there's a tough day of reckoning in the future.
Well...... in a funny way it's not mismatched. They just matched up against the wrong instruments.
When someone was instructed "go match the silver instruments for an oil temp gauge" that person did exactly as he was told. He (or she) grabbed a speedo or tach and built a dead-on match. Needles, needle stops, etc. Ooops.
Trouble is the smaller diameter instruments aren't like the larger diameter speedo and tach. Ooops.
It isn't a gross difference. But it is a difference. It was even weirder when they were first released though.
At initial release the group here had (and showed pictures of) at least three different variations of the silver oil temp gauge. And this is the then newly released HD product. We're not discussing that really way off McEwen (sic?) aftermarket gauge that wasn't even close.
All in the same part number (no revisions) there were at least three different looks to the silver oil temp gauge. Perhaps three different subs building them? Who knows. But for awhile they were all on the shelves at the same time. So while mother Harley never got the gauge exactly right they did give themselves options from which to choose the one that was least wrong
