Broken instruments/gauge needles
« on: March 05, 2018, 08:08:50 PM »
One of the things that I noticed right away on Honda's Nighthawk - seems like specifically from the mid-80s, was that you can pretty much count on one or more gauge needles broken off.

I am just absolutely dying to understand why that would be.  Surely someone here knows.  I have instrument clusters from the early 70's that have perfectly intact gauges, have seen dozens of 40+ year old instrument clusters with perfectly intact needles - discolored from the sun sure, but not broken off.

First, why would a needle break anyway - it's not under any real strain unless you count bouncing off the stop pin.  Yet, of the half-dozen or so instrument clusters I've seen for the Nighthawk - none of them were totally intact.  One of them had at least a needle bent down on the thin edge of breaking off.  One had ALL 4 of the gauge needles broken - even the fuel gauge that barely moves.

Did the Japanese use particularly crummy plastic back then or something?

I'm not sure about the type of plastic used on the needles.
But mark  my word. The plastics used by early yamaha stuff was made of intsacrack .
In fact , I was staring at the fairing on my fj1200 one day and it started to crack.

"I swear if you look at me like that one more time I'll do it - I'll crack!"

"Alright you pushed me too far - <tink!>"

Ha ha.  I was repairing some cracks on the FJ. After about 120 km up the road. All the repairs held perfect
but it just transferred the vibration and front indicators just hanging by gravity. The tab on both sides broke.
