Misting clocks
« on: July 15, 2021, 10:26:08 PM »
Just been  out on my rd350 on a dusk run. It reminded me as to how poor the lights are, how did we manage back in the 70's? My question is about my clocks though, has anyone else experienced their clock faces misting up on the inside of the glass? Having put the bike in the garage after getting back a check on them a few minutes later showed the glass had began to clear. Does anyone know why this should happen and can anything be done to prevent it?

Less traffic on the roads back then in the 70s

If the clock has been taken apart, it may not have been put back together tight enough to seal it, or the seal could of perished or the light bulb holders, just a couple of things to check.

Temperature decrease on the clock face (cooled by air rushing over it) causes condensation. Many (maybe all) are prepared with an anti-fog coating when new. That doesn't last forever, though. I try to remember to apply some when I open them for repairs (shaving cream, left-over dive mask anti-fog, whatever I have handy).

Exactly Tore!

I never found the lights a problem back then or now, although I do little night riding.

I found even the fizzy headlight  great after push bikes with little more than candles on the front. I only ever replaced one once on a Suzuki GT550 to a Lucas bright eye, it flattened the battery with night time town riding so it came off. Wasn’t noticeably better in any case. Your eyes at 60 odd only let hslf the light in compared to a youngan they say.

IMO, there is no doubt we had great vision back then, and great reactions, and great strength!  :)
Also, no doubt that a 35w tungsten bulb is not good compared to the Zenon lasers we are now used to!  :)

Thanks for your answers re the clock misting. Thinking about the lights, they are poor compared to modern lighting. I do remember though back in the 70's having to concentrate hard on some bends because the lights inadequately lit my path particularly when I had oncoming traffic. Double bends were even harder. As mentioned, there was less traffic back then and we just had to cope with what we had.

Yes, my 400c clocks also steam up in the cool of the evening.

As regards lights…I remember in 76 on my new 250c, developing the technique of setting the headlamp to dept and holding the pass light switch in to have both beams on at once. Very enthusiastic riding at night over Hartside and Kirkstone passes needed all the light you could muster up!!
