On another forum I frequent someone was asking about how to remedy some lazy instrumentation.  The tach needle was slow going up as the revs increased and slow coming back down the rev scale as the motor returned to lower rpm.  So the trick is as follows......cut and pasted for your reading pleasure:

do NOT oil the back of the gauge. what you can do is (this may sound odd), take the tach off the bike. get a cotton ball, and put some kerosene on it, a little bit. stuff the cotton ball onto one of the light holes about half-way so you can get it back out later, and leave tach outside 9to avoid fumes as well) in the sun face up for a day or so.

what this does is the kerosene will evaporate slightly, and re lubricate the pivots on the tach needle stem. the stem is a pivot that sits on a brass bushing and a jeweled upper pivot that is lubricated by the factory. that oil has dried up and gotten gummy. this will relubricate it.

make sure you have the gauge facing UP as you put the cotton ball in or it can drip and stain the face.


Could be of some use to folks out there.  Interesting idea.

If you can't get one, make one.

I hear that's what they used to do with the old mantle clocks - cotton ball and let it slowly breath on the bearings.

You're right on the money with your comment Mike.  The post's author indicated that he had spent 10 years in the clock fixing business.
