sticky Tach

Postby filupsd » Wed Oct 10, 2012 12:05 pm



I recently bought an 84 GL1200 standard. I think I have ridden it more in the last month than it has been ridden in the last several years. It runs great except it will not idle. I'm sure the jets are varnished and I will get tho those this winter.

Anyway, I have noticed in the morning when it is cool (below 50 degrees) the Tach does not work. There is usually more moisture in the mornings also. Is this an electrical issue?

Thanks David

If it starts to work a little more as you go,kinda sluggish,It is most likley dried up lube on the needle bushings.A half drop of light oil on each one cured mine.It took 10 seconds to get it to finally show the rpm.Really slow moving.

Thank you

I noticed it on the cooler mornings and it would not work on the 5 mi ride to work but worked at lunch time as it got warmer. How do I get in to lube the needle bushings on a Standard?

On mine,I disassembled the cluster and used a syringe to add a drop of penetrating oil.On the round dial type,I pried off the chrome ring to get access.

Now obviously if you do have a loose connection it can kill the tach dead.mine just wouldn't move for a few minutes and then gradually started to work.real sluggish for a few miles.
If yours goes from dead to perfect it could well be a electeical connection.
