mechanical tach

[argonsagas]

Has anyone tried repairing a mechanical tach?

Mine quit today....while driving, the needle just dropped back to zero and stayed there. RPMs were getting up at that time, probably about 8k.

Cable connections were firm, but I disconnected it at the housing, tried twisting it by hand and found resistance. Started the engine and watched the cable turn. Checked the engine end, reconnected it at the tach, started the engine, drove the bike. Needle stays at zero.

It appears the problem is in the tach.

Never had one apart and don't know what to expect.

Ideas are welcome.

take that tach apart

Time to search for a new one. Even if you get it apart there are no parts available to repair it.

tach problem

Hi

I have a problem with my 1980 GS1100E tach and was thinking of installing an aftermarket electronic unit if I cannot sort mine out.

Has anyone done this yet? Any ideas on this would be appreciated.

Very expensive to do!! unless you want to spend $300 new (Autometer)or maybe find something used that you can adapt

I had no idea they were that expensive. I hope that I do not have to go that route. Thanks for the info.

Well, nobody mentioned the "Little Bo Peep" principle. You know that one...." Leave them alone, and they will come home...."

Went for an hour drive and it was at zero, then began showing about 2k RPM, rose to about right RPM's while driving at a steady speed, dropped off again. After I stopped for gas, it went back to normal.

Obviously something is wrong, so I will get another one.
Thanks for your advice.



Patrick....some after market units are available for fairly cheap....I saw an ad for one today at $49.99. Actually, I was in their store, but buying trailer parts. Ad says it is good for 4, 6 or 8 cylinder engines.

Thanks for the information and link. I want to fix or replace my unit and this would be a cheap(er) short-term fix if I have to find a replacement tach.

I think there are some reasonable priced units available, but make sure they are designed for motorcycle use. Weather, you know. Probably cheaper to find a used part.

Thanks for the advice. I reckon I will try to find a used instrument cluster.

It is nice to have a tach but I can get along without one for awhile longer if I have to (if the front wheel stays on the ground, I am probably not risking any red-line encounters).

I found a little unit called Tiny Tach, its electronic and costs about US$40
its also simple to install. 3 wires, 1 power feed, 1 ground and the other wraps around #1 spark plug lead. They are used on microlites I think. I havent tried one myself but you could look into it if you want. heres the website www.tinytach.com

Thanks for the suggestion. I looked at their website and the unit looks like it would be good for a test instrument. I do not think it would hold up to usage on a bike. The tip is appreciated though.
