Tachometer not working

I just purchased a 1986 750a with 31000 kms on the clock. Really nice machine with heaps of expensive stuff. Really good value and super comfortable .

I have just read he newbie stuff,...I have changed all the fluids, but now have two more jobs to do.

One minor issue with my bike is the tachometer is not working. It runs real nice, revs out through all the gears, (it has harley fatboy pipes put on my the orginal owner, maybe a bit rich ? ) I pulled apart the headlight shell, and tacho and checked all the conectors, They look fine. Before I buy a new tachometer , is there anything else I should try ?

The tacho runs of the front coil check your wiring connects in there under the left side plastic headstock cover in front of the tank

If the connections are all ok, then you will have to replace the tach. If you can find a good used one for a decent price, I'd go for it. New ones are ridiculously expensive. Are the tach light and the temp gauge working?

I am a motorcyclist, NOT a biker.

I would have to ring around, and still pay postage. If you are willing to sell yours and post to Australia I am willing to buy it. It looks in good condition. I check the wiring to the coil and it look ok. So its the tacho that nees replacing.

Before you buy another one check out and clean all electrical connections, my rev counter/tacho was bouncing all over the place after cleaning and greasing all contacts on bike it settled down to normal, the electrics do odd things on these bikes

Any idea where the wires go near the front coil. Its pretty tight in there.

Have you removed the plastic head covers, once they are off you can remove the coil from the frame and give all the wires a clean up.
