Tach issue

Hi Guys,

I'mn not sure if i'm posting this in the correct index but here it is
I took my speedo/tach cluster out to install 140 mph speedo and when i put everything back together, my tach does not work well.
It only slowly creeps up to 1000rpm and when i rev it it goes up very slow, it's very lethargic! I disconnected the cable numerous times on and off and made sure that cable is routed properly even though i just disconnected it at the tach but nothing helped
Any ideas!

Thanks
Sasha

You could try lubing the cable.
Another option would be to remove the cluster again, flip it over and put a couple drops only of lubricating oil in the tach itself.
You only want to use a very small amount because it can end up on the inside of the tach glass.

I removed the cable, sprayed wd40 to clean all the gunk out and than lubed it with cable lube and no change.
It's so weird, the only thing that I did was disconnect it from the tach.
Grrr!

So I guess I routed cable wrong. It should go over throttle cables not below, tach works fine now!

Thanks
