I think my tach is broken Help!!1

Ok, well I have finally gotten my bike to get out and stretch her legs. I have replaced the tach cable with a used one since my old one was twisted and bent.

Here is my question, what rpm should I be at doing 65-70?
My bike says im at 9,500rpm in 5th. Is this right? Cause it still has alot more pull, but I didn't go any more, cause my tach said I was redlining.

Did I install the cable correctly, is there a proper way, or is that cable faulty as well???

I am talking about my GS750L, any help would be appriciated. Since I am trying to go out for another ride today.

The engine would be running about 5000 rpm at 70 mph or so. It shouldn't be too hard to find a tach, check ebay.

I have the whole cluster off of my 79 GS1000L I just wanted to know if it indeed is broken. Looks like time to grab coffe and the tools LOL thanks

Well I switched them out, and now it reads correctly, just slow? Hmm???
Even the spedo is slow...

I pulled the cable and it spins just fine, guess I will have to get some diff ones.
