I bought a 72 CB750 in May and it came without a tach or tach cable. I have finally purchased a tach cable (bought the tach a couple months prior) and I have no idea if I'm just supposed to jam the cable into the hole and onto the "tach drive shaft", or if there is a part that actually holds the cable onto/into the case.
It's a pretty idiotic question, but there you have it.
You know, I'm not actually certain the tach drive even works, it's "unsealed" (meaning I can see the drive shaft/pin), and the cable will pretty much just slide right in if I push it - it doesn't seem very secure...
TIA!
