Speedometer sticking '86 FXSTC
I noticed the speedometer needle goes a little haywire (at times) on the motorcycle, so I was going to lube the cable. But it appears the wheel has to come off in order to detach the bottom of the cable.Is that true? Thanks for any help you can provide.

No, disconnect from the speedometer cable from the gauge and the cable and sheath should unscrew from the speedo drive unit on the axle where it inserts to the drive unit. Lefty loosey. Use graphite powder/lube for the cable.
Before lubing the inner cable, clean it first with a rag and maybe flush the inside of the cable sheath with some wd-40 with a final rinse using some carb cleaner. Blow the inside of the sheath dry with compressed air, and powder up the cable as you put it back in the sheath. You can't use too much graphite powder.
Some say mineral oil, others say lithium or moly grease (light application), I just remember Dad using graphite powder, graphite powder is what I use with no issue. YD

One reason your speedo may be erratic is the inner could be frayed. Take great care when removing the inner from the outer, as if it is frayed, there could be some sharp wires waiting to catch your delicate fingers! The inner might alternatively be dry and rusted up. In any event don't be surprised if a new cable is a simpler and more reliable way ahead!

I have taken a few of them apart and put new grease in them.
There is a tiny screw involved in getting them completely apart, as I recall.

I'm still riding the 1985 FXRS that I bought new, in '85. I am one of those guys that likes to fix things, restore and keep using stuff, rather than toss. That said...when it comes to my bike..especially when it's something as inexpensive and easy to replace as a speedo cable..I'd figure the 34 yr service life of that cable is good enough. Buy a new one ( while you still can..) and enjoy another 34 yrs.
