Looked in the tech section but didn't see anything for this.

If I missed it, I apologize.

Is it an easy thing, or is there stuff I have to take apart?

Thanks in advance.

That's a great method.  Since I've got rian forcasted for the next three days, it looks like a perfect time to oil the cables.

Went and set mine up.  Looks like I've got two IV bags hooked to my bike! I'm using 80W-90 oil.

I removed the IV bags and hooked the cables back up this morning.  Wow, super smooth.  Much better feel.  It's nice knowing the cables are well lubed with quality oil.  In the past I usually sprayed WD-40 into the end using the little red straw.  Of course, only some went in and the rest went everywhere else!  This is so much better.  Since mine's an '06 that was bought new last summer, I had figured the cables didn't need oiling yet.  I can see now, and feel, that they did.

And for those of us with less patience:

Cable Lube Tool

I've had one like this (mine says YAMAHA on it) for over 30 years and it is still going strong.  I like to use chain lube or Tri-Flow on my cables.

Choice here is to spray a little chain oil into the cable (very thin when it goes in, evaporates into a film on the cable when the carrier departs) or physically move out all the trash and gorp from old lube and replace it with a deep total saturation of heavy gear oil.  

(hint:  your wife already has the rubber bands and baggies for free and those cans of chain lube costs you some pocket money)

Those that have used the trick are reporting the change in feel from a saturation lube job.  Soon they will report on heavy gear oil being around visibly the exiting internal cable ends for months & months & months.   Then they will report on how the single application lasts for years (but that should logically take some years to happen).

Savage Greg had him a good trick with the little rubber band and the baggie.  Kudos to one of the old departed master fix-it trick writers -- I still miss him.

If you ever drain your brake lines totally dry and can't get your brakes to pump because of it, do the baggie trick with brake fluid instead of oil.  

You can squeeze lightly on the brake fluid filled baggie and refill your brake line totally.  You need to just crack the bottom banjo fitting a bit to let the air out while you lightly squeeze on the brake fluid filled baggie attached to the top banjo.  Once you see that the air has stopped bubbling and you have a flow of solid fluid, snug the bottom banjo back up and you got a line full of fluid that will pump from the master cylinder for you.

Saved my butt, it did when I couldn't get a pump up to save my life.

Congrats to the Haynes people, congrats to Savage Greg -- it is still a good trick wherever it came from or from or from whoever teaches it to you.  

(it was in the 1970's era Clymers Honda S90 book as well)

Key point of the trick is you can lube a cable with a significant amount of a long lasting oil with the cable still sitting in place on the bike.  

If there happens to be a down & up loop in the cable run, well it gets completely filled up with oil and the oil stays there as a reservoir to keep suppling oil to the rest of the cable by osmosis through the cable weave itself.

Long lasting, the heavy oil baggie trick ...

Yes, you can use a lighter oil if you want to.  But if you want that buttery smooth feel of a clutch cable floating in a supporting sea of 90-140 weight gear oil nothing else will substitute.

Fair warning though, our clutch cables continue to ooze the heavy gear oil for a long period of time and it winds up making little oil droplettes on the clutch to engine lever bracket that you have to mop up occasionally.  

I don't mind, shows me it's still there and still working.

Side benefit is your little rubber bellows won't dry rot near a quick when they have an internal coating of heavy gear oil -- they stay nice and fresh and flexible for a long time.

I haven't noticed the grit you mention, but I am sure I am wiping it off ongoing as I have to clean the bike periodically.   Have any of you who ride all year noticed that in the winter time all the little birds like to perch on your warm engine cases to warm their little cold feet up (must be like a emergency bird hostel to them little brown tweety birds)?  Leave you little white presents on your cases, they do.

I have to wash my bike more in the winter than I ever have to do in the summertime .....

Good deal.  I put about 8 ounces of oil in each bag.  You could do it with less oil but I wanted the weight of the oil to push the oil thru.  When I removed the bags I left the drip cups in place overnight.  I've had a few drops since on the clutch cable but not since on the throttle cable.  Oldfeller's description of "buttery smooth" is right on.  It feels like a lighter weight clutch now, maybe like a V-Star 650 clutch.
