I finally got off my butt and lubed my throttle cables.
A year or so ago I decided to do this so I took the two screws out of the grip housing on the handlebars and checked out the possibility of getting the cables loose.
As some of you know, the cables can't be taken out that way, so,I said to hell with it.
This time I tried loosening the cable nuts down by the throttle body.
Without taking off the fuel tank and removing the tie straps, the cables didn't want to come off that way either. That's when I had a "hmm" moment.
I loosened the two screws on the handlebar housing and moved the top out of the way. That gave me a visual access to the places where the inner cable goes into the outer sheath. It was too far down in there to be able to pour oil into them but I recalled my wife has some hypodermic syringes she used when she bred cats.
Getting one of these and filling it with light weight oil I could place the end of the needle down between the cable and the sheath and very slowly inject the oil.
After injecting the oil and letting it run down thru the cables I put things back together, wiped off the dripped oil and was done.
The throttle action seems to be much smoother now so I'm a happy biker.
