I'm only coming up on 3,000 miles and have noticed my throttle feeling sticky on my 2014 Gen III. Sometimes it has seemed like it was actually binding, or stiff. When the bike is off and I spring it down, it seems a little sluggish to return.

Is this a simple matter of lubing something somewhere in there? I know it is throttle by wire so I shouldn't have to worry about sticky cables. Any other Gen III owners have this issue?

 
Maybe need to clean & re-lubricate the throttle tube & right handlebar?

On my previous FJR after a period of time the grease was like gum and caused it to not move freely.

No problems on my '14 so far.

 
Did you not just put risers on ? perhaps when you had the bars off and laying that you got the line disoriented causing a binding on the cable.... can you move it around a bit and adjust it so there is no kinking going on....

 
The kinking suggestion is good, I will check that, and I did not know there was a cable running from the grip to under the tank.

Does anyone actually lubricate the grip itself? I thought it was just a loose and dry fit. I will look into my service manual for the cable routing and see if there are any maintenance recommendations.

In your Owner's Manual it says to lubricate the cables and grip housing at oil-change intervals.

 
Somewhere along the cable there is an adjustment like a turnbuckle that adjusts the "length" of the cable. Too tight and it binds. Too loose and you have a lot of slop. It'll be in a little rubber lump in the acceleration-side cable.

(This is all assumption, I know that adjustment is there on earlier bikes, I would assume it needs to be retained with the Gen-III system since you still have a cable that has to fit.)

 
If he just installed risers my bet is that this has something to do with that.

Risers generally require cables to be stretched or relocated, ties to be cut and re located. All or any one of these can cause a finding or sticky throttle.

I'd look for a tight cable first, take the cables out of the loom under the bars and see if the problem resolves.

 
Can the grip heater wiring impede the grip's rotation?
Yes, the factory heated grips wire has to be in just the right spot. Or at least it had to be on the Gen II's.
Echoing Niehart. At the last PNW Tech Day, we had a terrible time getting the throttle side heated grip wiring routed properly on BReamers AE. First one I've ever had apart, not looking forward to the next!

Few things are as satisfying in life as solving a problem of the mechanical sort. I've never known for sure why this is true, I only know it is. Perhaps it is because we live such chaotic and abstract lives. So much beyond our immediate control. Technology that is increasingly disempowering as it withers our ability to do anything with it. Yet since I was a child I gained enormous satisfaction from tightening a bolt down firm after fixing something on my bike or lawn mower. Hear a squeak? Find squeak. Oil squeak. Smile.

I've solved my throttle stick problem and appreciate the hive mind help of all you ladies and gentlemen (there must be a handful of ladies on this forum!). Tonight I went into the garage and for the first time took apart my throttle grip. The first time around I lubed the shaft which I had found dry, though I don't believe that was much of a problem. Then I lubed the cable barrels a bit more. Then I dripped Tri Flow down the cable housings several times. Put it all back together and no luck. Still tight, and sticky. Scratch head. Smile. Poor ******* bike does not know who his master is yet! Our family motto is "when you gotta do it, you just stick to it!" It's been useful to brainwash my sons in some sense of persistence, and has its uses for me as well. Always liked the Shackleton motto of "through endurance we prevail", though it seems a little grim.

I noticed on my Gen III that there is a rubbery hose inside the housing contained by the two halves of the casing. I'm not sure what is in this pliable hose, but when you move your throttle this hose is given room in that housing to scrunch up a bit. I went ahead and lightly lubed the hose and housing so it could slide more easily. Still no happy.

Scratch my balls, itch my head, give the bike a good stare, and smile.

I had done the easy things and now needed to move the tank and check cable routing. I had installed the MV risers some months ago (love them!!!) and not had a problem, so had no particular reason to think that was the cause. But I was just at the PNW tech day (what a joy) and did TB sync. I found when I propped the tank up tonight and looked at my cables that they were over on the far right as they were from the factory. Though not kinked at any bad angle, it was just enough of an extra bend to tighten up the cables and make turning to the left a little resistant.

So I popped the two cables under the T bar and over toward the middle of the tank. This freed up a good amount of slack in the cables and WHOOPPEE. Happy me. Joy Joy.

Now that throttle snaps back like it should and the bars turn freely and easily to full lock both ways with no binding. While down in there I sprayed some ACF 50 on the throttle springs and assembly for good measure.

Problem solved. Learned how that whole assembly goes together (a pain to reassemble the first time, but by my 15th time it was easy!).

Thanks again and keep the rubber side down.

Yes, those cables go under the Tee bar, not over it, and there is a little clip / retainer that fits under the right side bolt, that holds the cables over to the far right side.

Over the T-bar. To dot the 'i's and cross the 't's (see what I did there?

I had binding after riser install, particularly at near full lock. All was good, except the cable hadn't been properly jogged around the mount on the right front side of the frame. Disconnect wasn't necessary, I just needed to kind of mash them around to clear it. Plenty of slack after that.

If he just installed risers my bet is that this has something to do with that. Risers generally require cables to be stretched or relocated, ties to be cut and re located.
