I bought heavy bar end weights from HVME to suppress the vibration that was making my throttle hand go numb. I got the stainless steel ones and I think they look pretty sharp. They DID suppress SOME of the vibration so at least my left hand is not getting numb. But I'm STILL getting vibration at the throttle and my right hand is STILL going numb... just not quite as quickly. I do not regret my purchase at all but I am a bit disappointed- not with HVME- but with bike! This should NOT be happening. I am perplexed at this. What could possibly be causing this? Thinking this out, I'm wondering if this might have to do with the ABS? I've never had ABS on a bike before but I can feel the ABS when rolling to a stop at a light or stop sign: it's this smallish vibration in the bars.

It looks like I'm going to have to get some kind of mechanical cruise control/throttle lock so I can briefly rest my throttle hand to get the feeling back. I really do NOT like these kinds of "cruise control" because I view them as inherently more dangerous than an electronic cruise control, which goes off instantly under emergency braking whilst a mechanical one would not and could potentially lead to disaster. I'm considering the Kaoko throttle lock from Touratech but I dunno.... any commentary one way or the other would help. :confused:

This is after completing a 268 mile trip, so this isn't an "around town" issue. This is an issue with the bike itself. It's not tires: the rear tire is NEW. Front tire still has lots of tread left. So... what the fuck?

Kaoko will release when you roll off the throttle and does not consume grip space like some other options. In terms of your hand going numb, consider that the pull back on the fjr bars is a lot and puts your hands/wrists at an odd angle if you have wider shoulders.

As an experiment try holding the bars with only thumb and index finger allowing your palms to sit on the bars wherever they want to be naturally.

So.... how do I know if I have "wider shoulders"?? I've always had these shoulders. They kinda came with the whole body thing. I don't think my shoulders are any wider than most other guys but how would I know??? Still perplexed.

Are you average Scandinavian size or average japanese size? 6ft plus or 5.5 or so

If you're not using premium fuel, try it. My bike went vibration free when I switched from 87 to 91.

Still.... perplexed.

Also... the Kaoko releasing when you "roll off the throttle" doesn't concern me. It's when you have to make a sudden emergency STOP THIS FUCKING BIKE NOW! kind of maneuver. Y'know, to avoid a deer, avoid a collision with a clueless car, avoid some other shit that's actively trying hard to KILL YOU FOREVER. Which is, apparently, all the fucking time....

I am 5'11.5" and I don't speak a lick of Japanese so I think I'm pretty average kinda guy. A little lefty leaning but pretty average overall.

If your natural reaction is not to close the throttle you are screwed without the kaoko anyways. I have had theottlemiesters or kaoko on the last few bikes and in an emergency stop you wouldn't know they are there unless you are one that just pulls in the clutch and clamps the brakes

Just wondering why this might be the case although I think I may know the answer to this...

Odd that you are complaining about throttle vibes but link it to the ABS. Are you saying the ABS activates whenever you use the brakes?

I would start with this...
Adjust the handle bars to a different position (make sure the bolts are torqued good)
Do a throttle body sync
Torque all the bolts, especially the motor mounts and any and all on the forks
Check your tires for cupping or scalloping. Just because there's lot of tread doesn't mean they're not the cause
How's the tire pressure and wheel balance?
Check your front wheel bearings
Check your front rotors for warpage

Leaning left in an emergency is bad unless you are in a present or former British colony :p
I changed my kick stand to the other side because I don't even want my bike leaning to the left. :LOL:

In any event, at 6ft, 190 with what I consider an average MN build, the bars on my fz1 and fjr were too swept back and too narrow leading to issues with my right hand going numb. I'm in the process of fixing the fjr once customs clears the parts, the fz1 was fixed a couple of years ago.

Hmmmm... ok, this might be something I can look at- re: adjusting the bar sweep. Not real sure where it is in the set up so I'll have to go in and see. It might be as far forward as it goes but I honestly don't know. I've only had the bike for 2 months and 3 rides....

man, that's quite a list of things to check. Cupped front might be the culprit. I'll start with that. I keep my tire pressure at the recommended pressure. Wheel balance? On the front, I'm not sure until I replace it. Rear was just replaced and balanced. Wheel bearings? I have no idea how to check that. Rotors are good. I'm going to look at where the handle bars are set and perhaps change them. Throttle body sync will have to wait till I get the necessary equipment and LEARN how to do it.... not really looking forward to doing that. Torque ALL the bolts?!! Fuck this is a lot of fucking work.

It is always an adventure figuring out how to fit a bike. Change one thing at a time and evaluate. I bought mine in late April and only have about 3k on it so far, I have been favoring my other bike because it feels better. One adjustment at a time and it will get where I want it.

When installed and adjusted correctly the Brake-Away throttle lock clicks off when you pull the front brake lever. It's also IMHO the easiest to use- thumb push on, thumb push off. It can be a bitch to get right but once you do it's as simple as it gets.
