Can,t be cataracts I have those in my good eye and the mirrors are still rock steady, now if I could only see what was in them.
S10 Owners, Feeling the Vibes?
- Thread starter Venture
- Start date
A simpel way to compare, at least to get a hint what is going on, could be to put a friend/partner up
back with a video camera or smartphone to shoot a short video
of the mirrors. Maybe in different rpm range.
My vibrations are directly reflected in the mirrors picture.

Bingo! If the mirrors are blurry on the bikes of those who complain of vibs, it's not a sensitivity issue. The mirrors on my S10 are clear as the day is long...no double images.snakebitten said:
My mirror are a little blurry... I have a J&M CB mount on the left one so I expected that to be more blurry but the right one is about 1/2 as blurry.. but still blurry... how many times can you use the word blurry in a sentence.
I may set my gas o2 settings and air screw back to the factory setting to see if that makes any difference as the mirrors were clear when I first got the bike.

I get the mirror blur too.Tremor38 said:
Just thinking out loud here, I wonder if my bike's vibration is not mechanical but perhaps related to fuel injection. About a month ago, I went on a day long ride up in the mountains. When I first started the bike that morning the weather was cold and foggy. The S10 was running very smooth and I recall thinking "finally this thing is broken in". I stopped for lunch and restarted the bike afterwards. By then the temperature had risen significantly and the bike went back to its old buzzy ways. I can't think of anything mechanical that could have changed in those 30 minutes. Did the computer somehow reset itself when it was restarted? I don't know. Also, I seem to recall someone else swear that their bike was smoother on cold mornings. I can't see how whether its 40 or 90 degrees out drastically affecting anything mechanical.
I would never consider mirror clearness as the definitive vibration litmus test. I have had bikes with relatively clear mirrors and annoying vibes and vice versa. And the mounting of the mirrors is just as big an influence as the vibes the engine is making. Most bikes, including my S10, fuzzy up the mirrors to some extent in some RPM ranges and load situations.

Sounds about like mine. Keep us posted of your results after going back to factory settings.Mellow said:

I get mirror blurriness over 75 mph or so. And it's fairly viby at 80+, BUT I am running Heidenau K60s, so I know some of it, possibly a lot of it is simply tire related. At 7k or so now, most of that on the K60s, it's something I've just lived with. I think it's more vibration prone than the FJR, but a throttle rocker and VistaCruise help and I'll probably look at some different grips too. Never have liked the small diameter Yamaha grips.
Can't help but wonder about a throttle body sync and if anyone has tried those "bar snake" devices on the S10?

I don't think you could use a bar snake on the S10. On many bikes the bar ends are secured by a rubber donut that expands inside the handle bars as the bolt is tightened. On the S10, the nut is welded to the bars. I don't know how you would get past the nut unless you cut it out. Then you would have to figure out how to re-install the bar ends.EricV said:
I removed the crash bars and skid plate and took it for a ride. The vibes are not as bad in the lower rpm range but are still there at 4k and up to around 5k. The mirrors are much clearer at the lower rpms, but no change in the upper range.
I called Yamaha customer service and they have not heard of the problem yada, yada, yada...
The person I spoke with said it was supposed to vibrate. So much for that.
I have decided to try the Rox riser with dampening. If that gets rid of the buzz at the higher rpms, I'll keep the bike.
If I didn't like the bike so much, it would be history. ::025::
I am going to play with the TBS some more in the morning. I don't think this will work, but what the hell, nothing ventured, nothing gained..(I have been playing with the tbs for the last month).
@ Scottie Boy, Have you heard anything from Yamaha?

I have not been given an answer from Yamaha yet. The dealership said that they are waiting on the RTA (Regional Technical Advisor) to tell them what the next step will be. When I spoke to Yamaha yesterday, just to pester them, I called bullshit on the "we've never heard of this before" line. If we hound them enough maybe we will get some sort of resolution to this problem. Japako PLEASE call back again to the same number, option #4, and extension #7867. This will put you in touch to the same person I spoke to, whom I believe is a supervisor. We need to stick together on this.japako said:
I've said it before but I'm really bummed about this situation. Every year I save up all of my vacation and take it all in the Autumn to go camping and riding. Tomorrow morning, I'm heading out on a multi-day trip but the Tenere will be staying at home. My trusty old ST1100 is loaded up and ready to go riding.

I guess I was well conditioned that vibration is normal. I came from riding a BMW K100 to the SUper Ten and tbh this is nothing. I wiould be willing to rent the ol brick out for a real bone shaker to anyone wanting to compare the two.
In all seriousness though keep us up to date on what Yamaha says .

The stock mirrors on the S10 all mount the same way, poindexter. ::025:: I'd say that's a much better indicator than speculating about various sensitivities of people when it comes to vibration. Secondly, we are talking about those riders who have mirrors (again, S10 OEM) that vibrate steady-state...not just during RPM changes and certain load situations. Thirdly the guys that have the steady state mirror vibe also report a constant 'buzzy' nature to the vibration. All of those things are a far cry from optimal or even normal for this machine. Couple this with the fact that 3 or 4 S10s in SA have been replaced by Yamaha due to vibs, and you can't just dismiss this like nothing is wrong.markjenn said:

Thats called Choke
If you monitor your bike closely you will discover he gets a richer mapping in cold weather, tickover the most noticable part, and in other respect any bike runs better on cool air, just because the fysics of it, the cooler the denser, thus the more oxigen gets in, and the better the mixture burns.
Thats why Turbo's get intercoolers, the warm air coming out of a turbo would even make the engine loose power, so they cool it
I haven't had that many opportunities to drive faster than 120kmh lately, but yesterday I got a chance. I can confirm my earlier observations that when cruising at or below 120kmh there is no mirror blurrieness and the bike feels smooth. Above 120kmh / 4000rpm the vibes kick in and are visible in the mirrors. High frequency buzzy vibes as others are reporting. I don't suffer from it and to be honest don't see it as untoward or unusual. Now if others are saying that they are getting zero vibes above 120kmh/4000rpm then that will change my thinking significantly!
Just did a little maths. At 4000rpm the big twin "thumper" is firing at 66.67Hz. Guess we can assume that some kind of mechanical resonance starts at around this frequency or simply becomes noticeable as the power ramps up.

Today I altered the fueling in the close loop area, switching between stock fueling and +7 %. This does make a difference for the better!
I have the PVC and the O2 Optimizer to override the ecu in the close loop. Is the CO adjustment by the diagnostic mode making a similar effect?
If so, try it out!
I was so totally happy with the bike today, even the cruising in higher speed (135 - 150 km/h, the vibration zone) was wonderfully smooth and comfortable. The
mirrors will still show a somewhat "shaky" picture but the vibrations have transformed into a more gentle puls that only gives a really nice feeling.
My thinking is the bike needs a pipe (probably even greater results with cat-free headers and an even more freeflowing air filter) and some fuel added to get to the source of the vibes and cure the problem.
This as a part of more beneficial changes mentioned earlier. ::012::

This is a tricky one. Now that this thread has captured my attention I have started to pay a bit more attention to the vibes. Interestingly this evening driving 150km, +6 Celsius, low humidity the vibes were barely noticeable. I don't have PCV, I have 100% stock, however possible commonality is cooler, dryer conditions meaning more fueling. This wouldn't surprise me if this is close to the matter at heart here. We know that Yamaha have been forced to mess with the fueling in the the 4k+ region for noise emission purposes as evidenced by the power/torque droop that is felt.

I had this problem with my FJR and the Super Tenere. The solution for me was a McCruise control. It allowed me to rest my right hand off the throttle.
I have not had this problem on my BMW K1300GT or Honda GL1800!
Hope you find a solution.

I have a kaoka cruise and that does help some, but not enough.Texas Country Rider said:
Thanks for offering some ideas, but I have decided to sell the bike. I am selling parts in the for sale section.
Yeah, I suppose there's a point where one just has to say enough's enough if it's truly uncomfortable. Sorry to hear the bike didn't work out for you. Let us know what you replace it with and how that worked out.japako said:
Ride on!
