S10 Owners, Feeling the Vibes?

[RMac]

I´ve earlier noted exactly the same thing earlier in this thread about the vibes being less in cold weather. I think S-flow is spot on about the fueling and exhaust system being the root cause. Even in warmer weather the vibes do not upset me, but here in Sweden we do not get anything like the hot weather you guys see Stateside.

I wonder if your bike is suffering from a ever-so-slightly lean misfire when hot? It could be misfiring just ever so slightly to cause a engine imbalance which would be felt as a vibration. Since the air is less dense whit high ambient conditions, the fuel mixture leans out somewhat....it could also be something in the ignition system that is breaking down and producing less spark energy when in hot ambient conditions....

Have you pulled * checked your plugs and spark plug caps? Since I don't believe our bikes have Iridium plugs I would try a set of those as well. Did you try increasing the CO settings?

Just a thought.

Hmmmm, I was taught in A&P school that a hot/humid day will in fact lower the air density (take more runway/airspeed to get off the ground) and make an engine run RICHER. Altitude does the same thing, as you climb, the air gets less dense and the fuel mixture goes richer. Of course the ECU should compensate for this automatically..... perhaps it is over-compensating causing a lean-out???

Well.... I remembered that backwards....you are indeed correct. I hate getting old and senile. :'(

Possibly just by removing your accessories was the cure. That's part of the reason I don't add them. Like side effects on medication. Sometimes the after is worse than before.

That thought crossed my mind but I had the vibes before I added them. Actually, I added the accessories to try and combat the vibes.

This is a bit of a shot in the dark, since I don't actually own one yet, but the XT660's and and BMW boys install a cheap resistor across the Air intake temp sensor to fool the bike into thinking it's colder than it is, so the CPU adjusts the fueling to be on the rich side. A friend of mine installed a variable resistor (R1200RT) so he could change it during the year. The thing with the resistor is you can add it into a plug and pull it (or switch it) in and out to check the difference quickly. I know the BMW uses a closed loop EFI like the S10.

You also have the option of buying a very expensive after market "device" to do the job on the BMW's with many hundreds of posts arguing that it's just a resistor with a bunch of components around it to look fancy.

[edit] (You just posted a response to this)...A few people on the Strom forums have had "Vibe" problems

If you are convinced that the farkles are not a problem, see if you can find out what the XT600 Tenere guys do and maybe try that. It would probably be a similar system.
I am sure that someone over there could help out who is handy with electrical diagrams and a soldering Iron.

I'd hate to see you take a big hit financially without trying something simple that costs very little.

Cheers

The only issue I have with vibes is the numbing of my right hand, no matter how loose I grip the throttle. I picked up a crampbuster for 10 bucks and still get the sleep mode in my hand a little later on during the ride just resting my palm on the buster, no grip at all. Funny thing is grip the left side firmly all day long with no numbing at all.

To see if it was my anatomy I rode (in safe mode) with my left hand on the throttle, got tingly enough to know its not me personally.

In checkin out the linkages and throttle itself the only assumption I can come up with is there is excessive play(gap) between the throttle grip carrier (whatever you call it, please advise) and the handlebar. I can wiggle the throttle grip up and down as there is a gap between the bar outside diameter and the throttle 'whatever' inside diameter.....

Does this observation make sense to anyone besides me?????? I understand there need to be minimal friction in the mechanism but this seems excessive and believe this is whats causing the buzz in my (and perhaps your) right hand......

I had the same issue with my right hand going somewhat numb on my Tiger 1050. Fixed it by changing grips to ProGrips 719's. I have these on the ST right now, but they are a little short, but useable. The stock Yamaha grips are just awful IMHO.

Same problem for me regarding the right grip on extended rides.

I have no problem tryin new grips (and will, thx for the info) but it appears to me that the underlying issue in the s10's case might be the throttle mechanism itself??????? Whatever the right grip slides onto is called.....

 

[GrahamD]

Might be onto to something there guys. I wonder wheteher it can be "tightened" as in less clearance, up a bit?

I'm gonna pick up some new grips anyways as you folks have suggested and here is my plan. Once I get the old ones off, take off the throttle and shim the bars with a few wraps of black electrical tape at each end of the mechanism to take up the gap but not bind the throttle. Slap on some new pillow type grips and hope for the best?????

Any other suggestions on the subject are appreciated.

For the best in vibration reduction, I have found foam type grips to be the best (although I don't really care for them), they do reduce the vibs the most.

I like the Pro grips, but prefer the 714 dual sport grips. I have them on all my dirt bikes and street bikes. They seem to soak up the vibes on whatever I put them on.

BTW, the thing they slide on to is the throttle tube.

In the S10s case, all vibes are not created equally. In the cases with the 3 bikes we know of where Yamaha gave the owners replacement bikes in South Africa, the most intense vibes were coming through the footpegs.

I would put these vibs in a different category than ones that only numb your throttle hand. I lost count of how many bikes I've owned that did that.

I have those on my XR! Good off-road grips for sure...now you want talk about vibs...that big 600cc thumper is one for sure!

I dont have any unusual vibes throught the pegs but it seems the throttle tube has excessive gap between it and the bar.... I cant get over 10 miles down the road without the hand getting numb which seems unusually quicker than any other bike I have owned. I did just order a set of the open ended progrip 719's and will try to take up some slop in the throttle tube when I install them.

Were the bikes replaced by yami you mentioned recent or some time ago?

 

[markjenn]

You're probably barking up the wrong tree with your "excessive play in throttle tube" vibe theory, but the idea to shim the bar with tape to reduce the play should work and will answer the question.

Vibration? Where? My Tenere is just swell in every respect. My 06' GS1200 vibrated a lot more. Used to get a weird vibe in the right foot peg on asphalt. Weird mon.Of course,BMW couldn't do anything about it. I've ridden the S10 1000 miles so far, most of it on western US dirt. It is an amazing bike. By this time on the GS I had at least 1 lightbulb burn out & the ABS pump blew up. Rear shock died sometime before 3000 miles. The S10 just keeps going.....& going..........& going. Jap city,the way motorcycling oughtta be. Love this bike. Wife does too. Wish I'd ordered 2 just case they become unavailable someday(like the Honda ST1100 did). Good luck with the vibes.Mine are all GOOD.

Interesting, hadn't read that. My pegs are so smooth, I took the rubbers out of the SW-Motech pegs, don't need 'em.

Yesterday when my bike was running the smoothest it ever has, I was still getting some vibes thru the pegs. Not enough to be a deal breaker but the pegs seemed to be worse than the handlebars. When it was misbehaving in the past the bars bothered me more than the pegs. However, your feet have more protection from vibration because of the rubber in your boots but it still bothered me enough that I put gel insoles in my boots to isolate my feet even more.
