so how many miles tell...............

Thanks, Karson...

But the specific illustration/diagram I was referring to was the one on page 13 labeled "Cylinder Firing Interval", which best shows how the firing interval and crankcase impulse is nothing like a single-cylinder engine.

Funny, too... As I have heard that misconception before, that the power delivery or firing order of the Super Tenere is somehow like a single-cylinder... maybe even somewhere here on the forum... but nothing could be further from the truth. It's nothing like a single, nor even like the normal 180-dgree or 360-degree parallel-twin, but much more like a V-twin.

Now I know where I read it !! From the Yamaha web site, under features / technology: "The 1199cc parallel twin liquid-cooled engine features a unique 270° crank for superior traction because both pistons fire so closely together. It’s almost like having a big-bore thumper without the uncomfortable vibration."

That's far cry from:

"Another thing to keep in mind, since I don't know what bike you were riding previously, is that this bike has a 270 degree crank, and was designed to emulate the power delivery of a single cylinder bike - but using two cylinders. So it has that "thumper" vibe and power delivery, which is nice in the dirt, but can be an issue on the freeway."

Notice how Yamaha clearly states it is designed so it does *NOT* have the "uncomfortable vibration" of a single-cylinder engine...

V-twins actually have somewhat superior power characteristics and delivery for dirt use, which is why Harley XR750's dominated dirt-tracking for decades, and also why the only engines to currently challenge their flat-track dominance are Ducati V-twins and Kawasaki parallel-twins with odd-firing order cranks. There is definitely an advantage to having some long time-intervals between firing impulses (like in a single), but a single has the inherent disadvantages of having the piston completely stop and then have to restart at the end of each stroke, with nothing to help it continue rotation other than stored flywheel effect. OTOH, a proper twin has the other cylinder and its firing impulse to help it overcome this stop-start issue, which is the whole theory behind Yamaha's "crossplane" to try and avoid this "inertia torque"...

Again, take a look at page 13 of Yamaha's own "XTZ12 Super Ténéré Technical Orientation Guide", as well as some other sources on the 'net. Lots of good info out there on 270-degree parallel-twin cranks.

Just FYI...

I think you are right, that it pulses like a 90 degree v-twin. But going back to the original poster - whether the bike has thumper or v-twin characteristics, it certainly does not have the smoothness of an inline 4 or something like that, which may be why he has an issue with the vibes.

 

[Ramseybella]

That was my first impression it felt like a big Thumper or a giant Mini bike; I did the CJM and now it feels like a Ducati hooligan bike on the street in S mode, like a super charged tractor in dirt with the T mode. ::008::

 

[Gee-Tee]

Mine doesn't vibrate at all, there is a wonderful gentle throb but nothing more. I know people that grip the bars so tight their hands go to sleep no matter what kind of bike they ride.

OP here my other bikes are a Moto Guzzi Norge Vtwim 1200 CC 2 valve (old air cooler VW motor) And a 2011 Kawasaki Versys that I traded in on the S10....And I have never rode an inline 4 in my life......My biggest compliant is the motor harshness from 3800 to 4800 rpm (cruise rpm) I checked the TB's today and they where spot on....I am guessing this is a fueling (emission issue though that area)....Or could it be something else....I keep hearing that at 6000 miles the bike changes and smooths out a bit....

Question if I temporary do the CJM mod will it give me a good idea if a reflash will smooth the bike out....

LOL, you came from a Stelvio, not a ZX14, that's why you think it's smooth.

My Super Tenere got noticeably smoother and smoother as the miles piled on (it has over 34,000 on it now), and yes, 6,000 miles was one of the more notable spots along the way where there was a more apparent change.

That said, I always thought my Super Tenere was quite smooth for a twin. Perhaps not as smooth as the two Kawasaki Versys I previously owned at first, but much smoother once well broken-in, without any of the annoying high-frequency *buzz* both the Versys had. But I should also say I've been riding since 1970, and back in those days we had some bikes that *REALLY* vibrated... Any British twin, any H-D twin back then, Honda's twins (or any Jap four-stroke twins for that matter), etc., etc., etc. Bikes are so much smoother now they all feel damn near like magic carpet rides to me. OTOH, I like twins... A lot more than inline fours, to be sure. I like the way a twin *feels*, and the gentle, low-frequency throb they produce is not unpleasant to me at all.

But I have to say my Super Tenere feels almost turbine smooth at cruise speed... around 75 to 85 MPH, anywhere in the 4,000 to 5,000 RPM range. Mine has no "harshness" to me, at all, in any way. For me it's just wonderful there. Note, I have stock bars, stock grips, with Rox "1-up, 1-back" risers, and stock intake and exhaust, with an ECUnleashed Gen 2 re-flash.

As for the CJM... It's pretty common knowledge around here I've never been a fan of it. IMHO it will do nothing to help smooth the bike out. That said, I'm sure others will say otherwise. I think you may want to look elsewhere for a solution, but who knows? It's a 20-cent mod that's completely reversible without any necessary alteration so it certainly won't hurt to try it.

All riders have different levels of vibration sensitivity, and often it even varies bike-to-bike, so no one here may have the *perfect* solution for you. You may just have to try some various ideas and options to see if you can get it where you like it... But miles do seem to help for most folks, so one thing you can do is ride, ride, ride ::001:: and see if that helps!

Yea, mine is smooth as silk, and I'm running K60s with 8k on them. Only problem I have is a super harsh suspension. Need to get my front forks rebuilt.

i been having issues with my TPS started around 12000 miles really gotten bad at 22000 miles . when acting up i get lots of vibration in my hands and bike doesn't run as smoothly the way iv been able to fix it is before i start the bike turn key to on position twist throttle all the way open and let it snap back closed five or six times .

is that something to do with the tps reset....What does that do....gonna go search tps reset now

 

[carrot]

haven't heard about a reset i had this trouble with my r6 i could ride it some times and it would would run great then next time it was running rough i did everything from changing all the coils and valve adjustment new timing chain and tensioner nothing worked what i found out was that the TPS are like a old style radio volume nob if u leave it in one spot for a long time it will start making crackling and popping sounds when you go to adjust it. buy working the bikes throttle from closed to open several times before you start with key in on position it seems to wipe sensor clean i do this every time i ride i now can tell when its acting up in just a few seconds in the ride. im going to replace the TPS on my 25000 mile service and going to look inside the TPS to see what it is actually doing . zero vibes when its working .

 

[Ollie]

Sorry if this is a little off topic or old hat to you more veteran riders, but I got a lot out this article.

http://www.totalmotorcycle.com/school-SectionSix.htm

I'd also love to see some links on info regarding 270 degree parallel twins.

 

[Rasher]

I had more issues with my last four cylinder, it felt smoother, but the combo of high frequency vibes and weight on wrists gave me numb hands.

No issues on S10, although not as smooth as a four cyclinder the lack of weight on wrists, and reasonable smoothness for a twin (a lot better than my old GS) works well for me, I can feel it is running, but no problems.

ECU-U flash did make it noticeably smoother as well.

 

[Red dust]

Hoped that the ECUnleashed flash would make the biker smoother (less vibes) but it did not however it did make the gear changes smoother so no more head banging from the pillion and of course got rid of the restrictions in the first gears plus a little bit more torque in the mid range so in that regard it was worth the $.

Think I done a lot of modifications to make it smoother which has failed after spending a small fortune but still got some hopes that an eventual addition of Vibranators, Rox anti vibe risers, thick (double?) foam grips will help, wonder if I should fill up with synthetic oil or keep riding with mineral oil? Do not really want to go the header way since I already tuned the ECU according to my current mods but if I have to I will get the headers, re-tune ECU and maybe even a Power commander. If that will not help I give up and sell the whole lot and wait for a future SMOOTH adventure bike or get a 6 cylinder Gold Wing :-I, some people might say: it is a bike and it will vibrate and I would say in this day and age it should be most likely possible to make a smooth as long touring adventure bike, why not?

For a big twin it is pretty smooth, but no way is it smooth compared to some engines. You sound like you are primarily a road rider because this bike is smooth by on/off-road capable bike standards. You should probably consider a Triumph Explorer or Honda Crosstour. Both of them are more street biased but have smoother running engines that may offer you what you seek.

 

[Red dust]

Maybe you are right but I do not think I ride much less than others on dirt roads or worse roads. Does still not make any sense to build a bike that so many experience more than necessary vibes.

Did buy this bike since it got good reviews for off road ability and on other road surfaces and yes I am mainly a road rider since I use it more than 50% for normal roads but I honestly do not know/heard anyone that use this bike mainly for dirt. It is a fantastic bike on our Australian pot hole and many of our dirt roads but that does not mean it should be uncomfortable to ride between the dirt roads, does not make sense. In the beginning I thought it was only me that complained about vibrations but the person that started this thread and numerous other owners of this otherwise great bike have the same/similar issues.

My R1 vibrated quite bad but after some engine mods and tuning it became very smooth. My Suzuki B-King is not too bad but even that one became better after modification and tuning that is why I thought spending some money on mods & tuning would help the ST but failed so far.

My experience so far is that my bike smoothed out noticeably by about 10.000 miles. But I never felt any vibe issues (Versys was way buzzier). This summer I bought a cheap pair of mesh gloves while down south, and immediately started getting the finger tingle going on. Bought a good pair of gloves with palm padding and the problem immediately went away.

this bike is way buzzier than may Versys ever was... Anywhere from 3800-6000 rpm I could scramble an egg by setting the bowl on the hand guards....and resting ur fingers on the levers will put the tips of ur fingers asleep...and after 90 miles my palms are sore and tingly...There really is something not right with the bike....I think I have got one of the badunits that Yamaha has washed its hand of....Lucky me

[carrot]

have you checked your tires balance maybe out of round ?

 

[Red dust]

Actually thinking about looking at other bikes since my hands are too sore to ride it.

Will get bar risers, foam grips and maybe Vibranators and some more miles on the clock and if that does not help my girl has to go :-(((
