Regarding the recommendation to adjust the throttle slack. I don't see any adjusters at either end of the cables (at the throttle assembly or at the throttle bodies). There appears to be an adjuster in-line on the cable, but on my bike it is covered by a vinyl sleeve that appears to have been shrink-fitted and so won't easily slide out of the way. I don't think I can access the adjuster without destroying the sleeve.

How have you all accessed the adjustment?
Its surprisingly easy. I video'd it here https://vimeo.com/231145481
Loosen lock on right, thread adjuster to left, tighten lock to it.

Well, that begs the question of how many miles do you have on your Super Ten? ;)

I've had a new '12 and now a '15 that I got with 3k on it. Both smoothed out around 5-6k and just have less vibes, fewer efi oddities and smoother clutch asction after that period. I didn't need to get used to anything when I moved from the '12 to the '16 except CC.
14,000 miles. It runs and feels the same as the day I bought it. Even after doing the improvements listed in my previous post it still has the clutch shudder and not perfect low end response. I have several other bikes in addition to the 2013 S10. They all have a different "feel" to them. Just saying an EFI bike especially one with throttle by wire takes some getting used to especially for those of us who have never owned one before. Also, bikes with hydraulic clutches have a different feel to them compared to the cables. My first EFI bike was a 09 HD superglide. It was like riding a carbureted bike without an accelerator pump.

I don't know what to tell you. You're sensitive to certain issues, like the "not perfect low end response" and the clutch. Neither of which I notice at all. So I can't really tell you that you would notice if you haven't noticed changes. But I'm not a guy that spends money over little things either. I just ride the bike. Every bike is different and has it's own personality. I'm comfortable with what my Super Ten offers me, for my riding. Others clearly enjoy the changes that the flash brings to the personality of the bike. No harm there.

Of course, I only have the one bike to ride, so I'm not comparing it to other bikes in the stable. On rare occasions I ride the wife's GSA LC, but that doesn't compare favorably, for me.

I guess I am somewhat of a perfectionist when it comes to my bikes. The original poster describes his bike 's low end as horrible, I've described mine as not perfect. Even after making the usual adjustments there is room for improvement. Maybe a flash will get me there. This topic comes up all time on this forum or maybe whenever someone buys a new bike, so there's something to it. When I bought my S10 in June 2015, I joined this forum and got lots of good info about improving the low end response. The original poster can try some of these same adjustments to make his bike better.

When you are a well seasoned rider like this poster seems to be (and a lot of others in this thread recommending a flash), you expect bikes that are quality tuned from the factory. To clarify, as the OP (me), I have ridden many bikes, last was a 2006 wing for 138k mi in 8 years solo across all lower US and have never felt something so "horrible" as the low end on the S10. I say there is much room for improvement. To get a stock bike and have to adjust a throttle cable is unheard of IMHO, ok, simple adjustment that helped np. To get a stock bike that the low end acceleration feels dull for the first 1/3rd of the the throttle pull, feeling like your air filter is clogged and the bike is getting no air, is unacceptable. Then in the upper end it opens up all of a sudden and feels like a 1200cc bike, wtf. Poor engineering. Again, love the bike for what it is, but the flash is a no brainer in my future.

I also ride a GL1800. Yes, the Honda is more forgiving, less abrupt throttle response, whatever. I love them both. I find the Super Tenere perfectly fine in the way the throttle works, but maybe I'm just not as sensitive as some. The way mine runs and the fuel mileage it gets, I would worry of fouling up a good thing with a flash. I always get 50mpg or better, and have even seen 60mpg.

The reason this comes up so often is that most people have never had throttle by wire bikes. Many of the biggest complaints are people that come off a carb'd bike and hop on the Super Ten and can't ride it smoothly. Its all about throttle control. If said rider is a brake in, throttle out rider too, it's a tough learning curve. It's not that they can't get there, just that it takes some practice to learn to ride the bike as smoothly as they thought they did the previous bike.

Every Yamaha I've ever owned, (4 now), needed the throttle cable slack adjusted. In part simply because I prefer less slack than the Yamaha FSM specs. I've had to re-adjust it after having the valves adjusted because an over eager tech adjusted it to the factory spec when doing the re-assembly.

Expectations are another issue. The parallel twin with it's very long cam chain and piston stroke is not going to be as smooth as an inline four or big six.

Thanks, that worked. On mine there was a tie-wrap biding the two cables together that was in the way. I had to cut it off first to allow the sleeve to slide back. Don't see the point of the tie-wrap so am going to leave it off.

I come from an older Honda Transalp this spring, the Transalp had no injection, no ride by wire, really basic. And even that it was from 2006 the engine was almost the same from the late 80'. (yes it grow from 600 ccm to 650)
Anyway, I dont have any problem driving on the new 2017 S10.

There was a litte thing i noticed the first time I really turnded the throttle all the way, there was a small "gap" in power delivery, but it might have been the TCS, because of lifting the front wheel. But I never found out for sure, because I was sure I had the TCS turned off, on time and I still felt it... I tried onlce to give full trotttle, after this, and there was nothing, so I just don't give it any thoughts now. (yes, I drive very much like an old man :))

But my dealer also told me, that at least the european 2017 model have a different mapping, because of EURO4.

There is one thing however, that the S10 still do. When starting up from cold, I have to be very slow with the trottle (not turn the trottle fast), if I do that, the engine will not go up in rpm, but sounds like it get to little gasoline, or maybe to much. If I continue to do this, the engine will stall, and have a little problem starting again, have to run much more with starter, and give trottle, for kicking it back to live.
My S10 have now 5000 km (3125 miles) on the ODO.

While my 97 carb'd Magna is MUCH smoother on the throttle,
I've been riding my S10 in 'sport' in traffic this past week and while it's not anywhere near the Magna, it's easily doable.
But I still might get the throttle tamer or re-flash it in the future.

HI,i purchased a new 2017 es model in june and the only thing i didnt rate was the bike in sport mode,twitchy mode,after many hours on the internet i decided to purchase a BOOSTER PLUG it takes about half an hour to fit and all it does is fool the ecu to think the bike is running cold ,so in turn the ecu richens it up{more fuel) i would say its improved it by about 80% i ride in sports mode all the time now. The only downside is the outside temp gauge is always showing - temp which is not really an issue,there also doesnt seem to be any difference in fuel cons,well worth fitting ::015::

Does anyone really know if the US bikes meet EURO4 standards? On paper the EURO4 stuff looks a lot like US California emissions, but I have no idea how close the mapping is, only noticed that both are running charcoal canisters with vapor recovery systems.

As per excerpt frm their website:
"Note: The Yamaha XT1200Z series is using the same temperature sensor for the fuel injection calculations as for the temperature readout in the dashboard. (Most other brands have seperate sensors).
This means that your dashboard display will show 20°C / 35°F lower than actual ambient temperature when you install the BoosterPlug.
There's no way around this, and it's probably not an issue for most people, but we want you to be informed about it."

So can I say that as my meter is selected to coolant temperature display, if fitted with the Booster Plug, the reading will be +/- 20°C therefore, it'll affect the radiator fan activation @ 105°C too?

pardon me as I stay in South East Asia where the climate is usually hot & humid & activation of the fan is a norm here..

Looking at this product because of:
- Improving & softer throttle response.
- Harder acceleration.
- No more low speed surging.
- Stronger and more reliable Idle.
- Reduced Puffing in your aftermarket exhaust.

I have the booster plug installed. It does not impact or change the coolant temperature reading. The ambient air temperature reading will be 20C lower than reality. The coolant temperature reading is still accurate.

ah okay, thanks.

that was what making me tinkering.. ;)

Is there any other Pros & Cons that you can share here too?

I own a 2017 S10 California model. From the first day I owned it I experienced occasional stalling, rough idle, and jerky throttle response. In my opinion lean fueling symptoms that are extenuated because of so little flywheel effect of the Tenere engine. I searched the owners forum and first tried the 3/4 turn out R. throttle body adjustment and TB sync. This helped but did not cure the symptoms. I did note that the problem was reduced as I added miles to the motorcycle though performance was still not satisfactory. Again searching the forum one contributor mentioned the BoosterPlug (thank you!!!). I went to their website, viewed their claims and for $160 gave it a try. After a simple plug in installation the stalling, rough idle and jerky throttle response issues are totally resolved. If you are experiencing similar symptoms to mine, I would give the BoosterPlug a try.

nope, not interested in fine tuning exhaust or getting more power, just taming the throttle. Thanks for advice!
Touring mode for low speed riding, sport for all else. Sync your throttle bodies and that is it.

I am a fairly experienced rider and I agree the low end throttle response is horrible on this bike. Way too sensitive and way too much engine braking when rolling off the throttle makes this machine hard to control at low speed.

I have my ECU flashed and it helped majorly. It is still not perfect but certainly acceptable now. If I could do it all over again, I would buy the G2 Throttle Tamer first and see if that improves it enough for you to be happy. If you still want more, then have your ECU flashed. I used our local guy to flash my ECU and I highly recommend him. Send him a PM at avc8130. I have heard good things about ECU unleashed but that is about all I can tell you.

::026:: I use a throttle tamer with a 400 series cam and it helps, not quite perfect yet, but a big improvement.
