2017 vs 2014

[pooh and xtine]

Just swapped my 2014 for a 2017 and the new one pops and bangs on the overrun much more than the old one did. Does anyone know if Yamaha have introduced more secondary air induction and/or changed the engine mapping, for Euro 4, perhaps? Or it could just be my imagination or the long term fuel trims building up - I've only done 300 miles so far.

"overrun"? If you are referring to over rev, I don't do that enough to notice anything amiss. If you are referring to using the engine to slow the bike, I did notice some popping/backfiring when the bike was new. I have not noticed it recently, and I often engine brake. I do have a '17 ES.

My 2017 pops on the over run... More than my 2014 did..

I quite like it..

Not as poppy as my Tiger 800 though..

Accepting the 2017 map is likely to differ, I see no reason why there should be any undue pops & bangs on a closed throttle, assuming you are on the OE standard pipe. Still, she really needs a few more miles before drawing any conclusions IMHO.

Is the idle speed correct - 1050-1150 rpm. If so, maybe a slight air leak somewhere, throttle cable adjustment, TBs or the TPS - perhaps your dealer can check it out at the 600 mile service.

The new bike is EURO4 compliant, meaning it has a slightly different ECU map. Getting the ECU re-mapped ought to make a big difference.

Popping is an indication that the TB plates are not completely closed, in general terms. With stock exhaust, this shouldn't be noticeable.

At this point though, your bike is too new to make any judgements. Certainly too new to decide if you want to flash the ECU. Ride it for a few thousand miles and see how things shake out. If it's really popping and banging quite noticeably, something is off and you should discuss it with the dealer.

I have a 2016. I noticed deceleration popping from the first ride that wasn't there on my 2012. It annoys me tremendously. I recently had it flashed (Reflashed?), and it is all gone. Any gear, any revs. Music to my ears. Just another benefit if getting it done. At least on my bike. Nobody else mentioned it, so I can't be sure it's part of the package all the time. Maybe AVC 8190 would know. I think that was his name here. He did my ecu.

Many thanks for the responses - it's good to know that I'm not alone in noticing a difference. I don't dislike the noise, in fact the irony of Euro 4 measures making the bike slightly more anti- social makes me chuckle at the folly of meddling autocrats! I'll leave it for a few thousand miles and see how it beds in.

I too went from a '14 to a '17. I noticed the '17 to be much peppier and to feel better than the '14 and have always attributed it to improved mapping.

Now, earlier this year, several of y'all told me there was no difference between the '17s and other Gen 2s. My bike was hitting 140m.p.h., and all I heard was that my speedo was in error. I suspected that there was a change made to the '17s after reading everybody else's descriptions of their bike's performance. But, I have never ridden any other Tenere, so I had nothing to compare it to. All I knew was much better than what I had expected. Those of you with '17s, who have driven other Gen 2s, are now confirming my suspicions. Thank you. ::012::

My "New Tenere" Has done over 2000 miles now... Still pops..

My Tiger 800 with a standard can pops on the over run... thats done 24,000 miles..

It's a characteristic on the Tiger800's.. Maybe with the new map on the new Tenere its a characteristic..

I've just been looking at the Yamaha online parts catalogue. Compared with the 2014, the 2017 has a different throttle body assembly, air intake pressure sensor and some additional intake pipework. The exhaust pipe assembly (manifold and cat pipe) is also different. In addition the 2017 has all of the charcoal filter canister gubbins under the fuel tank - part number 5PX-24170-00, plus all of the associated pipework. If you factor in changed engine mapping to suit, it's no wonder it feels (and sounds) quite different to ride. It does seem to have a bit more get up and go, even though I've not taken it above 4,500 revs so far...

However, fuel consumption is 6mpg down (and I'm riding gently whilst running it in), although this may improve with the miles. And in traffic, the heat coming out from the engine under my thighs is way more than it was with my 2014.

That's interesting! Thanks for the update and the changes on the 17 model.

Is that the UK or USA spec as the some of the american bikes had the charcoal canister for the Californian emissions.... Maybe one of or friends from over the pond can verify.

Mine does better on the fuel economy than my Gen 1..

I hadn't thought about it but there was some popping on decel on my 2016. Stock exhaust and it wasn't loud, I just kinda noticed it. Now that I think about it, it has gone away with the reflash (AVC8130).

Yes, it's UK spec - I guess in the US you've had California EPA canisters for a while. In the UK there is no 2016 model as such - it's just the 2015 model, which had the same intake and exhaust components as the 2014 Gen 2.

I've also noticed from the 2017 owners manual that it has gained a diagnostic socket located close to the accessory plug to the right of the battery. This seems to be part number 2BS-81860-00 in the parts catalogue and it attaches to the throttle bodies somehow. Gawd knows what that is used to measure or monitor, but Euro 4 includes a requirement to be able to diagnose whether emissions stuff has been tampered with or disabled, so it could be that (i.e. an on/off switch to tell whether you've done a canisterectomy!).

Yeah, I had stock can too, which the popping from being too loud. However as I mentioned it still bothered me. I Think it indicated that it was running too lean. It was much more noticeable in "S" mode rather than "T" mode. Yep, the flash took care of it.
