YAMAHA XTZ 750 / TDM 850 SUPERTENERE 👌 SIMPLE TRICK.. TO ACCELERATE BETTER! 😉

[@garyhoward4064]

I am trying to understand before I do this on my XTZ. So, if you remove the piece(s) in the tube, there will be more depression and the carburetors will open faster. But is it not the same as simply opening the throttle more and faster ?

[@VolkerVolkach]

Hi Gary, thank you for this answer..✔👍 Ok, i try to explain, what i think about this: In my opinion, the negative pressure is built up "faster", which causes the slide to open faster, which is attached to the diaphragm. I have since read that some Yamaha workshops always remove this. But whether this is so, I do not know. But, I have done so on all the XTZ I had, there were 3 over time, as well as on the TDM I also drove. I never had a problem with it, and am sure if you have the feel for it, you notice the difference clearly. I was until recently of the opinion that most XTZ drivers know this, and was surprised to find nothing about it on KZbin. Therefore, the video. It is in any case no big deal and you can undo it at any time. Damage it can not in my opinion. And it also does not change the basic performance. Only the response behavior. I have noticed the strongest at Wheelis, I could drive with the XTZ partly 300-400 meters on the rear wheel, even switch. Up to about 80 km/h. First has nothing to do with it. But it just went easier on the rear wheel, partly in 2nd gear with clutch and matching speed. Hope that helps you to assess further. But the effect is not so great in the end..just noticeable! 😉

What he is trying to say, imagine a pipe, water pipe, airpipe, doesn't matter, when you have one and you push or pull air or liquid trough it, if theres a sleeve or a joint that narrows the pipe you get faster flow but lower pressure along that lane, so removing the sleeve you effectively remove that problem. Okey it is not that easy. Those are the ventilation hoses on the carb, so you are effectively opening the ventilation hoses more, you evacuating the gases better, bigger volume of the gasses at a time, allowing your engine to breathe better, hence the bike feels more responsive on lower gear, but that can lead to more oil leaks * if you are doing that tune the carb for slightly higher fuel and air intake to prevent it from choking on a cold start * but if you do that you will waste more fuel, however you will get some power and probably more oil leaks [ depending on how well made the carb is made ] Ultimately it is your choice. also a note: too much pressure handicaping the piston downwards movement

[@garyhoward4064]

@@RongYaoElk Thanks. Actually the reason I am interested in this mod is because on my bike the throttle response between higher idle and idle is not smooth. To clarify, when I am at 10 mph in first gear with small throttle opening and want to reduce to say 5mph, the engine will jump and cut directly to idle with nothing in-between. And vice-versa. Makes low speed drive a bit jerky.

[@brenkeenan8892]

Your English is fantastic!! I will check the pipes on mine at the weekend. Thank you.

[@VolkerVolkach]

Thank you! Good luck!.. 👌If the sleeves are no longer there, a previous owner may have already done it. But you will see it! 😉

[@janvan5872]

Thanks a lot for the effort to do this in English I am also a XTZ owner from 1992 and have never known about this trick. I will try to do as soon as posible.

[@VolkerVolkach]

Thats cool!👍 My first Super Teneré was the white/blue one, from 1991..✔😎 This was the first one, i tried this out. In my opinion, it is clearly felt. But that is certainly subjective, perhaps not noticeable for everyone.🙄 Have fun trying it out! Thanks for your feedback!✌

[@robplazzman6049]

English is fine ! Just bought one last week. Runs well but needs tidying. Too old for sports bikes now so this one’s a keeper. Hoping it will take me from the U.K. to SouthernGermany, Romania and Ukraine one day.

[@VolkerVolkach]

Hi Rob, that's really cool! ✔ - You have made a good choice. 👌The motors have a long service life. I remember a test from the 90s. I don't remember how many kilometers the Tenere had run, but there the cylinders and all wear parts were removed. I think after 80,000 km. There was no real wear recognizable. Even the valve clearance still fit very well. If your new XTZ already has many KM, or you are thinking about another engine. The one from the TDM fits very well, or the TRX type. That has often been rebuilt, gives reserve, and then yet a little more power as the standard. 😎 Maybe you find something more in this forum: tenere.de/index.php/board,34.0.html?PHPSESSID=0dd86df31638311c35ad30115e0f3052 Wish you always good trip with it! ✌✔

[@powertrip1050]

Mate, your English is excellent. 👍I had a Super Ten back on oz in 1996/7, and I am on a search to pick up another one here in Europe. I have just left Germany after 6 years and moving to Croatia, so maybe I will see you out on one of the TETs one of these days. Thanks for the tip, it was great!...and yeah, your English is better than my German. 😁

[@VolkerVolkach]

Perfekt! Thx for Feedback! Beste Regards! PS: 4 weeks ago, there was one in "Kleinanzeigen" with only 12.000 km. Looks nearly new! He wrote, only the carburetors are not ok. Unfortunalety i wait too long. I wrote him, after i watched it for 2-3 Weeks. I decided to buy it.. Just this day, it was sold.. hmm.. s..🤦‍♂ happens.😉

excellent trick video. your English is great - fully understandable :)

[@VolkerVolkach]

Thank you! This makes courage to add more videos in English!😉👍

[@spanish-sun]

Your video is fine but really it's dangerous because dirt can enter the carburators and really does not improve performances. A lot of motorbikes have this installation.

[@bubba3ld]

Thank you for the video. I definitely check mine on this weekend.

[@VolkerVolkach]

Good luck! In some cases, if you are not the first owner, it's always done. But it's not much work! regards!

[@krzywonos34]

Your English is fine. You were very easy to understand. What are these houses that you modified? Are they vacuum hoses?

[@VolkerVolkach]

no, i think they let the air come in, when there is negative pressure in the carburetor system. And when the tube is smaller, for reason of the sleeves, then the air comes more slow in the carburetor.. maybe ..

[@polini22]

Hey! Zeig unbedingt mehr tipps und tricks zur super tenere! Ich hab kurzlich genau die gleiche erworben wie du. Ich frag mich ob die ( für die schweiz) von werk her gedrosselt sind.

[@VolkerVolkach]

Hi, ich denke die beiden Hülsen sind sicher drin (oder gewesen).. Aber es bringt keine Mehrleistung, nur besseres ansprechen! Trotzdem angenehm.✌ Ich habe das an meinen ST in den 90ern schon immer gemacht, fand aber nirgendwo mal einen Hinweis, das es auch andere schon getan hatten. - Es gehen nur die Schieber schneller auf, bei "aufreißen"..😇😬 Hab noch ein paar alte Clips.. Kommt noch was die nächsten Tage.. Viel Spaß mit Deiner Neuerwerbung!

[@pavloboiko8522]

Where those sleeves are leading to? On my bike, i don't have the second part after the filter. Are they connected to the engine or just outside?

[@VolkerVolkach]

They are going just outside, i think betwenn the engine and the swingarm or the frame.. not sure..

[@milospopovic6978]

What is the benefit of these mod ?Better response on acceleration(more air-more power) or higher speed ?

[@VolkerVolkach]

hi, no higher speed, only better responce on acceleration. If you try it, i think you can feel it.. the engine just somehow hangs better on the gas.. it gets not more air, only the gas slide opens faster..

[@alanwilliams3677]

Hi Volker. Interesting vid. Wouldn't this alter the carb setting, causing engine to run weak? I've got a TRX which has the same filters. There is a slight lag or hesitation when pulling away from stationary. I wonder if this could be why? Spark plugs are blackened though, which suggests engine running rich.

[@VolkerVolkach]

No, not to weak, i think exactly like it should.. 👍.. The reasons of this lag could be the narrow tube. Try it, i mean the TRX could be the same. Many people use this engine in the XTZ. The TDM have the same carburetors. And check the needle, maybe they are narrow in the middle after the use over the years. They move in the noodles, and this could be a reason too, maybe...

[@alanwilliams3677]

Hi Volker. I checked and there are no "restrictors". Either they weren't fitted to the TRX because it was meant to be a sports bike, or someone had already removed them. The British bike magazine, Classic Bike, for this month (September 2023) has a feature on the TRX, and claim they run too rich, and that the standard main jet of 142.5 should be swapped for a 137.5 and the air screws should be "leaned off" by half a turn. They also advise experimenting with the needle position. I don't know about the TDM, but the TRX is a real labour of love. Thanks for replying.@@VolkerVolkach

[@VolkerVolkach]

Ah, Ok, i unterstand, in the TDM and XTZ, i used the needle in the second position from top.. the "clip-ring" (right?) is in the second notch..@@alanwilliams3677

[@sergius8223]

What about fuel consuption? Is it bigger or it is less??

[@VolkerVolkach]

There is no noticeable difference, if at all, when driving many short distances with strong acceleration. The performance remains unchanged. Only the "response behavior" is better.✌

[@VolkerVolkach]

Non, j'ai eu plusieurs XTZ et TDM au fil du temps. J'ai toujours réglé l'aiguille de l'injecteur de manière à ce que cela convienne. Généralement dans la deuxième rainure à partir du haut. Important ! Beaucoup de gens pensent que l'aiguille de l'injecteur ne fonctionne pas. C'est faux. L'aiguille s'use à cause du flux d'air. Le mouvement qui en résulte rend l'aiguille plus fine au milieu. Elle s'use dans la buse. Le mélange n'est alors plus correct. J'espère que le rapport de transmission est bon ! La bougie doit être légèrement brunâtre.😉

Ok, i think i change to english. Maybe you mean misfires in the engine, or backfires.. So I'm not a two-wheeler mechanic, even though I try to do a lot of things. 🤔 I think this may be due to wrong mixture... too lean maybe. Misfires and enriched mixture in the exhaust... I've also read about deposits on the piston causing "glow ignitions"... but in the end I don't know. Sorry...🤷‍♀️✌
