|Mialem to samo. Jak poszperalem na forach w US, UK i DE to wszyscy typowali TPS. W Suzuki w Zurychu, podlaczyli pod komp, wyszlo, ze wszystko w porzadku. Pozniej, ale dalej spadaly obroty ponizej 1000 i gasl. pozniej sie przeprowadzilem do Niemiec i Suzuki Essen, tez pod komp podlaczylo i tez wszystko w porzadku (TPS tez dzialal poprawnie).
Zeby zrozumiec problem to polecam spojrzec jak wyglada TPS w srodku:

Jest to taki suwak ktory przesuwa sie po stykach przez co zmienia sie opor. Moze byz tak, ze jest jakies male pekniecie gdzies na tych stykach i na przyklad w pewnych warunkach (nagrzanie, ochlodzenie) powoduje, ze nie ma styku. Wtedy komp zaczyna wariowac, bo dostaje zly sygnal. W normalnych warunkach (w serwisie) wszystko bedzie w porzadku.
Problem opisalem tutaj:

So far I was just reading your posts. Now I decided to write something too. I have the same problem with stalling of the engine when pulling the clutch (going to a stop, changing gear, etc.).
Suzuki dealerships in Zurich, CH or Essen DE, could not find the solution. All the sensors are correct, everything is beautiful, bla bla bla. However bike was still stalling.
Just recently I met a guy, who is a motorcycle enthusiast with some mechanic background (works for Opel). So I will describe here what we have done to solve the problem.
First we removed the tank and the filter box. Doing this enables you to see the throttle shafts with the throttle plates inside. Then we went into dealer mode as described previously (http://www.vstrom.info/Smf/index.php/topic,7061.msg82938.html#msg82938). At the screen was shown "-C 00" which means that TPS is adjusted properly. Then, normally if you will turn and let go the throttle on the handlebar the "-" goes up, and then immediately should go down. However in my case, when I did it (especially slowly) it stayed up (!). At the same time we have noticed that the throttle plates in the shaft do not close completely. I mean, it looks like they are closed, but there is still a small gap through which the air can go. This causes that to much of air is flowing and the mixture is to lean. At this moment it was just enough to "tap", touch or gently push the TPS from the bottom to provoke the throttle plates to shut completely.
This gave us a clue that it is either TPS (as most of you guys already mentioned), or some problem with the mechanism that simply shuts the throttle plates in the shafts. So before exchanging the TPS, we decided first to clean and lubricate the system. All the the springs and joints between the rods that open and close the plates of the throttle. Also the place where the lines from the throttle from the handlebar come (on the top left part of the engine when you look from the top). After many movements of the throttle on the handlebar we reassembled the bike and went for a ride. I did around 50 km on some small roads trying to artificially induce the problem. So far without result. It runs properly.
I will keep you posted if the trick with cleaning and lubricating was not enough. If it will happen again, then I will go for the TPS.
I hope that you can understand what I have described. If not then go ahead and let me know.
I pozniej drugi watek ze strony 8, gdzie opisalem juz rozwiazanie:
in November last year, I have described the reason of the stalling that I have observed in my WeeK7. At this time, the only thing I did was to clean and lubricate all the elements of the air intake system (levers, joints, etc.). However as I rode in March this year to visit my friend in Belgium, my motorcycle started to stall again after a longer stretch of riding. From this time on it was happening again from time to time. Sooo, at the end of May I have exchanged TPS (primary). From K7 on, both TPS sensors (primary and secondary) are the same, except of different localization and angle of installation. In the first two weeks of June, I did 4100 km through Alps to South France, Italy, Sudtirol, Switzerland (mostly mountain passes, but also some stretches of HWY in Germany), and during this period engine worked perfectly. I really do hope that this exchange of TPS fixed the problem. I will let you know if the problem comes back again. Cheers, Greg
Wiele ludzi mialo to samo.
Tu jeszcze jeden przyklad:
Po wymianie TPS w maju tego roku, przejechalem ponad 15000 km i wszystko gra.
Jak cos to pisz na priva.
