I wish you all the best but keep your horses back. I do not know if this will be the solution to your problem. Generally it seems that all Yamaha repair centers just following the direction from service manual which provide step by step solution diagram, based om the error code. Above I provide a link from France. Yesterday night I had a look and it seems that even throttle body replaced, issue has not been solved (based on google translator). It seems to be a problem that affect day by day more owners of GT version. In the French link, there is a vote if your motorcycle if affected or not. So far, if I recall well, it is around 40% of owners affected with this issue. I really hope that your issue will be solved. Otherwise we only need to wait about official announcement / recall from Yamaha, if any 😟

By the way, for the ones who speak French (unfortunately I do not and I am trying to understand via google): https://www.mt09.net/t14472p60-t9-et-t9gt-sondage-avez-vous-des-problemes-de-coupures-remise-gaz https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.youtube.com/watch%3Fv%3DgCrFb986MVU&ved=2ahUKEwjv8Ofv9_f0AhVaQ_EDHQTBDuoQwqsBegQIBBAF&usg=AOvVaw3-obkZ2_R6T41aPOIr42Xp Same issues!!!

Although i am not a mechanic (and the motorcycle is brand new with around 800 km on speedometer), in my eyes issue like a software one..... I might be totally wrong but this is the "way" that issue came up: Around 200km on the speedometer. Excellent performance with no issue from her. I needed to disconnect the battery. After this disconnection, issue came up. Every day for at least two times per day while using quick-shifter for downshift in low rpm (NOT LOWER THAN 2200 rpm but close to 2500 - 3300). This hold for around 100 - 150 km. When issue came up I had no throttle and the check engine light up with error code P0638 I thought to make a reset via menu & in addition to switch off and switch on the quick-shifter via menu also. I took this action in order to make sure that after battery disconnection ECU "understand" the actual status of quick-shifter. Stupid or not this is what i did just in case. From my understanding this should not be the case but you never know. Up to this date i have another 400km with no issue at all. Tested with gear changes w/o QS, w/ QS, down shift & upshift, in any rpm. It might be just a matter of lack or the issue might come up again. All the above might be totally irrelevant with the problem. I really do not know. But, I am almost confident that has nothing to do with real hardware failure. Sounds tome like sw error. Keep you updated .

Hi all, I am previous owner of a Tracer 2017 and an actual owner of a Tracer 9 GT with 300km on the speedometer located in Greece. Unfortunately I faced already the issue you described above. Trying to find out why, I discovered that it took place when I used downshift with quick shifter, at least this is my feeling. And although I am not sure, I think in low rpm. I think around 2500. I saw also that issue has been reported in France in Tracer 9 GT and MT09SP. Has it been solved for you?
