Good evening friends, I want to consult my engine tune-up problem, I can't get a stable idle, there are ups and downs in the RPM and it ends up turning off, after riding for half an hour and with the engine relatively warm stop failing. It is noticeable with less reaction when operating the accelerator, it works like drowning, you hear back-explosions and it wants to stop, you notice a heavy operation, it is difficult to pick up speed, it takes time to reach 100 km / h. I have regulated the TPS voltage at 0.58 V and touched the air screw a bit. I have to do the work because in my city there is no suitable workshop for this setting. I wonder how the ECU is resetting, what sensor or what else may be failing. Should I check the throttle cable adjustment? Is the TPS sensor damaged? or the MAP? I'm really tired and thinking of selling it, because my experience with this bike was not good from day one. I think the problem is in the air and fuel proportions of the mixture (the spark plug is a bit carbonized), but I do not know the procedure to achieve the correct setting. In advance, I greatly appreciate any help that can end this problem.
