The problem was a missing pilot screw in the right carb. I had a guy who adjusted the carbs and he probably turned out the screws too many times. Now I have new "d" shaped pilot screws and the bike runs ok. Thanks for any suggestions in this matter

I can see by the security bits that he probably tried to turn out the TPS sensor. I am trying to determine what is the role of the TPS on our bikes. The manual says not to remove it, if so, can it damage the sensor? Has anybody ever removed the TPS? I am so glad the bike finally runs strong. Best regards.
