All issues starts after I decided to set up a new air filter and to clean the trottle valve and body. So, after that my bike starts working really unstable. My friend said that I have to "adjust" the throttle after the cleaning. But I don't know how.
I've found only "Zeroing the throttle" paragraph in "Gilera_Fuoco Workshop Manual". But there is a warning in the end of that paragraph: "THE TPS RESETTING POSITION MUST NOT BE CARRIED OUT WITH A USED THROTTLE BODY..."
So, I am still using the same throttle body. That means that I shouldn't do one, am I right?
Any suggestions where can be the problem?
