Hello all, I’ve been having problems with my Piaggio x9 125 for a few days. She got a new Keihin carburetor and turns you on the main stand up to almost 11,000 tours but who you drive yourself turns you max. 8.500 more is not possible. Speak about 80-85km/h. I’ve read this before but nobody of the whole people once wrote his final solution or what the problem was. Maybe there’s someone here who can help me any further. Is from the year 2002 the X9. And has just run almost. 20,000. Dear greetings.
