CHECK YOUR AIR FILTER AND REPLACE IT WITH AN ITALIAN ONE, I FOUND THAT THE STANDARD FILTER WAS TOO RESTRICTED FOR THE ENGLISH CLIMATE, I REPLACED IT WITH AN ITALIAN ONE AND NOW MY SCOOTER RUNS PROPERLY, IT MADE A 3 BHP DIFFERENCE ON THE DYNO. YOU SHOULD ALSO CHECK YOUR CARBRETTER JETS AS THEY ARE ALSO RESTRICTED.
