I am using Vespa P 150 x.It has a is 150 cc engine. The fuel average is not too much good.Some one told me that for batter fuel millage there is a option that I may change my original Vespa carburetor with the 70 cc motorcycle carburetor.The average mileage of that 70 cc motorcycle is 50 km per liter.
Technically if i change my Vespa 150 cc carburetor with 70 cc carburetor it will affect my ring piston/engine ? If no , what other aspects should i also see to change while using a 70 cc carburetor in P 150 x Vespa.
Need your kind technical opinion about it.
