and i am in noway trying to be smart but when I just Googled scooters it showed lots of bikes with 2wheels and also 2wheels at front and one at rear and also "scooters " with 2 rear wheels and one front so as my motorcycle uses a scooter engine then can i not ask a genuine question question regarding scooter engines as thats what engine it is and id like to keep it ?
