Default Re: 49cc vs. 66/80cc True or False?

it's that 'all things being equal' part that gets you in trouble sometimes - not sure by how much, but 49cc piston is WAY lighter than 66cc - thinking it takes maybe a 1/4hp just to throw it up & down at 6000rpm - this may be why 49cc gets higher rpms on flat ground
Sometimes I sets and thinks, sometimes I jes sets.
