Moped Army

OK... I have a tomos lx 2003 and i have a crap load of stuff on it....shaved manifold, 70cc, biturbo, carb, intake, airfilter, sproket, and I have done a little tweaking. My moped can hit 50 and hit the pin with a slight incline. Now i was talkin to this kid from moped army and he was sayin he weighs 150, 20lbs less than me only has the biturbo and 70cc and he has hit 70mph. When I heard this I said wtf a tomos cant handle that speed yet he swears by it. Now is it just me or is this a bunch of BS. RESPOND WITH WHAT YOU GOT AND WHAT UR TOP SPEED ON FLAT IS!!!!
