I too own a 2001 people 50 . I bought it used but I have been told that in 2001 the people 50 was imported without restrictions other than the cdi , which restricts revs to keep you from damaging or blowing up your engine . My people will go past the 80 kph on the speedo . My gps indicates about 45 mph . I have replaced the drive belt , clutch weights , roller weights , air filter element , and the spark plug with an iridium NGK BPR8HIX (ordered through Advance Auto). I also run 93 octane premium without ethanol and amsoil Interceptor 2T oil . Make sure you are running 25-26 PSI in front and 28 PSI in the rear tire . Hope this helps , good luck .
