Thanks for the link to the sight. Turns out there are still kits and stuff available for my moped (variant america). Unfortunately they are a little expensive and probably illegal here in the states. Seeing as how there are no dealers listed for the U.S. and all the prices are listed in Ptas or Euros.
Some of the mods seem pretty straightforward like the crazy muffler and the larger piston and cylinder. but where do the "rollers" "nozzles" and "reeds" go or do? and what is the difference between a "mahle Piston", an "asso piston" and a regular old stock piston? Just trying to figure out what makes these mods work. Thank you for your help.
