Find Boosted306, Sam here and get a 49cc ported piston port cylinder w, a new set of rings for $60. Then leave the base gasket off and glue it down w/ Yamabond or Hondabond, that will increase the compression. Then get a Walbro WT-813 and alum Zenoah intake and mod it to fit, then get a Fatty X7 exhaust. That setup will make a real difference in power.
