| 44mm sleeper head kits if any of you guys are after extra power / torque and rpms from your engine and want to stay with the single piece barrel design, i have a couple of complete brand new custon kits for sale. the cylinder is tripple boost ported, exhaust port is hand ported to maximum specs, the piston is tripple windowed and lightened, the rings are shaved, pin / bearing and plug are included. the power difference between the stock 49cc and this custom 49cc is well worth the $70 asked. yes only $70 also if your not 100% satisfied with the performance gains from this kit, i will refund your money with no questions asked, valid for 1 month, howszat.
