Puch Metrakit 43.5mm "65cc" Big Fin Cylinder Kit h20 3 step bellVintage, long discontinued, and new old stock Metrakit for Puch! Rarely seen 65cc big fin kit. Case iron bore with a 2 ring piston should offer a long and reliable life. The large cooling fins on the cylinder and head will shed heat easily. Angled exhaust port measures 26mm at the exit. Intake measures 21mm at the opening. This is an older cylinder kit. That means it isn't as shiny as a brand new kit. It also means the mating surfaces are still nice
