A simple bolt on 72 cc kit for minarelli based, air cooled, 2-stroke scooters with a 10mm wrist pin. Don't forget that with every 2-stroke cylinder kit upgrade, it�s necessary to either supplement the stock oil injection system with about a tablespoon of two stroke oil in your gas tank every fill up or eliminate the injection syetem and pre-mix. We recommend Ipone oils for all of NCY's big bore kits. Both 1400-1005, City Oil 2 and OIL-IPCITY, Scoot City Strawberry Synthetic are great options.
Also, don't forget to upjet your carburetor. We recommend starting your jetting rich and then working your way down to the perfect mix.
