Don’t forget that with every 2-stroke cylinder kit upgrade, it may be necessary to put a tablespoon or so of two stroke oil in your gas tank with every fill up. 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 when putting a larger cylinder on your scooter, to up-jet your carburetor. We recommend starting your jetting rich and then working your way down to the perfect mix.
