This high quality accessory is the liquid cooled 72cc cylinder head for 50cc 1PE40QMB Minarelli Yamaha Jog Style Engines from NCY.
The NCY 47 mm ceramic liquid cooled Jog/Minarelli 2-stroke cylinder with head is a simple bolt on ceramic 70 cc kit for Minarelli based, liquid cooled, 2-stroke scooters with a 12mm wrist pin. The kit will let a scooter run at high RPMs regularly. The ceramic coat allows for the engine to run a much higher RPM than normal.
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.
