This is our high quality 70cc cylinder kit for 1PE40QMB Minarelli Yamaha Jog Style scooter engines from NCY. The NCY 47mm cast iron liquid cooled Jog/Minarelli 2-stroke cylinder with head is a simple bolt on 72 cc kit for Minarelli, liquid cooled, 2-stroke scooters with a 12mm wrist pin.
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.
The kit includes:
LC iron cylinder
47 mm bore
5 transfer ports
12 mm wrist pin
Single compression ring
Bridged exhaust port
