Liquid Cooled 72cc Cylinder Kit for 50cc 1PE40QMB Minarelli Yamaha Jog Style Scooter Engines

This is the NCY-made liquid cooled 72cc cylinder kit for 50cc 1PE40QMB Minarelli Yamaha Jog Style scooter engines, a simple bolt on 72 cc kit for Minarelli, liquid 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 2-stroke oil in your gas tank every fill up, or to eliminate the injection system and premix. We recommend Ipone oils for all 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.

NOTE: This kit will not work on the Kymco Super 9.

This LC Cast Iron Cylinder kit includes:
47 mm Bore (68cc With Stock Stroke)
5 Transfer Ports
10 mm Wrist Pin
Single Compression Ring
Bridged Exhaust Port
