Description

Here is our NCY air cooled 70cc cylinder kit for 50cc 1PE40QMB Minarelli Yamaha Jog Style scooter engines.
NCY Cylinder with Head (Ceramic, 68cc, 47 mm, 10 mm Pin, AC).
If you are a racer, or you see yourself as a racer when you look in the mirror in the morning, then this Ceramic 47mm bolt on Minarelli based cylinder kit is just what the doctor ordered. This NCY big bore kit has some of the most aggressive porting we’ve ever seen. Don’t forget that with every 2-stroke cylinder kit upgrade, it??s 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. In this case, we suggest using Ipone 2 Stroke Racing Oil because of the kit’s aggressive nature. 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. This kit will only work on scooters with a 10 mm Wrist
The AC Ceramic Plated Aluminum Cylinder Kit includes:
47 mm bore (68cc with stock stroke)
5 transfer ports
10 mm or 12 mm wrist pin (your choice)
Single compression ring
Bridged exhaust port
