NCY 47mm Nikasil Air Cooled Jog/Minarelli 2-stroke Cylinder with Head.
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 upjet 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 10mm Wrist
