CY100 PE28 Sintered Manifold


Fits a Keihin PE28 onto a CY with XR100 engine

Available on backorder

SKU CY100PE28 Categories ,


This manifold was designed to fit the 99cc long stroke engine in a CY frame. This is the engine of a XR100 / NSF 100 or XL100S. These engines can be fitted with bore kits up 125 or even 145cc, and will require a big carburator.

There are no ready-made manifolds on the market that will fit any big carburator on a CY, and this one was especially designed for the Keihin PE28.
This Manifold will fit a Keihin PE28 of PWK21 plug&play. Take note that the sidecap will not fit!

This part comes with mounting bolts, packing not included.

In order to install the carburator, you need a rubber connector. This part was designed for use with ShiftUp part no. 201083-GP
