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

Material & Finish

This part is made from laser-sintered Alumide, a mixture of aluminium and polyamide.

  • heat resistant up to 140 degrees
  • looks like sand-casted aluminium
  • Alumide has good thermic insulating capacities
  • the mounting flanges are sanded to ensure a well-sealing finish
    sealed with matte, fuel resistant clear coat

– Update about the longevity of this product –

Although some users have traveled 1000’s of KM using this manifold without any issues, others have been reporting deformations of their manifold over time.

The conclusion is that the Alumide is pushed to the edge of its heat resisitance when used as a manifold, and may not be sufficient for long-term use. This is especially the case on modified engines and big-bore that produce more heat.

Therefore, if you’re looking for a manifold that will last forever, I recommend spending a little more on a CNC aluminium part.

I will continue to look for improved materials to make these arts available to the CY community at a reasonable price. In the meanwhile, please consider this an experimental product, suitable for test-cases only.
