CY100 Sintered Manifold For PE22-24


Fits a Keihin PE24 onto a CY with 100CC engine

Available on backorder

SKU CY10024PE Categories ,


This Manifold was especially designed for the Keihin PE22 and PE24 Carbs, paired to the standard 99cc long stroke engine, which can be bored up to 115 or more CCM. This intake channel is 24 mm at the carburator and at the the cylinder head, ensuring an optimal fit to the XR100 head.

Ideal to spice up your engine or complete your bore-up project. No need to mess around boring up your 40 year old original Honda manifold, which will only allow you to go up to 16mm.

This part comes with mounting bolts, packing not included.

Make sure you get the matching rubber connector: Shiftup Part no  201082-GP.

I have designed a special matching chokelever that can be operated from the left hand side. Have a look in the shop. (Not compatible with replica carburators)

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.
