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 Mikuni VM26. This is a highly desirable carburator but also quite tricky to fit between the engine, the frame, the gasoline tank and the exhaust pipe. A down-under exhaust pipe is therefore recommended.
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. 201081-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
– Warranty disclaimer –
- Alumide is claims a heat resistance of up to 140 degrees Celsius.
- This is borderline for the purpose of an intake manifold. Some pieces last long, other don’t.
- Consider this a prototype for testing purposes. No warranty can be given about heat deformation.
For a solution that will hold up over time, a CNC part in solid aluminum is recommended.
