CY50 20mm Sintered Manifold


Fits a Keihin PC onto a CY50 with standard engine or big-bore kit


SKU CY5020SLS-1 Categories ,


This manifold is designed to fit the standard 49cc short stroke engine. 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 in 20mm or 22mm intake diameter. The position of the carburator is a perfect copy of the original. Ideal to get the best out of your bore-up project.

This part comes with mounting bolts, packing not included.

Material & finish

This part is built to last forever: CNC milled from corrosion resistant billet aluminium 6082, glass-bead blasted for a smooth finish. I keep only a low stock of these parts, because they are very expensive to make. When out of stock, delivery will take up to 5 weeks.
