POLINI D.17/19 PEUGEOT Reed Valve Intake Manifold

The POLINI D.17/19 reed valve intake manifold is designed to optimize the performance of the engines of MBK and Peugeot motorcycles. Its installation requires the removal of the existing manifold and the fixing studs, ensuring that the gaskets and rubber rings are correctly positioned.

For MBK models, it is recommended to use a piston with a diameter of Ø46 in combination with a Polini exhaust, with an optimal carburetion that includes an original main jet of 78-76, and for SHA 15-15 and PHBG 19 AD carburetors, the recommended main jets are 68-70 and 82-84, respectively.

For Peugeot models, it is necessary to detach the engine from the frame and follow the same precautions for the gasket housing. It is recommended to file the two edges by about 4 mm before reassembly. The ideal carburetion for Ø40.4 and Ø46 pistons includes an original main jet of 66-68 for both models, with jets for SHA 15-15 and PHBG 19 AD being 68 and 88, respectively.

To improve power delivery at low revs, it is advisable to modify the variator tuning by changing the weight of the centrifugal masses. This manifold represents a strategic choice for those looking to maximize their engine's performance.
