Intake manifold POLINI 19/24mm for Derbi D50B0, EBE, EBS

Polini intake manifold for geared mopeds with Derbi D50B0, EBE or EBS engines. Due to thermal loads, it is not uncommon for the intake manifold to develop cracks and become porous. Then it is time to replace this component. Tears cause the fuel-air mixture to become too lean. Therefore, combustion temperatures are too high, and the engine runs roughly and loses power. This could lead to serious engine damage. Carburetor connection: 24mm Intake: 19mm
