intake manifold Polini 19/24mm for Derbi D50B0, EBE, EBS

Inlet manifold from Polini for geared mopeds with Derbi D50B0, EBE or EBS engines. Due to the thermal loads it not uncommon for the intake manifold to develop cracks and become porous. Then it is time to replace this component. Tears lead to leaning out of the fuel-air the mixture. Therefore the combustion temperatures are too high and the motor runs rough and loses power. This could lead to serious engine damage. Connection carburetor: 24mm Inlet: 19mm
