MALOSSI intake pipe gasket for MBK / AV7 motobecane

Intake pipe gasket for MOTOBECANE AV7 engine? Big exit, well suited to racing pipes with big exits. However, this seal is 0.50mm thin. Unlike the origins and CGNs, they do not form the thermal barrier between the cylinder and the pipe. The heat from the cylinder is therefore transmitted more to the pipe and to the carburetor! It is not a drama in itself, but a seal of 2.5 to 3mm thick would have been in our eyes preferable.
