intake Manifold for Malossi 70 cc cylinder

Hi

I have a yamaha aerox 50cc scooter with a Malossi 70 cc cylinder kit installed M# 318284. The after market rubber intake manifold has a leak and I can't seem to find a replacement manifold to fit the cylinder. Since I moved to the USA I can't get parts for the Aerox scooter. Do you know where I could find this manifold either on an internet parts supply or at a retail scooter parts store outside the USA.

Thanks Much

Bruce
