This Chinese company sells a camshaft that has wrong design compared to the Piaggio original. It has fewer lubrication holes and in wrong places. I contacted them when I received the camshafts and according to Piaggio representative service, indicating that they would work but due to the improper lubrication the engine would develop serious problems later on. The seller does not accept to correct the products or to refund. The seller also keep on selling the camshafts knowing the difference. I am attaching photos showing the difference.
