    Very interesting about cam, that when I bought I ordered normal ( no mod ) RR4224 cam from PPG. He sent me cam but with PPG superlight mod ( BUT I never not tell to him and he not asked me about need or not a superlight mod ? ) . So was in cam drilled out 1/2" inside. YOu see in pics. Last year I not us too much because I was problem with rocker arms crack and cam damaged in middle little bit. Really bit !!! I think I have time and have other cam I sent to WEB CAMSHAFT to repair. After this I install back and us aprox 1,5 hour and result ...in pics. So Guys if do you buy somethings from your Rotax dealer ask him many times sure he have parts what do you want. Example : IF you like buy 300hp engine dealer not send you 10ps 30hp engines....
