(As I understand) Engines put out and electrical charge or RF that causes the rubber to break down and crack and pit. Like an EMF, but I was told it was RF. It is the main cause for aging of rubber lines... Also the closed compartment contributes to this. For instance my streetbike doesn't get this effect.This is why they get so faded. Either way I was wondering if anyone did Samco line in there vx's....Originally posted by tomcat837
