One of the few functional complaints about my ´95 RF900 is that the fuel petcock is so hard to turn that it´s dangerous to try and turn it while riding. My Suzuki dealer has not seen enough RFs to know whether they are all this way, or I have a bad one. What is our collective experience with this part - are they all extremely stiff, or do I just have a bad one? Thanks. My bike has 41K miles and feels like nearly new. Works great on Avon Storms.
