You don't need a new sheave to do greaseless rollers/sliders.
Your spot on. It's normal to hear noises from the clutch with a greaseless setup. Actually, some make noises even with the grease.Thanks guys. I went ahead with it and I ended up servicing everything while I was in there. Everything works well after putting it back together, got a little more torque out of the deal.
One other question, there is just a slight knocking coming from the primary clutch now. Idles just fine with no knocking, and once the clutch engages there is no knocking, but that split second between idling and the clutch engaging there is a touch of knocking, which I'm assuming is because of the new greaseless rollers (Dr. Pulleys square-ish type) not having any grease to silence them when they move outwards. Is this right or should I be a little worried??
