I've been slowly gathering the parts to replace the clutch on my 07 k12gt. The bike has a little over 41,000 miles and I'm starting to feel a slight grinding through the clutch lever, but it's not slipping yet. I figured I would just replace the clutch pack to be safe. So far I've ordered: A barnett racing clutch pack, all of the screws to put the clutch cover back on, the clutch cover gasket and a thin walled 30mm socket. I've seen some people use that big wrench that fits around the clutch basket to keep it in place while removing that 30mm nut in in the center of the basket. Do I really need this tool, or are there other ways around it. I'm also going to order the stopper that goes into the crankshaft position sensor hole. I am going to install the timing chain jump guide as well. I'm trying to "bulletproof" my bike.
