I have all of a suden gotten a rattle coming from the clutch lever, It doesnt start until about 6000rpm, I can put my hand over the top were you adjust the lever and make it stop, I have tighten the flat head screw with the nut of the bottom, but that didnt help. I also check all the other botl and nuts in that area, still when I grab hold of at the pivot point it will stop. Any ideas?? Help its driving me crazy!!!!
