I went and replaced all my bushings in the primary clutch. bought the right bushing tool to remove and put these in. when I went to put it back together the spider seemed like it didn't want to go back on. it was hard to push down through the bushing in the movable sheave. I put Yamaha part # "s back in. do they need to be worn alittle to move easier or is this the way there suppose to be.do I need to maybe increase the relief cut? thanks for any help in advance
