Wet Clutch- check and change oil and verify that you have a properly rated wet clutch oil in it. Do NOT use the Chinese shoes to rebuild it. Replace the whole unit and check sprag bearing closely. You do not say how many miles but safer to replace it too. While you are working on wet clutch, add the brass clutch weights for better riding performance and clutch engagement and wear.
