I am having trouble removing the gear that holds the clutch pads. I can't pull it out with my hands. I am scared to try to pry it out. What is the best way to get it out if it doesn't pop right out?Are there any marks inside the cover, also check the other side where the chain connects to the bike. I had a kit where the engine sprocket and clutch shaft wasn't machined right and the chain rubbed on the case.
