Hard to fix a bike on the internet. Luckily the Pro motor lubes the mains by the transmission oil. The rod can be checked for vertical movement, Should be no up and down play. They always have play sideways. The crank should spin freely, but you are turning the flywheel and clutch basket. It really should have the lower end flushed out. If you go any farther the engine can be removed without removing the skid plate. Good luck.
