That pin is supposed to be protruding from the sprocket. It is pushed inward by the cam in the clutch actuator cover. If you rear wheel locked up, that pin is not the problem. Is the chain still on? Is it the proper tension? A loose chain can bind inside the clutch actuator cover where it wraps over the drive sprocket. Is the clutch cable adjusted correctly? Possibly the cable stop, the small brass part that clamps onto the end of the clutch cable has slipped allowing the clutch to remain engaged. Check these things and get back to us.

no chain is on and tight i havent had a chain tensener on in a while now when i try and engage the engine there is no compression and the sproket on the engine just freespins
 
look in the right side of the engine at the clutch parts under the clutch cover and see if they turn when you try to start the motor with the clutch in start position
 
Yea either your cable thing moved OR your clutch pads wore down.

Either way, just loosen the cable on that arm a little.
 
Is the engine actually turning over or just the chain going around? Sounds like you may have the clutch cable too tight. If you pull the clutch cover can you still spin the rear wheel freely?
