the small cog in the engine broken
My bike is now as if the clutch isnt even making contact(but the clutch is working fine).
The problem is that the small cog(where the giant slot screw is and next to the big clutch cog) now cannot mechanically connect to the engine crankshaft.
All i want to know is, how is this thing normally supposed to mechanically connect to the crankshaft?
Is there a 'slot' in the axle hole of the cog that slows it to drive the crankshaft? (in my engine there is a slot in the cog but no 'pertrusion' from the crankshaft to meet this slot)
edit: I also discovered a 'slot' in the crankshaft, if that helps.

Thanks for your reply.
We fabricated our own peice of metal from a bench grinder.
I find it improbable that the metal would snap under the forces. The bike was also slowly slipping more and more until it couldnt move me.
More likely the metal wasnt installed in the first place(if it snapped the characteristic imo would be catastrophic failure instead) and was relying on the press fit of the cog on the shaft.

i see you posted that you fixed it & i was wondering if you ever found out what actually happened? did you find any evidence of the missing/broken key?
