The engine number will not give you what you need. The VIN is the key. You will find the VIN number stamped into the center steering stem that the forks attach to. Call a Yamaha dealer with the VIN and they can tell you what year and model of bike you have.

A “very helpful” rating for this answer? Thanks!

The engine will need a complete overhaul. New bearings throughout, new piston, rings, water pump and a full set of seals. A cylinder bore job or new cylinder also. You are probably looking at $2000 to $2500 for the repairs. A used engine may be a lower cost choice. Google motorcycle salvage yamaha and see what you can find.
