I found a great deal on this Yamaha TTR125 on Facebook Marketplace. The bike is pretty new and looks complete, but the engine is a total mess. Someone else already took the top end apart and decided to sell it when they saw the extent of the damage. Last week we took the engine the rest of the way apart. Along the way discovered some additional damage, but nothing major. After ordering the parts, I did discover a major problem. Nothing that cannot be fixed, but its going cost me $$$$.
