I recently bought a KTM Duke 200(2022, 1561 miles) from Facebook with $4400 and the second day I bought it it wasn't starting and I towed it to the dealership and he spend almost a week and said "Found that the exhaust valves snapped the ends off and damaged piston, cylinder, head and spark plug. We will need to perform a crank up rebuild to correct." and he said the KTM will decline the warranty and you need to pay us $3600 for this repairs.
I don't know what to do, please give me a suggestion. I'm totally fucked up!
