Be afraid? Yes, I would be afraid to buy that bike. Just another cosmetic fix-up. Certainly not a restoration.
What does "engine and frame detailed" mean? It means rattle can paint job to make it look good on ebay to buyers thousands of miles away. No mention of important items like the bearings, seals, piston, what bore it is on, connecting rod, trans gears, etc. If you can't see the parts, they don't matter on fleabay.
