This sort of raises the whole anger of buying bikes off ebay. The tell tale wet look to disguise the condition of the bike. Over the years I have learnt to ask the right questions but you still get surprises when the bike finally arrives, no matter how thourough I am.
I brought a PE400 on ebay a few years ago. I watched the questions from potential biggers and read the description, but nowhere had the seller indicated if the bike ran. After I asked that, the seller indicated there was no piston in the engine.
Another bike I brought last year, a YZ465, looked great from the photos but when I received it, one of the crankcases at the front had been severely damaged and welded back up. The generally condition of the bike was very poor and required a complete rebuild. Chopped out wheel bearings, swingarm bearings you name it. Even the barrel had been damaged badly at some point and rewelded. None of that was disclosed by the seller.
Maybe next time I'll ask a forum member in the area to check a bike out for me. Seems to me we have a big family able to do that.
