Boy, did E-Bay piss me off, I was looking for a rear disk for my 1982 ing. I saw one on E-Bay for a low bid , the ad said, it would fit the 1100 so I sent him a e-mail to make sure it was the right one, he said yes, so I won the bid. When I received the disk, it was the wrong one, the one he sent had 4 holes, mine has 5, so I told the guy Wabout the problem, he said send it back for a refund. The problem here is: he said I have to pay for the return shipping to get my refund. I contacted E-Bay about this problem, and they said, yes, I have to pay the shipping to get my refund. What kind of a stupid policy is that, I have to pay to get my money back for his mistake, boy was I pissed. I decided to keep it and try to sell it here, the trouble is, I don't know from which bike it's from and the seller doesn't seem to know, what an idiot. Boy, did I get screwed. Now I have to figure out where the disk is from.
