I just bought a 92' CR500 on tuesday off a pre owned dealer. The bike started up fine and ran fine when the dealer showed it to me. However when he did start it he had to stand up on a milk crate to kick start it. But when he did it started and ran great. When I got it home it would not start at all I tried standing on a chair to get leverage. I went through three plugs already. It sounds like it wants to start it pops every now and then. And sometimes smoke comes out. But it just will not kick over. Any sugestions would be greatly appreciated. I just bought this thing and have not been able to ride it yet and its killing me. :bang:
