Any problems with used bike sitting for long?

And a can of SeaFoam.

Doh! I knew I was forgetting something ... and oil and a filter and I'm sure there's more.

My bike sat for two years before I bought it with no problems at all. Just follow all the steps these guys said, and you should have no problems. I would definitely change the oil, but I tend to be very nervous about oil anyways, so it's up to you.
