I purchased a motor from eBay with 300 miles on it. Yes 300. Basically brand new and had been sitting for years. I dropped the oil screen and everything looks fresh. I'm going to clean and freshen everything on the bike before I put it back together.
I recently bought a 2004 Ninja 250 as a commuter bike and also to put some serious miles on. I'm looking forward to ease of maintenance, going slow, and fingers crossed for 70 mpg. Should be a good fall riding season.
