I just bought a used 2005 CR250R. Got it for $1,400. I have been checking it out to see what it needs. So far, I replaced the sprocket, rear tire, side plastics, and grips. I still need to get a new chain, repack the silencer, get the fork seals replaced, and check out the engine. Engine starts right up, and doesn't seem to smoke much. It sounds quiet, and revs good. This is my first 250 2-smoker, so I am not sure how it is supposed to run. I have nothing to compare it to. I've been spending most of the time just trying to clean it up, and replace what needs to be replaced. So far, just routine maintenance stuff. After that, I will check out the engine real good. I will probably do a new piston, just because I think it needs it. Previous owner didn't do any work on the bike. It's all original. No idea how much run-time on this bike. Previous owner claimed "low hours", but they ALL claim that. Bike was pretty clean, and the price was right, so I went for it. I hope it won't be a "money-pit". So far, I spent a few hundred on parts. Still gotta do them fork seals though. My last bike was a 2000 CR500R, which I had to sell back in 2004 because I needed money. I always had plans to get another bike someday, and that day is here!
