I know this question must come every couple of weeks. Thanks for your patience. I'm looking to get a used WR450. I see a lot of '06 - '08 in the $3.2k +/- range. I found a '03 for $2k. Claims to be well maintained, used mostly for trails and to have roughly 200 hrs. I've asked to have a mechanic check it out and give a written report. My concern is the engine. What are the odds that I'm going to be putting money into the engine in the next 12 months? Also, any other issues to watch out for.
