I'm looking get get some perspective from others... First off, thank you to all of you who have been providing me with help over the past week. I burned up the piston and cylinder on my 2006 YZ250F. Right now I'm looking at a top end kit, cylinder replacement, and a valve job. When I add all of this up, I don't know if it makes sense to put that kind of money into this bike. I paid $2,200 for it back in 2009. It's a low hour, very clean 250F. If my valves are bad, it looks like that repair alone would probably around $700. You add the top end kit and the new cylinder, and we are looking at over $1,000. I don't race, and I don't need the latest and greatest. I just need a bike to ride to spend time with my boys. The thought of sticking $1,000 plus into it isn't real exciting. What I'm wondering is if anyone can give me perspective on how much I may be able to recover if I parted the bike out? Is this a feasable option, or am I just wasting my time? I looked at pricing for components on Ebay, and if I could get in the ballpark of what those parts are going for, I could recover a good amount of $. Has anyone actually done this and come out ok? Is there a decent market for the parts?
