[QUOTE="ron82, post: 1379237, member: 118391"] [b]Yeah Fix it[/b] If you dont have any mechanical skills then you have a nice bike to start learning. A 85 cr250 dont have no powervalve and its older so you can find all kinds of info on how to repair different things on that bike and you can also find a lot of good deals on parts on e-bay and craigslist as long as you are sure its the right part. Check out some videos on you-tube, There is a lot of videos on there showing how to work on your bike and might give you a better idea of what your dealing with. I have the same bike, i got it for free because it siezed up on the previous owner so he took it apart, didn't know what to do and left it uncovered in the rain and weather for five years. I took it home and removed the engine, I measured the cylinder and it showed that it had never been bored(66mm) so i searched e bay for a piston .050 for my year and i found a wiseco piston and rings for $50. I also found a 89 cr250 bottom end with everything including a good crank and excluding the clutch cover for $50 plus $20 shipping. The bottom end even came with gaskets stator covers and other extra parts. I got a good deal on that because the right side crank seal blew out so i ordered an engine oil seal kit for $22 and a gasket kit on E-bay for $20 Crank bearings For $30 and about $60 for trans bearings From local bearing dealer. I watched videos on how to remove and install crankcase bearings on you tube, It looked easy, i just had to make the tool to split the case and remove the crankshaft, with a little welding it was simple. The pic at the bottom was the 85crankcase of my bike when i got it. the engine on my bike in the other pic is the 89 i got off e-bay totally compatible after swapping powervalve actuator rod and dowel(for height) and using 85 clutch cover. So in the end i put about $250 into a free bike the engine is now totally rebuilt and runs strong. It was pretty easy and now i got a cheap bike that rips. So I'd say get some tools and a book on your model and just learn what you can about how it works and how to work on it. The manual will teach you a lot if your serious about it. Then you wont have to pay that much for spark plugs and idle screws, just for the part. search microfiche for your model, you can get part #'s and find detailed pictures on everything for your bike incase you forget where something went And like others have said, it will be a lot cheaper and more fun and you will be a better troubleshooter if you bring it to life yourself. Good luck with it and i hope this helps! [/QUOTE]
