[QUOTE="reepicheep, post: 1390932, member: 104942"] My KDX rebuild was the first bottom end I ever did, and it went fine. A good learning experience. You will have to spend some time thinking about various steps and doing some research, but ultimately it goes pretty well. Hint... you will need a deep freezer and a BBQ grill for reassembly. I'm serious. I wouldn't re-use that crank, and that cylinder is going to need to be replaced or sleeved... perhaps it could be bored out and plated. The pry marks on the case aren't a problem, though it does indicate that a previous repair was somebody who was inexperienced and frustrated. Hopefully they gave up before actually getting the case split and sold it to you or took it to a shop, so the scope of their damage is limited. If you do rebuild it, you will be either paying stupid high prices to Kawasaki, or running around to your local bearing shop for bearings and seals (with the occasional unobtanium part order from Team Green). You will also be running back and forth to Harbor Freight for some new tools like steering wheel pullers and bearing splitters, and various odd long bolts to cobble them together into something that will roughly duplicate the "real tools" for the job. It's all very doable, but time will tick by and you will spend a lot of time working on it. That's probably the argument for just sourcing another engine. If you can find something on ebay that maybe just needs a top end rebuild that you could buy for $300 or $400, you might not be out much more money and will save yourself a BUNCH of time, and you can keep the old bottom end for parts for future adventures... On the other hand, there is no promise that ebay motor is any less likely to blow up then the one you just crinked. Kind of a "roll the dice and take your chances" kind of deal. Either way it's totally solvable. Just make sure you like the bike, as you will be into it for some decent money before you are done. If it's the bike you want (it was for me) it's a bargain. If it's not the bike you want, sell it to somebody else cheap and let them restore it and go buy one of the smoking good deals on other dirt bikes out there right now. [/QUOTE]
