1985 KX500 Engine. This is the only year that the KX500 was liquid cooled with no power valve. You can still get parts for it, I have included two complete gasket kits, oil seal kit, and the clutch friction plates. I got this engine to refurbish it but have since moved on to another project. Everything is mostly here, rod looks to be in good condition. The right crankcase cover (clutch) is broken but you can still find them on eBay. The cylinder will need to be replated/sleeved. If you have any further questions please let me know. Text is best.
