kay. im shure if youve read some of my other posts you know about my p.o.s. 94kx125.
if not long story short -ran good when bought, 2months later the engine all fell appart at once.
im looking for a replacement engine cus everything on the frame is in great shape and worth plenty of $. i found this on craigslist but not to shure if it would be a pain in the azz to fix or not, how expensive it would be or if the things like the carb and swingarm bearings would be interchangeable. any help would be appericeated.

i also have a 81' kx250 lined up that runs but has no pipe or header. would the engine mounts fit on my frame?
