Welcome to the site! Fun is never cheap!! Personally I think OEM Cranks are the way to go. Kawasaki makes a d**n tuff crank spend a few more bucks get it balanced and you wwon't be ddisappointed. I have a 94 And just got its first top to bottom freshening up and the whole bottom end and tranny was all in spec! All new bearings and sealsand piston and rings and she was all good. With good routine mmaintenance kx500 are very dependable!! Now go get it and post some pics

I would rebuild the crank with a Wossner rod kit, have it welded, balanced, and trued.
Cheaper then OEM and really tough...

Yea I know it aint cheap ive got a 00cr250 I just rebuilt ground up (engine wise) last winter. I want the bike for a mini buggy ive got. Kinroad 250...its my uncle but he hasnt ridden in over a year. Prob pull the engine and sell the rest of the bike...
As for rebuilding the crank how do I do tht. And do I have it rebuilt and then welded and trued? Also Would I just need complete bearing and seals kit and get the rod to complete the bottom end? I just dont want to buy the engine just to not be able to afford to rebuild it when needed. How long do these engines last. Somone told me they blow through cranks because the bore is too big...any opinions advice facts are welcome. Thank you guys

Welcome to the site Rougedante....
providing you keep on top of your general maintenance and always run quality 2 stroke oil, you should get a few years between rebuilds with ease. One of the old gurus on here claims he got 11 years out his original motor before taking it apart for the 1st time.
"EDIT"...I was wrong...it was 12 years... :mrgreen:
