Just looking for simple opinions. Just browsing for cheap 125's on Craigslist (a common occurrence when I'm bored) and stumbled upon an 03 kx for $600, ad says it has a siezed top end. Haven't contacted the seller, and obviously it could be a whole can of worms beyond a top end rebuild. Could just be as simple as a new piston/rings and for safety a new cylinder (or at least sleeved?). For the price and how cheap it could potentially be to fix, sort of seeks like a no brainer. Worth it? Or pass? Have the skills/abilities to do the work myself obviously.
