I have a 2004 YZ85 2-stroke,

 couple years back i was riding it and it seized up.  the kick start became completely stiff. ( didnt put oil in the bike , thought mixing oil in the gas covered that -[ young and dumb / live and learn ]-
and since than its been sitting in my parent basement.

So the question is, is the engine savable?
1993 eg8 civic - rust N' crushed
1993 eg8 civic - seized, taking a snow nap
1998 DC4 integra - daily driver

    Quick answer, no. Either find a new engine or that one will need a rebuild.

      I've rebuilt every 2stroke that I've owned, parts are super cheap, and it's so easy to do. A rebuild will most likely be cheaper then a new motor.

        Rebuild.  Thank your stars it's a 2 and not a 4.

          Exactly this, 2 strokes are relatively easy and cheap to rebuild.

            Depends on the condition of the cylinder and what type of material is used to coat the liner. Not to mention since its been sitting there seized for years you'll need to replace almost all internal wear parts, and most likely recondition the crankshaft. Personally sounds like a waste of money and might as well trade the core in for a new one, probably end up spending the same
