Decided not to build a 2nd 250 so I'm parting it out.  Selling a motor off a 90 250.  This was a good running motor that I was riding on until the crank seal gave out.  I pulled the motor for repair and found the counterbalance drive gear was missing a tooth.  I was about to buy a new gear set and ran across a deal I couldn't pass up on another quad and decided to part my 2nd 250 out instead of building it.  The shifter shaft is bent but the trans shifts fine and the case saver bosses are broke.  It also has a crappy black paint job.  I've got a set of new Suzuki crank seals I'll throw in.  The clutch fibers and steels look relativity new.  All the clutch parts, kick starter, clutch and stator covers are included just not pictured.  I can get more pics if needed.  Looking for $400.00 OBO shipped to the 48 states.

What bore is the cylinder on?

No clue.  I've never pulled the top end apart.
