We've got a rebuilt 680 Ultra engine for sale. This engine has about 50 miles on it since it was rebuilt. The reason the engine is out of the sled is because the sled needed major drivetrain/suspension work and a part out was easier. This engine has a trued and balanced crank, new pistons/rings, OEM Polaris gaskets, a light port cleanup. This engine comes with the reeds/cages/carb boots, ign. coils, stator and flywheel, and the fuel pump/shutoff. It has quite a bit of oil in it for storage, but it does run very well with triple pipes. We'd like $450 for it, but we're open to offers. If you have any questions, call (218)-829-7774, or send an e-mail.
