Seized engine kz440

The oil light didn't come on, it was 100 percent my fault for not checking sight glass before ride.

Where would I begin? I think replacing the motor might be in my skillset i don think rebuilding it would be. I got it to turn over and almost run briefly, Sounds like rings are toast and maybe valves? 

That's very true. the engine I'm looking at is from a reputable seller on Ebay. only testyed for compression and maybe starter. kind of a coin toss I suppose.

ill most likely keep it as a reminder of my idiocy lol

i'm not seeing direct instructions for replacing the entire engine. I believe the manual I have is a service manual. Is there a more specific shop manual?

There’s not much to an engine R&R.  Basically unbolt or disconnect everything connected to the engine (chain, clutch cable, exhaust, carbs w/air-box), remove old engine, bolt in “new” reverse the process.   With a 440’s engine size, you should be able to remove the engine relatively easily due to it’s smallish size.  Only advice is to make sure it’s supported well underneath before removing the last few attachment points.
