Tear into it, or bolt in and go???

rattle-bomb rebuild baby!

blow it apart, give a everything a hairy eyeball and if it passes the sniff test do gaskets. check the cam and see if there's any ID on the snout. degree that puppy and snap on a new chain and oil pump & screen. knock in new core plugs, blow some paint on it and call it done.

you're out a few hundo and the weekend.
