Welcome.
At least you will be saving 1 K...
Ya since one had a salvaged title already i figured swapping the Engine and Drive train would make one nice bike, The bad engine according to the Previous Owner resulted from an oil pump that failed and running it on the freeway starved for oil until he found a place to pull off safely. (Supposedly only a couple minutes) He replaced the Oil Pump but said it made terrible noises after lol (Ya think?!) I havent attempted to start it or do any investigating as to the level of damage.
Since i have the other engine i will just swap it and not mess with the broken one. Maybe collect all the spare parts into a complete bike with salvaged title and sell it for $500 if someone wants to tear into the engine. Or part it out completely and make a boat anchor or scrap metal out of the engine.
