Exactly what I'm wondering about this entire used motor market!

Yeah, I have no idea, and since it was a mystery to the mechanic without him diving in further, I just took the cautious approach and said screw it, replace the whole engine, fearing that we could lose many hours trying to diagnose. But maybe that is overkill, so may go back and try to learn more about the original engine.

That's a good plan. The bike we bought supposedly ran. But when turning over by hand, it was extremely tight. Tried to start it but only ran for like 3 seconds. I think a rod bearing is seized. The rest of the motor looks fine.For your motor, It may be something as simple as tight or a burned valve. Easy enough to fix.

What were the numbers?

Motorcycle troubleshooting is a form of problem solving... It is a logical search
for the source of a problem so that it can be solved... it ain't about jumping to
conclusions... always eliminate the steps listed in the SV650 Shop Manual before
deciding action...

Easy. Plenty of things are worth more as individual parts than they are as a whole. If you get good at recognizing what qualifies you can make a decent buck selling parts of various things. The internet has made this much more viable for many people as you dont have to specialize in a particular thing and build a reputation you can just get a bunch of junk and list it for sale in a dozen places and see what sells. It ain't easy, profits vary widely, but some people make a living that way

Thanks all for the input on this one. Might just try and troubleshoot the original engine more. Will reach out to ebay to dispute the second engine.
Ok, this sounds hopeful. Come up with evidence/proof (pictures, quote from certified mechanic, etc) to dispute as many of these as you can.

Like:
in great mechanical condition - pictures, mechanic notes showing it isn't
in great cosmetic condition - pictures, mechanic notes
guaranteed to be fully operational - can you prove it isn't? pics/notes again?
Motor has 12, 361 miles - prob no way to dispute this?
The bike it came off of was never wrecked or laid over - again, no dispute here?
The motor runs strong - mechanic notes?
shifts through all gears smoothly - did that seem ok as far as possible to test?
Includes starter, stator, and clutch - came with all this?
There is some light rash as indicated in picture #7 - ok?
Compression check confirmed all within tolerance - not sure how to get a compression test of an engine out of a bike ... you are supposed to test them when warmed up. Can your mechanic confirm the compression?

I guess at some point it isn't worth it ... if you gotta pay your mechanic $350 to prove a $700 engine is no good ... maybe just skip it. But if the mechanic has already checked it out and is willing to document some stuff, might be worth it.

Another tip ... you can actually call eBay. Poke around the dispute pages, and there is a way to say you want to contact them ... they will send you a code and phone number ... call them up and you get a real person to speak with.

Tell them what happened ... and ask them what you need to do to provide the proof/evidence so they understand how bad this engine is and how inaccurate and misleading the listing was.

Be reasonable and polite (they probably makes note about this).

Get all the info, pics, notes into your case.

Yeah, I guess I was reacting to the statement that both cylinders were low on compression. In other engines I've had, the times when multiple adjacent cylinders lost compression simultaneously was almost always the head (or head gasket).

In this case, I'm really not sure what would cause both cylinders to lose compression at the same time was my point

See if you can get the actual compression numbers for the original engine. Who knows, they might be within the range of acceptability. And was compression measured with the engine hot or cold.

Great advice. After hunting around a bit I found an ebay help number. Spoke to a human and they immediately agreed that that seller should pay for return shipping and that I am owed a refund. Now I just need to wait and see if that turns out to be true. Thanks for the tip.

Got a call from the seller calling me a douchebag and telling me my mechanic is fucking me over! "that engine was perfect when it left! we did a compression test!" - repeated 10 times with swearing. "we are not paying for the fucking shipping". "why did you take the engine apart? why did you take the engine apart?"

At one point, she even said "i knew you guys were assholes when i saw where it was shipping to"... what does that mean? Everyone in Oakland is an asshole?

Are sellers even allowed to call buyers like that?

Don't engage, call eBay again and tell them you're getting threatening phone calls from them now, ask them to intervene and take over. If you see emails or phone calls from them, don't answer or reply.

If that's their decision, you're good. They will refund you and take money from the seller's account if he fails to pay you.

Agree on the above post, let ebay know you are getting threats.
