I'm pretty much echoing the above sentiment; List it "as-is" with enough of a chunk off of the asking price to cover the cost of the repair. I'll disclose any major issue the bike might have, but I'm not going to hold the buyer's hand through the repair process.
If it's someone like me; I'll take on a project that needs a little work, if it's a really good deal. But then, I don't pay for someone else to turn wrenches.

I guess the calculus is whether the difference in $$ you could get for it in "as-is" and what it would fetch at 100% is worth the time (and parts) to get it there.
