For SAFETY reasons, the first thing you should inspect is the SMC, as this can lock up without warning and pitch you off the bike!
Most dealerships don't even know what it is, or how to inspect it, or worst yet, inspect it incorrectly, putting you at risk.
The second most important thing you'll want to check is the ECU (No longer available)
Start the bike, and bring the RPM's up to about 5,000 and hold it there for about 20 seconds. If the FI light comes on, there is a very strong chance that is why it is being sold so cheap.
It's either a bad ECU (again, no longer available) or a crispy damaged lower sub wire harness.
I'm thinking there is a reason the bike is priced as such.
Some dealers/owners have be caught clearing the codes, and only showing the bike at idle, and not allowing test drives, or raised RPM's to hide this fact.
Buyer beware.
Again, I can walk you through the inspections on the phone if you need help.
