Buying a Used CBR 600RR: Mechanical Question

Hey everyone,
I've recently stumbled upon what is seemingly a great deal on craigslist. $5K for a 2006 CBR 600RR, with approximately 1000 miles. Long story short, this owner bought it from his co-worker (surgeon at a medical center) who never rode it. Consequently, the second owner (guy I'm buying it from) acquired after it had been sitting for about 4-5 months and the fuel had gone a bit stale. The second owner decides to ride it anyways, for whatever reason, and 200 miles later has small problem with fuel starvation on a low tank. He jiggles the bike a bit (causing the fuel to slosh around) which fixes the problem, drives home, and calls Honda. They say that, due to the low mileage, the cause of the dip in revs is most likely a mucky fuel-filter (caused by the old fuel). They say he could replace the filter for about $120, but he never does it, and instead puts in some fuel-injection cleaner as per friendly advice.
About 600 miles go by and he hasn't had a problem since. Now I'm about to buy the bike, but before I do, I want to know what possible ramifications his lack of filter cleaning could have caused. Should I worry about problems down the road? Could the old fuel have damaged the bike at all? The bike is fuel-injected.
Other than that little detail, it's a showroom bike. The guy (who's about 40) is selling because he already owns too many toys, apparently, and never rides it much anyways.
Any advice it greatly appreciated.

Check the tires. Make sure the date codes aren't past expiration and if they aren't, that they haven't started to dryrot.
Things I would worry about a bike that has so low miles/sat for that long.
1) The fuel filter and the Electronic Fuel Injectors (EFI)
2) The quality of the seals. If the engine sat for years w/o oil on the seals you might have a problem there.
3) Make sure the brake lines are not degraded. Brake fluid is caustic stuff.
If you do buy the bike I would drain/change all the fluids. If most assuredly needs an oil change anyways but I would also be Leary of the brake fluid.(expect about $150-200 at the dealer as it's a fully fared bike)
PirateJon is bang on about the tires. Also make sure the chain is tight and lubed before you ride it.
Yeah a rusty fuel tank will continue to cause problems, even well after you've changed the filter and fixed the problem. That being said, a vast majority of fuel tanks these days are plastic, and many of the metal ones have plastic lining the interior, so a quick check should be able to tell you the condition and whether or not any rust exists.
Change the filter (do it yourself - it's not hard, and there's no justifying $120 for a filter change from a dealer/mechanic), get some new fuel in there, and see how it runs. You'll know fairly quickly if the injection system was damaged or dirtied from the fuel. Though quite possibly, as long as the first problem was just bad fuel and not something else, the injector cleaner the previous owner used probably cleared up most of the problems.
All the other suggestions are good, though really they pertain to purchasing any used bike. Tires, chain, fluids, all that stuff.
I'd have them take a look at it, and negotiate -$100 off the price and see where it goes. If nothing is wrong you win, if it's jacked up you just eat the $100 and don't get boned.
I do want to add that he has been riding it since the single occasion of sputtering (for about 600 miles), and claims not to have had a problem since; so fuel has been cycling through quite often I'd imagine. I guess it'll be up to my walk-around inspection to determine whether or not I get it.
musaman, I'm not quite sure where route 4 is relative to where this guy is located (Victorville), but I will try and see if we can get run-through of the bike with a mechanic.
