I have had a 2002 for about four years. Im on my second engine after racking up 70,000 miles on the first one.they are one of the most reliable bikes on the road. parts are relatively cheap now. and carbs are a lot less hastle than fuel injection. So my my advice would be go for the 2002 bike. 

I can squeeze 218 miles out of my tank with some careful filling up. But forget about going fast lol. As soon as i start to play it drops to around 160 miles per tank, But i still get there before my mates on their race bikes due to the fact they get really lousy mpg and need to stop at every second or third garage.
