Well, the DRZ is a killer bike IMO. I have one, a 2001 "E" (electric start!) and it really is an awesome bike. Stock: good power, extremely quiet, electric start. Only bad thing is wieght (can't feel it though) and suspension is soft if you are either very aggressive or more than 180 pounds.
Once you open it up, it really rips. You can get 5hp or more just with a pipe, jetting and a new needle!
The DRZ is reliable, that guy must of really beat on it. I know of a guy with 10,000 miles or so on his, all HARD off-road. He changes the oil and filter every 3 rides, and he is 270 lbs (lots of abuse!)
Well, if you ever get one, email me for some good mods that are cheap and will prevent furhter damage.
