My 750 had been sitting against the outside of the house uncovered for 2-3 yrs before I got it, throttle cable was stuck, engine was froze, but some PBblaster in each hole and some patient wiggling back and forth finally freed it up and it runs great now. Since yours isn't froze, and was running when parked, you're way ahead. Once you get it fired up, add some motor flush to the oil, let it run til it's hot, then change the oil and filter, and I'd recommend pulling the pan off the bottom to look for deposits, very cheap insurance and you don't want to run 10yr old oil. Then the fun begins. My guess is you'll ride it around, get to like it, and never have time to take it apart.....
If you're really new to riding, it would also be a good idea to take a safety course first, and then test ride everything you can get your hands on, experience is the best teacher. Just always remember it is extremely easy to be over confident, and over confidence can kill you, and you'll be OK as long as you watch out for the cars. Best of luck, and More Pics!
