While my brother was in Cali about 4 years ago, he bought a Ninja 500. He never did any modding to it, just bought it to have it. When he moved from Cali to back home in Chicago, he did not want to pay to store the bike in a storage place. So it ended up outside of my house with a tarp over it for the winter. There was no Stabil added to the gas tank. It snowed a lot that winter as well. Part way through the winter, the bike fell and laid on it's side for a while. The following summer, my dad and brother had no idea why it wouldnt run. Now, two years later, I have taken the state motorcycle school and want to buy his bike. In two weeks I will go to his house in Ohio and see if we can get it running. What are all possible things that could have and probably went bad with the bike? I don't exactly remember, but it either idles but does not drive, or it drives but will not idle. Any information to try would greatly help. It will be my first bike and, unlike my brother, I want the bike to ride, not just to have it. I tried reading through other posts but they do not deal with a problem of this magnitude. Thank You.
