So, I've just bought a 2000 Ninja 250 that doesn't run to fix up for my senior project. I'm in high school and just got into riding and decided this would be a good way to familiarize myself with maintenance, and just motorcycle parts in general. I've got little experience with engines which is another reason I'm doing this project, I want to learn. The bike cost me $170 and according to the previous owner was running until about three or four months ago. It seems like the engine has seized and I'm probably going to need to put a new one in it. The battery is good, but the engine wont turn over. I'm trying to complete this under $1000. Any ideas on what may have happened to the engine, ways to fix it, or tips on what to look for as I take on this project would be greatly appreciated.
