I just bought my son a Suzuki JR50, I think its a 2003. It doesn't run and needs some work. The oil tank is missing, no kick starter, been sitting for ages so the carbs need a cleaning. It doesn't have the owners manual, so I'm wondering if you guys could let me know some of the stuff I should know about the bike. What fuel to run? What oil to use? What spark plug (I want to replace it but I'm not sure if it needs it or not.) What are the stock carburetor settings (I'm not sure if they have been tinkered with or not.) I assume since it has a centrifugal clutch that I can't push start it, hopefully I'm right otherwise something is messed up since when I put it in gear I can push the bike without spinning the engine. Any general tips or tricks you have about the bike would be greatly appreciated!
