Just bought a 92 gsx 600 for last owner said it needed a new start button and a good carb cleaning to allow the choke to move more freely so I cleaned it. Buying a new battery next week. The bikes been sitting for 5 months prior to my putsch so I drained the old fuel out the gas tank and carbs. Any other suggestions in what I should do. Basically what are the basics I should cover before calling a mechanic,?
