Chances are strong the bike has a bent shift fork. This is a major repair requiring a complete engine tear down. As far as the leak goes, there is a shift shaft seal, drive-shaft ( sprocket shaft ) seal, Kick shaft seal. shift drum switch seal, crank shaft seals and clutch shaft seal. Also, there is the right outer case cover gasket, oil filler "O" ring seal, and the center case mating surface seal. The center case seal is actually a semi-liquid gasket compound applied to the mating surfaces prior to the center case re-assembly. The shift fork repair is not recommended for the unexperienced home mechanic. Below are the main parts if a Suzuki shift mechanism and a diagram of how the shift forks move left and right to change gears. Please rate my answer. Thanks!
I had the same problem. The bike sat for a long time and when running again it would only shift when the bike was on the stand. When is was on the ground it would only shift into first, could not put it back into neutral. I drained the oil and bought some "Rislone" an engine treatment at Canadian Tire and let it sit for about three or four days. The next time I tried the bike it was shifting perfectly. Just gunked up from siting for so long. Before you go spending a huge chunk of money try this stuff. It worked great for me.
The owner didn't say the that the bike had been sitting. Glad your bike is operating well now. You bring up a good point, extremely dirty oil can create problems.
