So i left my bike in the dumpster area locked up while i was working, it got rained on a little and i pulled the clutch back and started to ride when the back wheel just gets locked up. i cant push it forward nothing, so i checked the gears in the clutch case and they seemed to be rolling fine backward but not forward. Ive been trying to fix it the last four days and im starting to give up hope. its the only thing i have to get back and fourth to work, it would be great if a more experienced person gave me some help on how to fix this.
