As the title says, I'm a dumbass for grinding the old chain off before breaking the allen nut and sprocket nut loose. Should I wait until my new chain comes in and put it all together and then break it loose or is there another way of breaking it loose without having a chain on it? Also, when I removed the cover for the front sprocket the little seal was left on the shaft and I accidently pressed the clutch lever and fluid started coming out I noticed it was pushing a little bearing out from looks like a fluid housing in the cover so I pushed it back in and put the seal back in and put the cover back on and now there is no lever pressure. Have I let air into the system and need to bleed the clutch? Thanks.
