I was working on my 2007 brutale 910 r and was removing a piece of asphalt that was stuck in the front sprocket cover.* I had to remove the front sprocket cover and was being care not to remove the cylinder rod but as I was holding it in place it slipped from the pliers and slid out with the cover still in place in the slave cylinder.*It seemed to be stuck in the slave cylinder. I placed it back in and put the cover back on.* I started the bike and the clutch worked fine.* It went in into gear no problem and I was able to go back to natural.* I was nervous to take it for a ride.*I am unsure what to do. The piece of asphalt was almost glued to the inside of the sprocket cover.
