I lost the tranny-side crank seal on my bike a few days ago. Upon diassembly it looks like it started sucking air after it ran out of tranny fluid to burn. There are light scratches around the bore of the cylinder, slightly more so toward the top of the cylinder. Actually, I can't tell if they are scratches or if they are aluminum from the piston. It was making an ugly knock just before I shut it off. I can find no play in the crank bearings or the con-rod. Could the tranny fluid and lean condition created the knock or is it the piston? The piston actually looks really good. Would it be okay to run a hone up and down the cylinder to clear out any aluminum and put it all back together or should I get out the big money?
