I was washing my bike the other day and noticed a small crack in the sightglass window. It's not leaking oil but I am a little concerned. Has anyone had to deal with this and is there any alternatives aside from replacing the side case. Jerry
oil sight glass Halls has that part (#800073529 oil inspection cap) in stock for $16.50.You might want to double check with them over the phone just to make sure that is the right part (217-789-0107).
