I had the old cover replaced on my Busa with a chrome one. I had this done about a year ago. Recently whiled transporting my bike on the bike of the truck. I noticed a oil leak. It just so happened that my bike was leaning a little to the right. The o-ring around the sight glass is pushed out just a little. Is this a repair that I can do myself? I am mechanically inclined. Is there any special tools that I may need?
