Thanks God, by chance I found this site! I therefore atonce implore & beseech someone listening to please help me. My shiny Norton Commando 850 bike that I love so much collect oil in the clutch chamber when left standing for few days! I am going bonkers to imagine/locate this hole, crevice,joints, etc as to where does so much oil come from afterall? I have an oil-cooler that feed the head first,thats the only foreign body to report to a standard bike. This is a shot in the dark but maybe some one will respond, please. I live far very accross your world in Karachi, Pakistan. Thanks for this lovely site.Very good wishes to you all. Nasir Khan.
