Simon check this site out..
http://mrmoly.com/ .. was recomended by a sales guy from Atlantic British and have been using it ever since.. I think you need the Mr. Moly Gear suplament for the gearbox on-top of your gear oil of choice.. I think it works well that I even use it on my Ducati ( dry clutch motorbikes only pls ) There are tubes of Lubro Moly that Mecedes and Porsche race teams use but kinda priced up there.. Hope this helps..
