Big Bore Kit
I have done some searching around but I cannot find a Big Bore Kit for the Duke/RC 390 anywhere which blows my mind as these bikes are sold in huge numbers all around the world. I'd think that whoever makes a decent big bore kit would be on to a good thing. I'd love to have a Duke 450!
Perhaps I have not been looking in the right places; does anyone know of any big bore kits for the 390?
