I have seen a picture of a bike with the same lighting setup on the internet before.
I am pretty sure its an ex Kawasaki works bike, I am sure that Varners Racing do the tuning on Destys bike (well one of his bikes had a Varner sticker on it in the picture I saw anyway) and if you look at the side of the carburetor it has the sizes of the jets written on it like the works bikes do.
I expencted it to have the seperate clutch cover but it doesn't.
I wonder if its anything to do with Charlie Haplin?
