I wouldn't recommend using an alloy clutch basket with the MK3 chain drive primary. A couple of decades back I tried using an alloy engine sprocket and clutch on a 750 Commando racer, and the sprocket teeth on both wore out almost immediately. I think it was from Fair Spares, but I'm not sure after so many years. It might work better with one of the modern high tech surface treatments to provide a much harder wear surface. I don't think the one I tried was even anodized, just bare alloy.Looking at the Phil Pearson and NEB clutch baskets, there is a potential for saving another 1.5 kg / 3.3 lb or more by replacing the stock basket by one made of aluminum. This is another Mk. 3 part crying for a modern replacement (I am not considering a belt drive).
