the 74 z1 turbo project again

Around here, most guys rake the frame by cutting about an inch out of the top tube under the tank and then pulling the neck back til the tube meets up again. Then weld them together again. I have a frame like that and a stock tank won't work. Will have to move tank mounts back about 1/2 inch to clear the neck. I prefer to remove the neck and weld on another in the desired rake or some will cut the stock neck down the side at the desired rake and then weld another neck tube onto the cut neck already on the frame. It's the harder way to do it but, in my opinion, it's the best way to do it.
