I'll explain little: I do alot of different stuff including: body work, welding, and make custom parts for ne thing. I need to know the weight of the two major lower fairings or belly pans for the hawk. Haven't worried bout weight building pieces for other bikes but have some pieces in mind for mine and weight matters now. I doin some mods to reduce weight to make up for lower fairing and then some. I want the most I can out of my hawk. What is the weight of the sharkskinz and the pryamid lowers?? I am doing 520 conversion, how much will that through speedo off?
