i'd paint the magnum to match the jammer, personally.
looks insane. whats the mounts like? I mounted a jammer to my seca xj550 and had to build the mounts, it was pretty stable but not perfect. I later rode a vintage ex cop bike with one, with proper mounts and it was worse. Still it wasnt bad enough to really worry about and it was a great deal of fun having a big old jammer
I later id paint mine but just the stripe with some removable plastidip paint, came out rad
