Why do you want to run dual chains? I guess it's for looks, because a modern 530 chain will handle much more power than our bikes are capable of, even with heavy engine mods.
An offset dual chain setup might cause some clearance problems on the other side, (frame/sprocket cover/rear shocks etc, I presume you won't be running a chain guard) and might also require an "outrigger bearing". Cheers, Terry.
