Runner, you'll hv no regrets... :icon_thumbsup:
I've been doing other things at the same time so I have quite a bit apart... but I think at minimum, the windscreen and dash. I didn't remove the dash completely, just removed the mounting nuts and moved (w/harness still connected) towards the triple to get it out of the way. I also re-routed the large harness that you see in the picture away from the where the ballast was installed and moved it going through the center of the stay. If you use that spot for a ballast, one of the windscreen bolts will be very close to the corner so just be aware of that closeness when doing your final securing. Also, it'll be even trickier if mounting two ballasts under there. :icon_shifty: It can be done though, just trickier.
I'll only use one set on each bike
