Gotta echo the coments about the type and quality of the work done to this machine, but this is NOT the bike for me.
Love the things you've done with it, but I'm not an IBA type.
I love the Hella Micro DE Xenon driving lights. I have a set mounted on the FJR, having had another set on the bike's predecessor, may she rest in peace.
The biggest issue with mounting an externally ballasted fixture on a Gen-II FJR is finding a home for the electronics - been there, done that - it can be squeezed in - one sits behind the glove box and the other is between the plastic and radiator.
If you wanted to go to a Chinese miniature ballast you could certasinly find more places to stuff it at the expense of long term reliability.
Someone here cut the cabling and ran high voltage cabling from the tail of his bike . . . I strongly suspect that doing THAT would cause all kinds of electrical noise, impacting on an Autocom or even affecting a navigator, depending on the spectral output of the unshielded wiring. It seems to work for him, though.
