As for the regulator it comes from Compufire. bought it on Amazon.
the unit is a bit different than the original one.
a bit longer footprint
and a bit thicker
So in order to install it, I had to extend a little bit the bracket. you see the original hole (the one in the middle, and the new one on the left, just solded a little piece of aluminum to extend it.
As for the thickness, it doesn't bother, it doesn't protude out of the frame.
you can also see the new exhaust wrap.
