I would love to play engineer here! But alas, there are other problems.
I would personally like to keep the rear giving 1 piston up front some lovin, but if it meant getting USD forks, I guess I could give that up.
Your system is actually pretty simple. And other than the 1 piston in the front, I don't see what the issue is.
Slap some SP2 forks/brakes on, get the adjustable PCV, and run SS lines throughout. :goofy:
As mentioned it would no longer be so speed sensitive, but that's the price you pay for shedding the only overly complex part of the system, going from back to front. I've started a thread like this before, and the answer was just a simple "no". But I'm glad you want to look into it!
I wanted to keep my original functionality, possibly by stealing the forks/brakes off something that came with what I wanted. With a great lack of outside help, I came up with only two options. Concours 14, and the VFR1200. Neither would be particularly affordable or readily available. And the Conny has electronically controlled (and adjustable) linked brakes/ABS.
