Johnny,
I think as the F2 had them anyway then it is a good idea, especially where safety is concerned. If you don't change the bike so that it can not be put back to original, then it doesn't matter anyway.
I would love to put twin disks on mine, but it appears to be a very involved job?
Strangely enough, I already have a F2 brake master cylinder on my bike, not sure why.
Have you already put braided hoses on, I am told this is a major improvement and much easier to achieve?
Cheerrs,
Jim.
