I can't find it now.

Ben,

It might have been me. I did some swapping out of front end components on my 90
PC.

I am currently using a Suzuki GSX 600 MC that uses a 12.7mm piston; Honda (from
the 80's and 90's at least) used a 14mm piston.

Here is a link talking about setting up your ratio:
http://www.vintagebrake.com/mastercylinder.htm

I found I liked something around 20 or slightly above this. I first started
playing with components on my GL500 Silverwing as I found the Honda parts
surprisingly modular and interchangeable. I ended up with CB900 discs (bigger
diameter) and different calipers. I also swapped out to the earlier comstar
wheels from a GL1100 and got the rear disc brake - it was big!

The ST1100 front end is similar to the PC. If you wanted to upgrade the PC
brakes, you can use the larger diameter ST1100 discs but need the ST1100 caliper
brackets. You can reuse your current calipers as they are the same as the
ST1100. Your would, of course, have to remove the front fork plastic covering on
the brakes as they will no longer fit (bottom piece anyway). I would say if you
have a 97 or 98 PC, this mod is a no brainer since the front fork came naked.
Throw in a set of SS brake lines and a 12.7mm MC and you will be very happy with
much better brakes.

Of course, I am experimenting again, so I will tell you how that works out when
I complete the project (front end swap - again)...

Jerry

not.

    Just a couple of observations from my own experience. Old brake fluid feels spongy. Until I changed mine, I was considering braided steel lines. Not anymore. Magura I believe still makes levers that might fit the PC. When I've used them on ot

      I noted the other day that even with 3 bulbs the rear end is not especially bright. On my ST1100 we substituted halogen bulbs that were something like 15/50 VS. the 5/15 watt stock ones. Not TOO bright with running lights but very noticea

        I'm waiting to go all LED. We were ultrasonically test welding a new car tail light housing with 80 LEDs in it. I scavenged the LEDs out of the scrap, so now I have several hundred bright LEDs. That will be my next project. Dave --- In

          I want to go that route at some point in the future when I have the money and shop space. I was thinking of using the stock housing as a template or mold that I could then lay LEDs inside of and cast new resin lenses... or something along tho
