    Looks like they used fuel line, most of which is not compatible with brake fluid. Brake fluid is surprisingly damaging stuff to a lot of materials.

    I had to make one of these cheapie M/Cs work a while back, and after a few failures I did some testing with several samples of tubing from my stash dunked into brake fluid overnight. I ended up using a chunk of translucent yellow Tygon tubing normally used for fuel lines. In order to form the tight U-bend without kinking or collapsing the soft tubing, I pushed the Tygon tubing over a piece of copper 1/4" tubing and dipped it into boiling water for a minute. A quick dunk in cold water to cool, and the "U" shape was permanent.

      as said before get a combined master cylinder and reservoir, junk the chinnese stuff.
      What was wrong with your original master cylinder?
      Nothing was wrong with it just wanted to go with a different style lever. I'm also running pods, header wrap and chopped fenders if your looking for something to criticize.

          Bingo. You need to use a non-hygroscopic hose. I doubt the seals inside the MC will be an issue as they will be sourced from a brake supplier.
          Current:
          Z1300A5 Locomotive (swapped my Intruder for it), GS450 Cafe Project (might never finish it....), XT500 Commuter (I know - it's a Yamaha :eek:)

          Past:
          VL1500 Intruder (swapped for Z1300), ZX9R Streetfighter (lets face it - too fast....), 1984 GSX750EF, 1984 GSX1100EF (AKA GS1150)
          And a bunch of other crap Yamahas....

            Im going to try the route of a different OEM unit.

            Ive always had tremendous success with RC51 (SP1) Honda units - very high quality, 19mm piston , cheap on eBay

            used them on race bikes, road bikes, with 2-6 piston calipers ........ great feel with progressive action and non wooden feel- A huge upgrade on hayabusa's , SRAD's,super hawks and bandits
            78 GS1000C- Now sporting 1100E suspension and numerous goodies

                Brian, what did you do with the copper tubing then? Just leave it inside the Tygon?
