    Is that Kevlar laid up and resin-ed in the same style you would normally do fibreglass ?

      Yes it is.

      Cut and layout fabric to ensure it fits.

      Layer of wax, then a layer of release agent.

      Put down some epoxy and then lay the fabric.
      Squeegee and roll to get epoxy through.

      Rinse and repeat till finished.

      I generally go a bit over on the fabric lengths.

        Cool, I was wondering how you got it off after it set.
        How strong are you finding this kind of shield in practice?

          I've had one on my Familia for the last 12 years and it has not missed a beat.
          I have reduced the number of layers on this latest incarnation to see how it goes.
          Slightly more protected than the familia one so hopefully less prone to rocks.

          The underbody on the familia is also too thick, so I have scaled it back on #RallyRolla also.
          No problems. When it wears slightly, I just scuff it up and paste some more epoxy over the top.

          I have found it is best to put a sacrificial layer over the good stuff to offer wear resistance and a little strength, although it does add to the weight.

          I'll stick a layer of Kevlar and then a layer of woven mat on the underbody and sill guards this week to add a bit of bulk and piece of mind.

          Fuel tank and underbody from the familia.

          This used Vinyl Esther resin and not epoxy.

            This is what the underbody looks like after 12 years.

              Cool, thanks. Certainly looks to be doing the job - the idea of a sacrificial layer makes a lot of sense.

                Slightly lower is input from tank..
                Fuel pumps will feed line to fuel rail.
                Tank is only 1 litre in size.
                Seems to have been working fine for competition Lotus vehicles, so thought I would try my luck.
                Surely the tank is designed like all other surge tanks though... ie, pick ups are off the bottom of the tank when its stood upwards (normal orientation).
                There isnt much point in running a surge tank at all if the pickups are not on the bottom.

                  This, I don't get it either.

                    Seems to be working in these instances.

                    I spoke with them and detailed what I required.
                    They had a product they had used in competition that I thought would suit my requirements.

                    Happy to be proven that it is wrong, and does not work.

                      The obvious answer is they do 2 different configurations of tank - one laid over, with the pickups set up for such, and one stood up, with pickups to suit.
                      "Where can we get hold of a Vincent Black Shadow?" "Whats that?" "A fantastic bike," I said. "The new model is something like two thousand cubic inches, developing two hundred brake-horsepower at four thousand revolutions per minute on a magnesium frame with two styrofoam seats and a total curb weight of exactly two hundred pounds."

                        All good then.

                        I gather you'll run one pump normally, and use the other as a backup?

                          Yep.

                          Low volume pump into tank.
                          Run one pump as prime, and the other as secondary.

                          A bit of fabrication to create a sealed under floor area with a see through lexan port hole to show off the bling.
                          Also a separate fluid port so the floor can be removed with compromising the connections through the cabin.

                            So, have done a little more with the fuel pump area.

                            Fabricated a cover and viewing port with Acrylic so at least you can see what is hiding there.

                              So wire stripping has commenced.
                              There is a wire, and in some case 2 for everything.
                              Basic indicators, head and tail lights, horn etc retained.
                              Lots has gone.
                              PDM and switch being sourced from 10secrx7 to allow for no fuses or relays and to look schmich.

                                OK, been doing a little work behind the scenes.
                                This is all that is left of the factory wiring loom.
