Bodywork, fuel and oil tanks, forkbrace

The bodywork is dual-layer carbon fibre with ribs to reinforce. Weight is approx 730gr. It's underside is molded to the shape of the frame and fastened with four cable ties. Here it's pictured freshly painted on 11Jan11 and before the signage and sponge rubber padding is added. Painted with spraycan using discount paint from Supercheap auto.

The brass tank holds 600mm and is fabricated with easiflo weld. The two nylon pushlok fittings 1/8bsp>6mm & 8mm on the left are for filler and breather tubing. The pushlok fittings have survived the methanol after three days racing at Meremere. Am monitoring very closely for signs of leakage and/or failure.

The polycarbonate tube is the engines' oil reservoir. Approx 500ml of oil is used for the entire lubrication system. This includes what's in the crank, pump and oil galleries. Engine runs a dry sump set up with stock Triumph twin-plunger pump. I drain throroughly after each run to ensure any methanol is removed. Methanol attracts water so it's quite important. The tube is capped at the lower end which I glued with epoxy. This was a mistake as it re-acted with the polycarbonate, forming several faint hairline cracks. The filler end has a rubber o-ring to facilitate oil return, breather and top up. Again nylon pushlok fitting are used being superlight.

The fork brace pictured has been recently lightened with holes to its' midsection. The brace itself complies with regulations and in my opinion doesn't actually do much as our front end is extremely short. It's fastened with 6mm titanium bolts and alloy spacers to ensure the tyre has proper clearance for the growth that they get at terminal speed.
