Hi all ,last week I filled my pair of Hans damps with helium reason being there is this jump I just could never get !! Well after the first attempt with the helium fill tyres all I can say is I overshot the lander by six feet. Has any one else tried this?? But with every pro there is always a con ! When I arrived back at my home I untied my bike and it floated up into the power lines disrupting the neighbourhoods power supply .
