The Capo now has 3D printed bungs in the swing arm pivot and the ends of the crash-bar mounts. They’re held in by 43-39-2, 14-10-2 and BS011 ‘O’-rings. And yes, the BS011 rings are the very same as those used on the fuel lines. So one day if the old girl springs a leak and needs a new fuel line ‘O’-ring by the roadside – no problem, whip out a crash-bar bung and pinch the ring! Next ….. front and rear axles then the engine mounts above the swing-arm pivot .
