Took my PK100S out yesterday for about a 3 or 4 mile trip. Half way round the power started to diminish and I eventually had to stop. Tried Kickstarting it, but wouldn’t start. Eventually opened up the petrol tank, just to make sure it wasn’t empty, closed it and re-kickstarted and it fired up. Why would this lack of power happen, how can I prevent it and why did it restart when I opened up the petrol tank?
All help muchly appreciated
