Hey guys, first post here after reading this forum for months on end.
My bike G650X Challenge 08/09 model.
Probs: 2 x faulty batteries replaced on warranty, latest battery was replaced with the Yuasa brand.
Fuel pump wiring harness. Riding along then completely cut out - 140km from anywhere had to fault find it and temp fix it with the horn spade terminal. The spade terminal in the plug onto the actual fuel pump had broken. New harness on way.
Otherwise very happy with bike.
