All my gears were fine, but my clutch cable loosened off and this made it difficult to select 1st and second gear, i forced them in and now 3rd gear does not work, it just grinds and the gear leaver shakes. I tightened clutch cable and all other gears are fine but still no third. Hope someone can help!!!!!
