I tried to start my GPX today, after 2 days without using it and it wont start. When I pressed the starter button it just made a clicking sound. At first I thought it was the battery or starter motor, but I checked them and I think they're ok. Then I realised that if I put it into 1st then held the clutch in, the bike was really hard to push (not as hard as if its fully in gear though). I can still move it around in neutral though. Any idea's what the problem could be?
