Yep test #1 after installing and adjusting throttle cables is to turn the bars from lock to lock and check for changes. If free play changes the cables are routed wrong, binding or to short. If you're happy fine but if the bike were mine I would be demanding it be fixed.Thanks guys - I went to the dealer, and he told me that when the handlebars are centred there is quite a lot of play in the throttle, and that is normal. He then proceeded to show me that when you turn the bars in either direction to full lock, the free play almost disappears. Well you learn something new every day!
