Went for a ride today and noticed that the gearlever felt as though it had plenty of play in it. To my suprise the lever that comes out of the gearbox was very very loose and had a lots of free play. After nipping it right up, a easy job i had a look on the internet and sure enough this is common fault and if you dont jump it on now can strip the shaft and then its a major to get it off. Go and have a little look before your next ride.
