on my quad the large cog on the rear axle that the chain goes round moves back and forwards with your hand (hence i can't tighten the chain properly?) but it don't move on my others,  any one know what the problem is ? cheers.....

If I may suggest...Add your post to the MXU section further down the forum list.  This forum caters to most all Kymco fans.   Unfortunately most of the Forum users have scooters.
