Hey guys me again lol, Iv got major chatter in the rear when the rims are on! but when Iv taken them off it sweet as????? Iv tried other rims would this be because the rims are out of balance? also I have stirrped the front centre pulley and its damaged the centre belt aswell "few teeth missing" I think I may have done this because by tightening the rear rims on to tight???? cheers
