At what witdh you have to change your belt? a new belt is suppose to have between 29.2 millimeter and 30.4 millimeter I don't understand why on Kawa site they put 2 sizes when it is new there should be only one size. Anyway they mention to change the belt at 28.8 millimeter so betwween 28.8 and 29.2 there is not a big difference ............I already change mine at 500 miles and now I still have to change it at 1600 miles. For a new technology quad I feel that we have to change the belt very often. This is done by my dealer. Other information what is the belt deflection (between 22 and 27 mm) how do we adjust that ?
