About to order the three oil filter cover bolts (hex head 5mm) on my bike which as far as I know are the same on alll other 2006 yzf450's. But when I looked on the thumpertalk parts diagram it seems that part numbers 6 and 7 aren't hex just the lower one, which on mine is a slightly different shape. Just asking if there is a reason for these parts being different or is the thumpertalk part diagram messed up ? cheers dudes. I don't supose them having different heads will effect anything ?
