Pictures please !!
Do we (tony w ) have any theorys as to why yamaha are saying 98s are ok and do not need the nut mod. Are you measuring the shaft including the tops of the thread. Someone on here measured theirs to be 17.5, could it be that the first bikes off the factory line sold like hot cakes and they said oh crap we are gonna need a shed load of parts, which came from extra- different suppliers. So all the 98s are good and some other 99s onwards are not, depending on who supplied the blank shaft that yamaha then cut the thread as if it were a thicker shaft meaning that the threads were not deep enough. And the new nut as you say is cut to fit a 17.5 shaft and it that that is the inportant mod and not the fact that it is 12mm instead of 9mm as the extra 3 mm does not do anything as it sits over the tapered end of the shaft anway. Yam spec loctite 620 which is a very strong thread loc http://www.henkel.co.uk/fullproduct-list...000000IZEY
