After 5000 miles on my fz6 my head baring has broken. The warranty has expiered by a couple of months and iI now have a bill of around £170. I am not an aggressive rider in the fact I don't wheelie down the roads. I was wondering if anyone else has had this problem? I was wondering if i was to put thicker oil (MOTUL FORK OIL EXPERT, MEDIUM/HEAVY 15W ) in the front forks would this give me less dive when applying the breaks therfore cause less stress on the front end? PLEASE HELP!
