When bike was about 7-8 years old finally got around to replacing fork oil with new 10w the grade it said in manual and the handling went from wobbling round corners like every wheel, swinging arm and steering head bearing had collapsed to feeling like it was on rails. Replaced the fork oil every couple of years since I didn't want it in the same state it had been before and tried 15w for the last change a couple of years ago because people said it was a great improvement but I didn't notice any real difference.
