just followed this guide on my 2011 vfr800 with only 40,000km it had started to rattle after a low side, then a 6 month sitting in the garage while my bones re grew. (insurance did a full new set of fairings and panniers and anything else with a scratch on it and i did an oil change before the first ride)
i found it surprisingly easy, as i was also doing a coolant change too, i just did it when the coolant was drained out of it.
interesting i was sure it was going to be a noisy front one, so i did that first, starrted it up, rattle little quieter but still their, so i did the back one, which i found the hardest as it leaks oil and the key wouldn't stay in so i had to hold it in place while i undid it.
started it up, very very quiet. like a new bike again. except with the full motard decat system and debaffled stain tunes.
