I was wondering what the typical amount of mileage you guys get out of your stock clutches. I have a 99 F4 with about 13.5K miles on it and the clutch doesn't grab till the clutch lever is almost let all of the way out. I've adjusted the clutch lever as much as I can, but it is still late to engage. I was also wondering if there are any aftermarket clutches that you would recommend, and how much time and effort it would take to change it myself. Thanks
