Hi, Right you are about bleeding the air from the clutch hydraulics via pressurising the brake fluid reservoir from above, but I'd venture to say that you can usually replace the clutch without disconnecting the slave cylinder from the feed pipe. Which means that if you have no air in the hydraulic system _before_ replacing the clutch, you probably won't have more once the clutch is replaced. Which means that you should be able to avoid having to bleed air out of the clutch hydraulics. I've replaced two clutches on two 1983's (99GL and 900 GL) and haven't had to bleed the system afterwards. OTOH I work very slowly, takes about 4-5 hours for me ;-) // Robert "James H. E.
