| tbh, the shell fully synth has never given me any slippage problems, castrol and slikolene are the usual culprits..
When you say the matter is improved by unscrewing the detent in the lever improves things, are you running stock or pattern/aftermarket levers? These are usually the biggest culprit. especially the cheap pattern levers.
Try cracking the bleed nipple on the slave cylinder after pumping the lever a few times. If fluid comes out at anything more than a dribble, you could have a problem with the clutch hydraulics pumping up. |
