[QUOTE="RaYzerman19, post: 1105495, member: 18388"] I would agree with all said about how the clutch works..... also have a Gen 1 slave and Pazzos, which must have lever on 4 for clean disengagement (especially when cold). To test your condition, try the lever at 5 or 6. This may alleviate drag when cold and that little lurch forward. Still doesn't fix the problem, as you gotta have long fingers at 5 or 6. All it does is make the slave travel a bit more, indicating (to me) you should re-bleed the line with the traditional method, teflon tape on the bleeder threads, and make sure you pump enough fluid through to clear the slave cylinder and line. If the clutch plates are worn, they are thinner and in theory it should take somewhat less slave stroke to release it. Springs weak should only cause slippage, although worn plates and an oil issue may also cause slippage. Basket springs are for damping not engagement as Fred said. The other possible issue is clutch plates sticking. I realize you said you're using the same oil you always have, but doesn't mean things haven't gummed up over time. To help clean it, you could add a cup or two of ATF and a couple ounces of Seafoam to the oil and run it at full operating temperatures for a while, more clutch strokes the better. I wouldn't recommend any hotdogging while it's in there, but see if anything's changed over the next 200 miles. Then drain, new oil. Not that I want to start any more oil debates..... but in my experience, Amzoil is known to have good clutch and buttery smooth shift performance if you want to try that once. All that said, a 180k clutch doesn't owe you anything. I doubt you have to replace the basket if you don't see any noticeable wear in the grooves... shouldn't be much, it gets plenty of lube........ if you go with new clutch plates, don't lose the little ball or anything that would effectively make the push rod shorter. And I'd do release springs while I was in there. [/QUOTE]
