Clifford, i for one am good to go with replacing or in my case repairing what was in there - the stock MCI double plate clutch with a floater disc. I just would be lost trying to select and set up a single plate clutch with a different thickness, etc. I agree with you that a single plate clutch would probably be fine, but mine had unknown but high miles on it, was in great shape and the grinding marks on the plates and flywheel were still perfect. That reliability and length of service is good...
Fredward, yes - pedal height is what I suggested you check and adjust. Yes, thicker floor will make a difference. Heat will make a big difference - mine is quite hard to engage first when it's fully up to operating temp. You just shift into first before you stop, and wait at the light with your clutch foot down and your leg starting to hurt... I think the double plate clutches are inherently draggy and will keep the gears rolling inside the gearbox for a long time. Mine can take 30 seconds before I can shift into first. You can shift into any gear, all you need to do is get the gears stopped, use third or fourth if you want to save wear on first gear dogs. We really need a clutch brake, or a gear brake. I was designing one last year, but gave up on it.
