Got my clutch cover opened up today and took out my friction plates. All very clean in there which I was happy with, no emulsion etc and basket bearing felt very smooth and had no damage.
As for the plates, I am not confident to really say as I have never taken a clutch apart before nor seen what a brand new clutch plate looks like. On first inspection, the actual plates don't seem too bad. There is quite a lot of the friction material on most of them and they aren't flat. The steel plates aren't blued at all for the most part, only one of them had some slight marking. However, strangely there were 2 black friction plates in there. One was right at the front so the first one I removed and one right at the back. These to me felt a lot more worn than the rest of the plates, the larger internal diameter plate where the judder spring sits inside is also a black one and feels more worn than the other brown coloured ones. I checked the haynes manual and apparently thundercat clutches have a black first and last plate, but so do FZS 600 02-03 models which mine isn't. So, is this normal? It says if any are worn, the whole lot need replacing as one whole set and to me these black plates feel worn or at least a fair bit more worn than the others.
One last thing, apologies for the terrible photo but are these the standard clutch springs? They had a lot of yellow on them so not sure what thats about. May just replace them as well as I don't have a vernier caliper to check if they are still within tolerance. They could be what's making it feel a bit "weak" at pull away and slow to retract on some gear changes if im not careful. If anyone can fill me in with any of the above I would be very happy, thank you. Some pics:
