Clutch woes

Well I have been going through my 996 and have been doing some neglected maintenance on it. Did the belts, plugs, oil, brakes, etc. was looking at clutch and saw the rusty springs. When riding it I swear it would go into 4th or 5th on occasion. I bought the Barnett springs and changed mine out. When removing the old springs I discovered a broken post on the inner hub. It was definitely cracked and just pulled off with not much force. So I replaced the other 5 springs and am looking into ordering a clutch or just a replacement hub. Went to move the bike today and it is super difficult to find neutral now and it also starts pulling in 1st. As soon as it’s in gear it pulls and needs the brake applied. If I don’t let it go it stalls. It wasnt doing this before but didn’t know if the springs would cause this. I can recheck the torque but it was 5lbs for the springs. Any tips? Also what are good replacement clutches? My friend has a Yoyodyne kit that needs a basket and the ball bearings. He has it on a 999 but says it fits the 996. Thanks in advance

Seems like your clutch plate stack height is too high and is dragging.

Or your clutch lever needs more travel to disengage the pressure plate.

Remove the spring opposite the broken post and see if that improves things.

Check stack height first.

Bleed clutch line and investigate for leaks at the slave or master end

Be aware that some aftermarket clutches require different length push rods which could interfere with proper function.

I've never seen any aftermarket clutch kit require a different length pushrod?

I have seen the Slave cylinder with the adapter shim included to use on pre and post 2000 bikes though.

Not looking good. Ordered a clutch kit and began disassembly and discovered so much carnage. This bike sat for years and I did the basic maintenance to get it back on the road. I swear it wasn’t going into 4th or 5th. Maybe these pictures explain why. Now I have to find an inner hub or aftermarket one. What would cause these fins to break?

Also is there supposed to be a rubberized coating under the clutch basket. Mine had one but it seemed to be breaking off into the clutch plates. It’s everywhere. Going to guess these are the rubber vibration pieces and they just melted inside there. Causing the fins to shatter. But why does that happen????

Any tips are appreciated.

Thanks

That looks like built up grease/clutch dust. I agree with you that you have some serious carnage. Wtf?
