Who knows much about these clutches? I read on the Kawasaki website that they can be modified to change the amount of slippage ... I'm wondering whether anyone has done that?

2nd question (which probably should have been 1st); is there anything that can change the amount of slip? I was on track last week, and had to blip the throttle and match the revs otherwise the back wheel would lock up and bounce all over the place. I'm riding a little more agressively, sure, but I'm fairly certain it used to slip more before.
I have since changed the oil, but haven't ridden it yet. Can 'old' oil cause that?

Nothing should really change it mate,

Are you braking too much with the rear?

I've always found the stock slipper excellent


Another is maybe too much preload on the rear making the rear shock topping out harshly.

No, I'm not touching the rear brake at all, and the suspension's been well set up .... well there's always room for adjustment, and I'll certainly bring that up with my suspension guy, although I'd be surprised.
The difference happened from one ride day to the next, no suspension adjustment in between. It felt like riding a bike without slipper clutch.

I don't know about the 10 but on my old six it had 4 springs on the slipper and the race guys removed two so that it slipped more.
I have heard they are not super consistent and some guys remove them completely to overcome that problem. I've never had a problem but I'm not that fast lol

Yes have heard of this being done. Works well apparently .

When speaking to a couple of guys that race them they said that the 2011 clutch wasn't plagued with the known issues of the gen 2 and 3 clutches.

Depending on how aggressive you are with the down shift, how many gears you drop at once and at what revs you drop them at you will still get a little lock up.

One gear at a time, fairly aggressively but no different to the way I normally do it, well I didn't think so. Maybe it's just me, maybe I've grown lazy and now that I'm staring to ride it like I should I'm noticing it more. I could have sworn that it didn't lock up at all, even without any blipping ...

What about chain adjustment? Too much slack will make it slap around and induce more chatter.

I drop 2 gears no blip and just dump the clutch into turn 2 at ec, no probs. but it's an 06 model.

Nah, chain's good, just checked to be sure, although I knew it was ok 'cos I'm thorough with maintenance and adjustments
Although I'm thinking, with hard braking (I do brake hard when needed) and stuff all weight on the rear tyre - and often momentarily off the ground, there'd be next to no grip between road/tyre to induce the clutch to slip? Still getting used to the bike, I will try to keep my weight down a little more.

Yeah but when it comes back down you want it to be smooth, and if it's not, then maybe give the spring mod a go.

this is what was mentioned about the rear shock topping out.
if you brake hard and the rear lifts the shock has toped out.
i run a lot of rider sag to give the bike plenty of room to move under hard braking.
