Reducing engine braking on a 05-06

I have heard that by removing a (what!?) from the clutch would reduce engine braking. Is it the torque limiters (1 or 2) that should be removed? Anyone here that knows? I want to be able to change gears like a retard!

I do not know enough about the '05 to tell you how to modify it to reduce engine braking.... you are likely talking about the back torque limiter, or 'slipper' clutch. These are also generically called Sprague clutches, because of how they loosen up the clutch pack when the rear wheel slows more than the engine will allow -- the friction discs 'slip' against the pressure plates and limit the 'back' (reverse) torque.
I know an ecu flash can remove it from the r6. You might want to look into going that route and whether or not that can be flashed out.

Yes I am, though my slipper clutch doesn't really feel as it slips at all. On my 4-day test in Spain I painted a couple of black lines on the ground after sloppy gear shifting, specially before turn 1 in Valencia - that one is so fast you see god during braking.
What I heard, removing one or 2 of the springs in the clutch (called torque limiters in the service manual, those three armed plates) will make the clutch slip a lot easier.
I think. Looking for some confirmation that I've got it right and don't wreck my clutch.
I'm no expert but I think it would be easier to adjust the engine braking via the ECU. What you are talking about is only adjusting the slipper, as I understand it. You can also check the KIT racing manual for mods they specify.

Yes but i find no other way to adjust the slipper, i might just be stupid though.
Adjusting via ECU is not an option since i dont have any pc/bazzaz etc. Tried to download the racing manual but the link is dead.

Adjusting the slipper still doesn't change engine braking though.

Bazzaz/PCV have nothing to do with the ECU as well those are piggy back units, you will need to flash your ECU or get a KIT ecu to adjust engine braking.

The only other option I can think of is adjust your riding style and start blipping the throttle, or purchase a aftermarket slipper, but you will find a flash is the cheaper option and you can adjust a few other things at the same time.
This is the first link to come up when I googled 05 zx6r kit manual....

I know about blipping the throttle, and i do as Well as i can, problem is when you pass 3 people coming into a turn while braking from 230 to 60kph, and being passed at the same time, while going from 6th to 1st gear, at least for me, something will be sloppy, and since braking, not pushing anyone else off the track, not being pushed of the track, turning, not torpedoing someone else and getting at least close to a good line through the turn all is more important to me then a perfect downshift, the shifting part will be sloppy and the rear wheel slides all over the place - which I don't enjoy. So I would like my slipper clutch to act like one too. I know that in superstock class, they may not use aftermarket clutch so they pull something out of the clutch to get the same effect. At the same time, engine braking is almost eliminated since the clutch just slips if the rear wheel tries to turn the engine over.

I agree blipping isn't always the easiest solution and I understand the value of reduced engine braking and why it helps and where, I was just listing suggestions to try and help you.
Sorry I'm on my phone so I guess I can't link the page properly, feel free to google 05 kit manual the first link from factory pro worked for me.

I just found the problem - double http://!
Thanks, I will take a look tonight when I get home to my computer :)
Only found dead links when I tried yesterday, thanks for trying to help :)
Sorry my fault, I see that now, hope it helps, I think what they describe for the clutch is what you are looking for
