Posted By XFBO on R6Messagenet Well, I was in disbelief that this forum didnt have one of these when I was looking for one so I decided to write one up myself. I took some pics too but will incorporate those images later one. Hope you guys find this helpful!!! Yoyo Slipper Clutch Install for the ‘03+ R6 Parts the Yoyo kit replaces: - Pressure plate - Clutch boss (new piece is a 2 part design) - Nut and tabbed washer - 6 bolts/buckets that hold the PP to the CB. Uninstall 1- Place bike on rear stand.
(sidestand will work too) 2- Unscrew and remove clutch cover bolts. 3- Loosen clutch cable and detach it from the little arm that’s attached to the cover. 4- This little arm needs to be rotated counterclockwise (looking downward) and face rearward to make removal of cover easier. 5- Either remove (may make things easier) or pull some slack in the hose that runs from the radiator to the water pump.
The Yoyodyne back torque limiting clutch, or slipper clutch as it’s commonly called, is a clutch that uses a set of 1 way ramps, ball bearings, and springs pressed against the clutch boss to allow the clutch to engage when torque is applied in the drive direction, but allows the clutch boss to ride on the ball bearings up the ramps and against the springs to separate the clutch when enough.
6- With a screwdriver try to knock the cover loose carefully! (Tip- I actually found it easier to use a long solid rod snaking it through near the shock and tapping it with a mallet on one of the tabs.) 7- Once the side cover is removed, you can now loosen all six bolts and remove the pressure plate. 8- Now take out all friction AND clutch plates, trying to keep things in the same order/direction. This might be a good time to inspect them; I found TWO friction plates cracked. Note: The last two friction plates are different from the others, don’t mix them up.
Also the FINAL plate is a clutch plate (which is.25MM thicker than the rest of the clutch plates) place this one on the side, you won’t be using it. One final note about the clutch plates, take notice to how you put them back in, each plate has a rounded/smooth side and the other is brushed and has a sharp corner (just like a washer).

These plates MUST face the same direction, either inwards or outwards but they must be the same. 9- Before loosening the center nut there is a tab that must be bent up, find it, and then pry it up with a screwdriver. 10- If you have a clutch holder tool great, if not, an impact wrench will work. 11- Remove clutch boss.
Reinstall 12- Sit new clutch boss on table. 13- Make sure all six loose bearings are in place in their pockets. 14- Place the geared sprocket looking thing in place being careful not to knock any of the bearing loose. 15- Temporarily place two compression springs two new spring buckets & two new screws (opposite ends of each other) and tighten them up snug to keep these two parts tight.
(This keeps the bearings from falling out of their pockets as you’re putting it in place inside the motor. You’ll see what I’m talking about once you get going) 16- Make sure the thrust plate in place on the spline, mine was stuck to the back of the clutch boss.
17- Place this new Yoyo clutch boss in position inside the motor. 18- Place the conical or cupped washer in next, you want the cone facing inwards. 19- Next is the star like washer, be sure the legs fit into their proper place. 20- Now place a dab of Loctite on the threads and finally screw the nut in place hand tight. 21- Again if you have the clutch holder tool great but some of us aren’t that lucky so I just used the impact wrench again.
Be sure to give it a good couple of zaps cuz just when I thought she was on tight, I marked the spline and nut and gave it another zap and she still tightened up a bit. (be sure check torq setting on Yoyo instructions) 22- You can now remove those two compression springs.
23- Onto the plates, as mentioned above, the last plate that came out of the motor is the thickest clutch plate, do NOT reinstall this clutch plate. 24- You want to start with one of the two friction plates I told you is different from the rest. If you look carefully at the tabs on all eight friction plates you will see only two tabs are NOT flared, another words they are thinner than the other six plates. These two thinner friction plates go in first. Note: Friction plates and clutch plates ALWAYS alternate, at no time should either be side x side. 25- Remember to install the clutch plates in the SAME direction.
26- Now put the new pressure plate into place, put all six compression springs, buckets and screws in. Tighten in crisscross pattern. (be sure check torq setting on Yoyo instructions) 27- Reinstall cover and clutch cable. Some people will tell you to dump the oil before the install, I think it’s a lot smarter doing it AFTER the install just in case any contaminates got in during the install. Hope this helps anyone wanting to take this on themselves. Lastly, I am NOT a professional mechanic so obviously use these instructions at your own risk!!!! (unfortunate than one needs to throw in a disclaimer these days.).
I put the money on the yoyodyne slipper hoping for less engine braking and more stability. Well, it has proved to be a great investment, but from the beginning I could not find a good how to install thread to save my life. So, while I was installing this work of beauty I took a few shots. So, enjoy and don't waste your money take it to a shop for installation if you have an impact wrench and good tools. Note: You will need a partner to hold the rear brake if you do not have a clutch holder. I think it would have taken less time if I had vested in a clutch holder. But, you will only need it to reinstall the new slipper hub.
Dump the oil 2. Remove the right side lower cowling; as well as the little black wire cover above the cowling. Remove oil cap for a better grip when removing the clutch cover. Now, remove the clutch cable cover and then the clutch cable. Then, remove all of the clutch cover bolts in a diagonal order.
Remove the clutch cover while twisting the clutch actuator. Get your ratchet set and remove the pressure plate bolts and springs. You should now see the clutch hub nut in the center. This is the time when you need an impact wrench, because I hear its almost impossible with a breaker bar. When this is removed you should be able to slid the hub out with all the steels and fibers intake.So easy. This is what you end up with after the original guts are out Now for your new yoyodyne clutch: 1.
Place the spacer that was under the old hub back in its original position.very important. Check the new slipper hub to make sure that the small steel balls are still intact. Then screw the spring back on to install the hub without losing the balls in the engine.
Once you have the hub on, place the new spacer on first with the round end up. Next, place the spider spring into its grooves in the slipper hub. Now, put alittle loctite blue on the new nut provided and tighten. Now, remove the springs so that you have room to torque the nut to 110 nm. Really, you are done at this point but there is one more very important thing to know before replacing the fibers and steels.
The last fiber is thinner and very different from the others. There are two springs to replace along with that specific fiber. You will have to change the order of the last two fibers to insure that the springs don't get stuck in the clutch when it slips. Switch the position of the last two fibers. Now, you can replace all of the other steels and fibers the same way the came in. This swap will not hurt the way the clutch feels or shifts. Place the new slipper pressure plate on with the old pressure plate puller and reinstall the springs with the new slipper spring retainers provided (torque 8-10 nm).
Place the clutch cover back on, reinstall bolts (one bolt needs loctite located on the right directly above the timing cover 12 nm) the remaining bolts 10 nm. Align the two dots on the cover and actuator. Your going to have to play with this alittle.so, be patient. Adjust your clutch lever and you should be slippin. I noticed that the clutch lever has a funny feel to it. I researched this non issue.its normal.
The clutch is slippin and you will feel it in the lever.no problem. I am a hardcore street rider.I know its crazy, but I love the newness of the next corner riding thru the mountains. I needed a slipper to keep me focus on what is ahead and not wasting time waiting for my bike to settle down when I bang down the gears. R u new to the R1? I rode 100 miles today with the wife from 25 mph to 125 mph in second gear, maybe 3rd. I do not bang through the gears at on the R1, too much torque and power to need to really good luck with the slipper i am sure there are some here to help. Trust me guys, when you try the r1 with a slipper you wont be going back the the conventional engine break method.
It doesnt totally remove the braking but it made a night and day difference. I have been riding for some time now; and I have only ridden r1's. I love the bike, but there was room for improvement with the 2004. The problem with the 2004-2006 is when you set up for a corner the back end will wiggle or hop; thus, you spend more time getting the bike together then turning. Now I am focus on the turn only and not my bike. I like the back end coming out alittle, but I think you would agree that it is safer without the kick.

OH, so this is a track bike. I was thinking you were hammering the roads with this bike and somehow needing a slipper.
I have only been pounding bikes on the street for 22 years and have never needed a slipper once sorry i misunderstood your intentions. This is a street bike. I just dont get the same feeling from the track that I get from the streets. People are out there adding crazy horsepower to there bikes.do you have a problem with that mrgrn, because i have mentioned the slipper and you seem to have a problem with the idea. I rather spend my money on traction over power (the bike already has enough for the street stock). No, just confused as to how you need a slipper to settle the rear end of a bike on the street i am all for mods and don't make excuses as to why i need them but maybe you need a smaller bike if you NEED a slipper on the street to settle your bike, sounds like you are pushing the limit on public streets and a slipper is not the right course of action, slowing down is. I run the same slipper clutch, under a different name, but the exact same one.
I used to think it was a waste of money but I finally did it and I will probably have one on every bike I will be buying in the future. Most top end superbike comes from the factory with one, regardless of engine size. The benefits have been discussed countless times before but I guess it boils down to how you ride. I am a very aggressive 'street' rider but only in the unpopulated twisties area. I don't care to scream my bike down neighborhoods and city streets with potential hazards everywhere Some people have a use for the back torque limiting clutch and some people don't. I think it is a great tool Just my.02 cents.
