MUST HAVE Hayabusa Clutch Mod Back Torque Limiter AKA Slipper Cutch Delete

- If you are planning on bringing your stock clutch Hayabusa to the drag strip, or somewhere else you’ll be launching hard from a stop, this modification is a MUST! With your stock clutch, you WILL experience Banging, Chatter, and Bucking at launch. Those issues left me wondering “What am I doing wrong!?” Well for once it wasn’t me, but a mechanism in the clutch referred to as a Back Torque Limiter and more commonly known as a Slipper Clutch. This device prevents sliding the rear tire or over-revving the engine during aggressive downshifting. But at the drag strip it causes inconsistency and frustration. Though there is more than one solution for this mod I went with Brock’s Performance Clutch Mod. (Not sponsored! Just my recommendation). I’ll show you how it's done!

Nice Job. Very easy to listen..AND LEARN... Nice job again bud...
Thank you for posting this videos!
keep the busa vids coming, how about a throttle bodies balancing vid cheers.thanks for sharing
Have done this myself. Really nice part. The bucking is an interesting thing. The btl😮 increases spring pressure as you increase torque transfer. As you try to ease the clutch out and tq transfer increases, This increase in spring pressure tries to pull the clutch lever out from the bars faster than you are releasing it. your muscles react and pull the clutch lever in a little, tq transfer drops, spring pressure drops, then you are back to the start.. this happens very very quickly and causes the bucking and shuddering.
Solid breakdown of how it goes at the hit without the clutch mod. It's not fun!
Awesome Matt《☆》Nice Mod Tutorial Brother👍🏾🤳Brocks makes good stuff. I've stalled my Busa out several times just trying to leave traffic lights in a hurry when the light turns green & I'm not paying attention🚦😁I don't race but I might consider this Mod for Street use🙏🏻Good Luck at the Track✌😎☮
Thanks man!
It's probably not going to help your stalling lol
I L9VE MY SLIPPER CLUTCH
They're definitely good for aggressive riding. Just not good when launching hard from a stand still.
Hi master
İ need help for lambda switch
How can i fix
Link for shop
Hey man how is the clutch mod working out for you ? did it reduce the noise and has it made any noticeable differences in normal riding just curious, my clutch makes some noise,when i pull in the clutch lever a tad the noise is gone that is how i know that my clutch is worn a bit , looking to fix that issue...
Sorry for late reply. I fell off of the content creation on here. But the clutch mod fixed my launching issues. Smooth sailing while launching at +4000RPM from a stand still. It will drag the rear tire on early down shifts with this installed though. She's a drag bike only now though, so I'm not shifting up and down really. Just up in a line and then down shifting slowly as RPM drops low as I slow down in the shutdown.
Why would this cause launching issues if the slipper only actions in one direction (deceleration)?
Good question!
Because the basket is driven in one direction so regardless of whether you’re on the power or decelerating it’s going to slip if you take the pressure off the springs and off the clutch plates.
When launching from a stand still and definitely while doing it with increased RPM before launch, it jars the system. If you look at the teeth on the drive and at the receiver of the slipper mechanism, it does have slope on one side, so you don't feel it on normal accel, but when force pushes opposite on decel, the push on the sloped end pushes in on the slipper receiver part that is attached to the springs that press in the pressure plate, lessening the force of the springs on the pressureplate squeezing the clutch pack and allows the clutch to slip.
But you will also note with the teeth and receiver of the slipper mechanism, there is quite a bit of slop there. I'm not 100% sure why this happens but the shock caused the springs springs to release pressure and then squeeze, and doing so back and forth, when the drive teeth shock the receiver on a hard standing launch. This mod removes this mechanism so there is no movement of the hub that holds the springs to the pressure plate aside from only its rotation with the engine.
This mod really is for drag racing. And this is not some B.S. product. I absolutely experienced this launching issue myself, and this mod fixed it completely and by itself.
I have one note to make to this install however. The spring spacers that add spring tension to the pressure plate are really only necessary with an engine with more power than stock. With my stock engine I find better clutch feel and no unessesary slip of the clutch when wide open down the track.
8:14 what size socket was that bro?
I should have mentioned it in the vid, my bad! It is a 30mm
Naw it’s enough going on as is😂 appreciate you for the knowledge and time 🫡🧊
Here’s a tip for ya. . . Be sure to blow your nose right BEFORE filming a video… pretty awful having to listen to you sniff every 10 secs 😂
It was freezing out! Lol, And barely warmer with the propane heater in the shop I had to turn off during takes to avoid the noise. Couldn't get the runny nose to stop. Plus I was in the zone. So sent it!
