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

Solid breakdown of how it goes at the hit without the clutch mod. It's not fun!

Thanks man!

It's probably not going to help your stalling lol

They're definitely good for aggressive riding. Just not good when launching hard from a stand still.

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.

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 🫡🧊

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.

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!
