Two gen 3 questions

[smithabusa]

Iet me look through my pictures, I had the transmission out a few months ago.
If not, I have the service manual for pics.
It's more in the shape on the 1k, as the 2017-2023 only has 3 clutch springs.

Same on gen3 busa

Yes sir, that looks like the same animal.
I wonder if it's the same part?

no different part numbers

I will say a couple of times i have stalled my bike when rolling, and attempted to just release the clutch in gear to bump start it, and it has no part in that, seems to just slip the clutch enough that it never engages enough to start.

Yeah, but I wonder if they are still the same, and the Busa version is distinquished by one number difference...and probably a higher price, lol (I'll have to check that)

That's odd, as I have roll started this '18 Gsxr1k several times, and it started just like any other bike, and in first and second gear.

I wouldn't think so

What mechanism makes the clutch slip on the 1k bikes, how does it work differently from the Busa?

Look at the above pictures, you can see how the pressure plate will rotate as it moves in and out, it moves like turning a fastener in a quarter turn, then back, vs the Gen1 and 2 Busa pressure plate which just slides directly in and out, and has that funky clutch hub nut instead, which is what gives it some play, and why they get welded for drag racing.

Yeah and welded no good for turbo hp unless adding a lockup
