@NENDO Sorry, I don’t have a caliper. Qualitatively, the Hayabusa shaft cover is about perhaps 1-2 millimeters (QUALITATIVE) taller than the PAS ALU shaft cover. Another thing I notice is that the Hayabusa shaft cover is graduated. It’s diameter is wider towards the bottom than the top of the of the shaft cover, and I can only fit one of the sides (of course the slimmer side) into the PAS ALU Bat Top.
I have no idea how the change of shaft cover on a Hayabusa shaft could affect the actuator/spring pressure/unknown factor that affects how my lever moves.
On my Kuro VLX with my JLF assembly, I used both the Hayabusa shaft cover and PAS ALU shaft cover with the same functionality, and normal/preferred functionality (none of that tightening BS.)
The only thing I could think of now, and I don’t know if it’s an actual factor, is that perhaps the wider base of the Hayabusa shaft cover is designed to pivot optimally with the Hayabusa pivot right below it. The slimmer PAS Shaft Cover, and I’m hypothesizing other shaft covers of similar non-graduated builds, interacts with the Hayabusa shaft cover in a way that messes up my assembly. Perhaps this factor in conjunction with the weight/size/unknown factors of my PAS ALU Bat Top on top of the assembly may affect everything overall.
At this point, I don’t know anymore and my care for the matter is waning since I have resolved my issue. And I don’t have a caliper.
Thanks to everyone that responded to me and tried to help me out. It was kinda a long night.
