All good ideas come from making problems go away. Kawasaki Ninja ZX400r Shifting Arm Lever/Detent Spring Kit will just do that
I believe there needs to be a little more clarity to this product, a lot of entry riders do not know, the issues that this is designed for is for the Kawasaki Ninja ZX400r Shifting ArmLever/Detent Spring Kit which is a commuter built motorcycle the way it is set up from the factory will infact work for the daily rider, but once you have decided to take your zx400r to the track a lot of things will change.
The current shift arm has a shift paw on the end(behind the clutch basket) this engages to the shift star that is connected to the shift drum, you can see in the detailed pictures that from the factory the shift paw does not fully engage to the shift star, Spears Racing designed the Kawasaki Shifting Arm Kit Ninja ZX400r 2023> this will allow the shift paw to move closer to the middle of the shift star for a more positing engagement. Lately we are seeing companies making delrin pieces that slide of the left side of the shifter to keep the shift arm from snapping the “outer Snap Ring” and pushing the complete shift arm/rod to the right side of the engine case. This part that they are making is not doing the same as a shifting arm kit.
Spears Racing has been on the cutting edge of making new products for the little commuter style bikes for decades, most of these products come from the motorcycle being used for something other than what it was intended to be use for…RACING!!
It has been brought to our attention that so many racers have been having shifting issues with the new Kawasaki Ninja 400cc,we have heard everything from “it will not shift” to “it misses shifts” and several of the racers have had to park their motorcycle or just go home.
Look at the the Kawasaki Ninja ZX400r Shifting ArmLever/Detent Spring Kit pictures of the engagement area of the shift star and the shift arm on the OEM install, under hard shifting/racing conditions the shift arm will just slip over the end of the shift star and it will leave you missing shifts or leave you to no shifting.
