The Hayabusa service manual was less than helpful on giving the proper instructions on how to remove the speed sensor nut that is attached to the engine sprocket shaft. Well I thought I had to use a wrench on the nut, and didn't notice the allen head bolt until too late. I broke off one of the four nubs on the speed sensor nut.
My question is - do I need to buy a new speed sensor nut or can I still use this one? I don't see the functionality of the nub I broke off but perhaps I am missing something. Thanks so much for any help, I want to get this taken care of ASAP.
