Shifter shaft and clutch questions (from a car guy)

Please forgive these ignorant questions, but I don't have a bike or linkages to look at as I try to figure out some stuff. I'm installing a bare 2005 ZX-10 engine into my race car.

1. I'm getting ready to design a shifter cable and need to know which direction the shaft turns for upshifts and downshifts. In other words, when the shaft turns clockwise (when viewed from the left side of the engine), does that induce an upshift or a downshift? I know I should be able to tell on my own, but haven't been able to figure it out yet.

I should mention that I bought the engine on ebay and assume it's good, but haven't run it yet, so it could have problems if the seller was sleazy.

2. Regarding the clutch - I've replaced the clutch springs with stiffer ones, but am not confident that it has gone back together correctly. I hope it has, but would like to confirm. I can easily move the lever by hand quite a distance without much resistance, but I guess that's not really doing anything inside. Since I don't have a working bike with linkage to look at, I'm not sure where the lever is when it starts to disengage, how far it will travel or how hard it should be to move (especially with non-stock springs). I'm hoping someone can suggest ways I can work the clutch with the engine out of a bike chassis, and that will help me determine things like cable length needed to run it to the car's clutch pedal.

Let me know if you need more info or pictures for this post to make more sense. I appreciate your help.

Shifter shaft picture

Here is a picture of the shifter shaft.

I am able to find neutral and one gear, but I'm not sure if that gear is first or how to engage other gears. Seems like it should be easy, but I haven't figured it out yet ...

Spin the sprocket and shift it that will let you know if your in 1st or either it will start going through the gears.

Clutch Lever picture

And here's a picture of the clutch lever in it's normal state (clutch engaged).

My questions are:
- How far does it rotate from here before the play is taken up and the clutch springs begin to be depressed?
- How much further should it rotate to fully disengage the clutch? (or, asked differently, how close does the lever get to the cable mount?)

Thank again for any assistance.

Thanks, Kenny.

That's kinda how I've been able to tell where neutral is. I can spin the sprocket freely. When I turn the shift lever clockwise, it goes into a gear. Can I assume that's first gear?

If that's true, which direction do I go to engage 2nd - 6th?

Get it into gear from neutral. You'll be in 1st or either 2nd, spin sprocket and try going to next gear. If it doesn't go into next gear then you know it was in 1st.

Okay. I shift from neutral into a gear by turning the shaft clockwise while I spin the sprocket. (BTW, if I do the same thing from neutral yet try to turn the shifter shaft counterclockwise, it does not go into a gear.)

Okay. From that initial gear I cannot go into another gear. All I can do is return to neutral.

So, according to your test I have found first gear by turning the shifter shaft clockwise, right?

I'm still confused. Where are 2nd - 6th gears?

I have two 2005 ZX-10 engines and they both behave exactly the same.

Shifting clockwise from neutral takes you to 1st. All you have to do is spin the sprocket at the same time as you try and shift and it will go into the next gear.

Kawasaki's have positive neutral finder gear boxes so you cannot put it into 2nd until the shafts are spinning.

Also looks like his linkage is in GP shifting not normal up shifts to change gears so I think that's what your talking about RR...also your linkage does not look like it's a pure 180deg. out from the stock position to do a pure GP shifting change..maybe that is the problem as well.
