Modify 2000 ZX12 inner hub?
Is it possible to modify, drilling oil holes, the 2000 ZX12 inner hub so it oils better? Or is it smarter to just upgrade? I have heard that newer years will fit the 2000 but are updated.

yes you can modify the 2000 hub, but It's to easy to just get the 2002 up .

I found the information for the flat spot mod. I just have some questions as I couldn't find pics and everyones terminology is a little different.
To cross drill the pusher shaft I measure 1.65" up from the part of the shaft that seats deapest into the motor?
I then cross drill .040 holes behind the needle bearing flat?
BEHIND meaning towards the inner motor or between the bearing and the shaft so that the oil squirts onto the needle bearing and then the clutch?

ok here you go,
the purpose is to get oil from the trans shaft to the clutch pack. Muzzy has a kit that modifies a sleeve and the hub (hard to copy without maching equipment) or you can drill the hub and do the flat spot or drill the pusher.
I had a Muzzy modified sleeve and hub in my bike when i got it. I copied the drill pattern in the hub where the clutch pack goes for dads hub, and did a flat spot to the pusher. its very hard to copy the machining by the sleeve/hub nut on the hub. hes running an MTC lock up so his pusher is different than the stock ones, so ill include a pic of how to modify a stock one too
dont grind too much off or you will have too much oil in the clutch robbing power, and it will lower the oil pressure. start with a small amount and work up untill you no longer have dry clutchs.

it is. the long one is an MTC. you need a longer one because the cover is spaced out on a lock up to make enough room for the snowflake.
the stock one and mtc are hollow, the mtc is also thinner except at the end. it reduces binding if theres any play side to side (but the bearing insert in the cover pretty much gets rid of any anyway). see how the stock one is worn by the tip of the trans shaft?
i didnt mic it, but i would start by making it 1/8 in across for the length of the green section in the pic. if you still have problems with a dry clutch grind away a bit more. i did this for a buddy at the track with a busa and had to do 2 pretty big flat spots. you may only need a small one, but go in small steps so you dont take away too much.
a lock up the way it comes from MTC:
fyi, dont set it up with that much weight lol

I got the 2002 inner hub. It has 6 holes on the bottom but no holes along the ridges as in the above pics. Would it help to add those holes as well?

Cool, thats what I did. Has anyone ever had the inner hub fail? I just ask because I see that Muzzy makes billet hubs for Suzuki but I didn't see it for the Kawi. I drilled the holes, per the pics above. I got off a couple of grooves on set of holes but other than that Ill try it out as soon as my basket gets back. Thanks for all the input.
If I never said before, this engine is in a custom sand rail that i recently built. It definately screems and I hope these mods will keep it together.

that looks like a fun toy!
ive never heard of a hub failure, but lots of guys blow up the stock basket. i think the billet piece for the zuks is just to eliminate a cusion or something. lots of guys just weld them solid. ours is allready solid
