any tests done with a launch and shifting up thru the gears? that might be a little too much oil? hard to tell without a good simulated drag run

Have not yet, been snowing here.

Too much oil, cause it to slip?

i dont know if it would slip(maybe?), but i think it would add rotating weight and maybe rob a psi or so from other places until the pump overcame the relief valve pressure.

go to the drag strip, make a pass, drive back to pits, pull the cover.

OK, but what does "to much" oil look like? And what does "just right" look like?

Is there something different with A model and B model bikes that would make this unnecessary on say a 2003 B2? This issue is mentioned as a Gen 1 bike issue. I dont see any difference in the clutch rod or sleeve bushing, only the clutch hub part number is different from 2000 to 2003 (but physically I dont see any difference wiht an 03 set up and the pics of in this thread that would change anything. Outside of, IF I have a dry clutch this would be beneficial...

HI All
KZScott, what is the difference between stock hub and Muzzy's? Please correct me if I am wrong, Muzzy's hub is drilled through in these two little wholes?
Or does it have any more differences?
I have ZX12 2002, bought Brock's clutch springs and now I am wondering about this mod.
I have bought this hub (stock from crashed bike) and I can't see any differences at first glance.

Muzzy starts with an oem hub and does a similar process

Thanks for answer KZScott, but I still dont know what is exactly the difference betwen this hubs. I want to know this because I am going to tune my ZX to around 210HP, and the clutch is very important part in this process - in my opinion.
So what about the wholes? Maybe general dimentions are some different? Are you able to make mesures of it.
and for last please confirm, this same modyfications are you made in 2002 and Younger ZX12?

If i remember correctly, this ended up being just under 1/4 wide that was ground down. I made about 30-40 passes at the strip last year, no issues. Over 2000 miles on the street, no issues. Still on the OEM clutch which has almost 17k miles on it. No decrease in power or ET from my best guess. I had drag raced before and after, but there was other power increasing mods added, and also a drastic change in elevation, so it's hard to say exactly.

Guys Thanks for help. from begening I know what to do with the pusher, but I am asking you about the hub. As I mentioned previously, I have bought this part and I cant see the difference between my (original from other bike) and this one below. All what I am asking you regarding this item.
I read all pages of this topic, as I understand - in all your cases you "fixed" the pusher not not the hub. I have posibilities to made this hub (my friends working in kind of factory)
KZScott you drew the arrow (to the hole). I am asking you about the holes, are they drilled through? Because on my pusher they are drilled in 4mm of hub
