Eh..I dont see any oil pressure pumping oil through those holes....I thought the holes in those hubs (and the muzzy hub) were for oil RETURN...so the hub doesnt fill up....not for providing oil to the plates themselves. Idea being that the cross drilled puller and or flat sided puller would squirt oil into the inner part of the hub...and the holes would allow the hub to fling oil all over the plates/fibers via centrifugal force.

Hopefully we can take something out of these above mentioned post's.Rick (Crotch Rocket)has a clutch set up that seems to last longer than everyone else's.The main difference being the use of an OEM 2002 later clutch hub and 2002 springs....NOT THE MUZZY MODIFIED HUB !!!!Rick and I are basically using an OEM set up with a billet basket with no other modifications to the rod/pusher.I can't explain how or why Rick's set up is better but it's working for me.Everyone is buying clutch parts here,just try a set up that is proven by not 1 but 2 bikes with 2 different gearing/wheelbase set ups,riders who dont have the same skill level nor do they weigh the same.What more proof do we need???I was a little skeptical at 1st but Rick sold me on the set up.You guys an gals saw us at the Grudge Race not touch the bikes except for putting gas in them and oiling the chains! Every time I go to a track rental or MIR seminar its always 3 passes back to back then a 1/2 hr cool down.After the 3 rd pass the clutch definitely feels softer but after a cool down it seems ok...I put 18 passes on my bike at the Grudge Race and have made as many as 25 at an MIR seminar without touching it.Also Rick had raced my bike also he has gone 9:58@145 on that bike!!Try it out!

I just looked at the spare 00 Muzzy hub I have. Only difference I see is there are no square holes and judging by the pic osti posted.... the solution would be to drill holes on both sides of the clutch spring threads like the 02 hub above. The oil supply is still coming from the middle splined area though which limits the oil flow unless you tap into the middle where the puller shaft goes.
I also noticed that because of the way the hub is cast ... the only way to ensure oil flow to the inner most fibers/steels is to drill some more holes at an angle towards the back.
I will try to finish this mod this week and see how it works.

How about SIMPLY Cross drilling the PUSHER.
This will give a nice dual spray of oil INSIDE the Hub.
Since the Pusher is hollow, metered oil from the Input Shaft will flow into it.
DONE!

Being that I don't have the clutches out of the 12 and We have the Muzzy basket, will the 02 OEM hub work with the Muzzy basket or is the hub design to work with the OEM 02 and up basket? Confused? Our 12 is the 00 model.

CR;
Ever since the bike (00') had 9,800 mi. on it. My Mechanic (Cycle Werks, Tempe AZ) and I "Hopped" up the Clutch by having a Falicon Billet Basket Installed, Heavy Duty Springs(Schnitz), Drilled the stock Hub to let oil pass from the inside. We examined the "Pusher" and found out (with a pen) how deep the HOLLOW portion was. We saw that it was deep enough to send oil INSIDE the Hub from the Input Shaft. All we had to do was have it cross drilled .040 by way of EMD.
20,000 miles later AND a very healthy 1270 kit installed (at 13,550). I have NEVER had ONE Clutch Issue!!

I posted this in the ZX12R Zone "What is the 12 for Anyway's" Thread.....
I also own a 2000 GREEN 12. It has been the "Do All" bike. I have done everything from Touring (200-400 mi. VERY comfy), Drag Racing (9.66 @ 150 mph), Canyon Carving, Top Speed Runs (196 mph STOCK w/ muzzy pipe and PCIII, Arizona Desert at 2,200 ft. mean elevation), Track Days (1:52-1:54 lap times at AMP's 2.28 mile course), 2nd Gear (NO CLUTCH) power wheelies, grab third and hold as long as you want! Let's not forget the SUPER stability of this ride at triple digit speeds (from 140-160 mph) through mountain passes (hwy 87 from Fountain Hills to Payson AZ.)!
When I do Dragrace, which happens to be 3-5 times a year, I can run some upper 1.60's 60 ft.Times. My midtrack times have been in the 6.3's to 6.4's @ 119.93 mph. Not the Greatest, but not too bad either.
I weigh 225 in full gear......
This is NOT extreme. However, I do NOT have any HINT of blueing on my Drive Plates.

I have the solution to the overheating clutch issue.
Just read my posts.......
I'm not saying it doesn't work... however, given your riding, your clutch doesn't get abused as much as someone who drag races alot more than that (I go 3-5 times, a MONTH). So I really can't see how you can say that this modification is THE solution to all these overheating clutch problems, when it really hasn't been proven so.
Although I might just try it and see for myself.

If you want Oil in the Clutch to help cool it, Do the Mod.
IT WORKS!

Im sorry..but cutting high 1.60 60ft times is NOT dragracing imho. If you were cutting consistant 1.50s like CrotchRocket.... Id head your advice.
My 00 went 10,000 miles (and 30 passes at the dragstrip) with a clutch incorrectly installed by the dealer handlng the recall.
Does that mean its a solution too?

You can lead a horse to water but you can not make him drink.............
Logical thinkers will understand how this SIMPLE mod will allow the clutch plates to get more oil to help cool it.
I'm sure CR will try this mod and give us GREAT feedback. (Since I'm soooo slow)

No one said you were slow. Just that you don't drag race enough, or run fast enough to really prove that this is the solution to everyone's problem.

He's talking about cross drilling the pusher/puller shaft, not the hub.

Obviously you still have to "properly" drill your HUB to allow oil to get to your plates.
There are Members out there with Muzzy Clutch set up's who still notice that the hub and plates are still on the dry side. The cross drilled "pusher" solves this easily.

long lasting clutches
I would agree with the comments about Muzzy parts and dry plates. I have noticed this with my billet hub and Muzzy inner etc. Bone dry!

Entropy; I have stated repeatedly where and how to drill the pusher shaft. Apparently, it has fallen on deaf eyes.
