Nice job. It autta rev quicker now.
Too bad you didnt machine of the balancer gear on the crank while you were at it. Still not too late.
Does anyone know what APE can remove from a 2000 crank? I see they offer it.

Make sure you don't remove the starter gear in the process!! I "think" I know someone that has two unusable +4.6mm cranks lying around that had that done to them.....

I wonder how much you can cut off the gear? Has anyone tried it?

Y2KZX12R this is what the crank looks like from APE and just by looking at it, it's lighter than my at 22lbs!!and it's was 25lbs! my guess is around 18 lbs to 20lbs i would say 5Lbs to 6lbs off

so.............
in the long run, (not 20 passes and boom), what is better.........
Leave it in, or take it out.........., on a bone stock motor........

Where is Doug Meyer? Of coarse, muzzys says no probs, but I dont trust them, their sales reps have lied to me before.

(sorry for the thread ressurection)
And anyone with a failure with the balancer off? (Just wondering where it would fail?)
Looking to do this with a BMW bike. Googled and this thread popped up.
Not many people doing it on motorcycles it seems...

Well, I went ahead and did it on a K1200R.
Makes a difference on the ass dyno. Have yet to take it to the track.
Buzziness gets severe from 7000-9000 rpms. Feel it primarily through the grips.
Definitely not a mod for the street (on this particular bike).
If anyone's interested, I'll let you know if I grenade the engine.
BTW, since the oiling holes on the balance shaft are open with the balancer in place, can't I just leave it open? Or should I weld it closed?
Anyone ever use some of that liquid weld(JB weld) for stuff inside the pan? Or should I just weld it?

jw,
with the balancer in place you want the holes open; with the balancer removed they need to be closed. Gotta be real careful with this mod.

Thanks for the recommendation, really. I will most likely pull them and weld them up.
But....
Is your suggestion based on real measurements or just educated suggestions?
1) How much oil can pass through the small passages in the first place?
2) How much less pass through with the balancers in place? Will this difference make a difference?
3) Should you tap and plug the oil passage in the case itself? Because if you just weld the balancer oil passage closed, I'd bet that some would leak out around the shaft and fall into the pan. There are no seals around the oil inlet side of the balancer shaft, just a tight fit.
(BTW, from an experience standpoint, I've rebuilt a zx11 with a muzzy block with ported heads. I even fuel injected the thing and fabricated my own intake manifold including making the calculations for plenum volume, intake runner size and length. Just FYI, to let you know where I'm coming from. )

I have no direct measurements of oil flow without the balancer and without the hole plugged, but i sure as shit wouldn't do anything which will defeinitely lower the oil pressure to my bearings...

And increasing the pressure and maybe flow a little by plugging the hole couldn't hurt either.
Point taken.
Thanks.

JW...Are you removing the balancer on a ZX12 ??? If so, Muzzy makes a dummy shaft. Remove the balancer and shaft, Install the block off shaft and "o"rings and your done. Been running mine for 2 seasons now...... No problems

No. It's a BMW K1200R. But suprisingly very similar engine design. Just a couple bells and whistles like knock sensors, closed loop O2. Bike itself has cassette gearbox and shaft drive (good and bad). Not a bad deal used. Guess BMW is having trouble convincing the old BMW crowd to buy this bike.
I actually made a chart of vital engine stats like bore, stroke, rod length and ratio, valve size, valve angles and they were surprisingly similar. One thing I couldn't find was camshaft data for the BMW.
Power output stock is somewhat similar but the 12 seems to respond to a pipe and fueling changes so much more than the BMW. Always been a big 12 fan. My ZX11 thirteen years ago was my first "fast" bike. (Jeez, time flies!)
Anyway, thanks for your update! Two years of street or strip riding by the way? There's no way I could ride this thing on the street with the vibration coming through the bars....

Roy, did you balance yours? I did not do it cause I was afraid of hurting something........

Nope...I did it while I had the lower case off while rebulding the tranny. It seemed like a chunk of extra weight. Muzzy didn't mention rebalancing anything when I bought their dummy plug. I notice a slight vibration with it in neutral and I rev it up to about 5500. But I can't tell the difference going down the track..... So far so good
