are these gears ok?
Im going to get them magnafluxed to make sure nothing is cracked, and if they arent would you just touch up the damage with a dremmel or replace?

They are pulling metal badly '' looks like 5th and 6th are only ones that aren't on c/s!
Did you notice the gear on the crank, S/B drive has had metal go thru it as well ?
This is gonna keep happening if gears aren't replaced IMO.
Have you had a failure before that caused these gears to fail or just very heavy loads on high mileage unit ?
If you look at first on c/s that's how it starts when the gear starts to pull metal it eventually ends up like 2nd.............

1-4 output are billet gears. they looked like that after the 08 season (put in winter 07 08). this bike gets no real street miles save for logged runs for tuning purposes, just drag racing.
ya the crank is done...

As a blanket "better safe than sorry" statement I'd replace all the ones with metal "missing". Even if not cracked YET they are weakened.

Scott, I'm going to give you the 200 mph racer, non-mechanic side of it.
You only live once.
You are attempting to go over 200 mph.
Bad things happen can happen if things fail at those speeds.
Consider the TOTAL cost of whatever speed you want, whatever ET you're after. Think long and hard about all the race fuel, about the nitrous refills, about the pistons, etc. Then think about all the money it costs in terms of getting to and from the track, hotels, registrations. What about routine stuff like oil and filter changes, plugs, rear tires, etc.
What I'm getting at is that in the grand scheme of things what you have isn't just some low mileage commuter. If you've gone 8s then you're not exactly a limp wristed rider. Spend the money and make sure you put your best foot forward in terms of your transmission. Don't cheap out in this particular case. Get it done right so when the time comes and you're ready you can run the best ET you can or the best MPH you can.
Maybe I should follow some of my own advice....but you get my drift.

sound advice. I have a stock trans I can rob parts from if I have to...
Ive been in contact with Mr Robinson about getting a set of OD 5th and 6th.... maybe i can get a deal if i buy a few more pieces...

Scott,
i'd replace the damaged trans gears and i'd have the crank starter gear magnafluxed. no chunks outa the crank drive gear?
As a result of similar carnage i had dings in a Marine stroker/offset crank.
Sent it to Marine for inspection/magnafluxing, and David said run it.
i ran it hard on the dyno, and at the Mile with no issues.
Ali,
I agree with thoughts, except i'm under the impression that Scott's not trying for 200mph, 1/4mi racing only.
Maybe i'm wrong and Scott will show up at Loring this year?

Karl I think Scott was kicking the idea around, hopefully he can make it out. But even if it isn't 200 mph he is certainly going over 160 mph in the 1/4....and even at those speeds bad things can happen.
You could blow the motor and just coast to a stop.
You could blow the motor and it locks up the rear wheel potentially bucking you off.
You could blow the motor and fluids can get on your tires lowsiding/highsiding you off.
And not all drag strips have tons of runoff/shutdown either unlike Loring.
I'm just trying to make sure that a potential catastrophe is avoided if at all possible. I'd feel pretty bad if I found out there was some preventable transmission problem that jeopardized his safety at speeds.
Thats all, hope you can make it to Loring Scott.
And I'm only gonna say this ONCE SCOTT! Don't get CRAZY with the spray on your FIRST PASS!!!

Ouch that sucks! Get a hold of JohnnyCheese, he might have some lightly used but good ZX-12 stuff around. Tranny shafts?, maybe pistons, but I am perty sure he has already sold cases, crank, and carrillo rods. I hope the top end does not look too bad.

I am trying to get to Loring, it just hasnt happened yet 
the drive gear is damaged. and the stater gear may be so far gone it would need a starter cart. im not sure but a lot of the teeth are only 2/3 of the way there

i think that crank has serve its life.
Cant tell if its a stocker or stroker.
If stock trash it for sure. Stroker would require a little more thought on a race engine,

Whats the game plan KZ? I don't have very many ZX-12 parts laying around anymore. Maybe a couple stock rods with low miles, couple of bearings, a handful of lightly used ss int & exh valves. Once you figure out what you are going to do post up a parts list and maybe a few of us can donate. How is the top end? I have seen complete ZX12 motors on ebay going for somewhat good prices.

Scott, if you need valve springs I should have my stockers last I checked, about 10k or so on them. If it helps you get to Loring you can have em for the cost of shipping.

it was a 4mm crank
i have a spare B motor i bought locally with a spun rod bearing, 1 piston hit the head pretty good but no signs of hitting valves
i have a crank and set of rods from a different motor
the head i got lucky with. a few bent valves and cracked guides. fixable by Jim. Im good for springs Ali, thx though. I think these are actually ok(carpenter). I wouldnt want to run stock springs with the big megacycle cams anyway.
waiting on hearing back from Bill right now about the gears

By looking at the pictures it looks like the trans. is trashed and would need to start out with a fresh one....But it might just be residual pieces of other parts stuck to the gears....
Hope for the best,good luck.....

Where your starter gear assembly is, is the engine case snapped where the bushing goes? I noticed it looked a little cocked.

If the the starter gear is still operational.
New thinking : because the clutch basket is engaged full time the inside edge of the crank gear could be dressed to save on your investment. I cant see how that would increase risk of damage if you insure smooth rotation.
I MAY have a stock 2000 crank with one bad journal in my parts bin if you are interested let me know and i'll check.
