What they say is the best way to do things when money is available.
Sometime we have to do what we can to make things work within a budget.
I would have the cases welded and put another stock trans in there.
Check it well and replace any gears with abnormal wear.
Probably fix everything for $300-400 plus your time.
Remember this is a 10 year old bike and its life is probably limited to a few more years.
That same $2000 dollars will go a long way towards the next bike. The zx14 is already here.

I'll end up staying with the 12.It's paid for.I posted a question once before about how long people held on to their bikes.For me,ten years is not that old.Look how many people regret selling a bike they once had.I'm only ten hp over stock per cylinder so reliability shouldn't be a issue even with my weight.I can't see getting another bike as I don't ride much on the street and just go for the thrill at the track.I don't need to go faster any more as I'm happy with what I have now.At 6'5" and 260 without leathers,I'll never be close to those even 50lbs less as far as times.In a way,I'm greatful for the opportunity to experience these lows.It certainly makes a great conversational piece.Oh I agree that having more track time would be cool but like women,the chase can have its fun too.Yeah,I guess I'm just a stubborn old fart.LOL

Well Pete I see a few options.
We can weld the cases, it doesn't look unrepairable, its not cracked near a shaft journal.
It looks like a piece of gear got caught between a gear and the cases and leveraged it. Bill or Alex are good aluminum TIG welders. We weld aluminum heads, blocks, manifolds everyday here. We will V it out and bolt all three cases together and do 90% of the welding and let it cool. Then disassemble and finish the last 10%. Not a problem if done right.
Option 1 get a used trans or just the gear you need. We can magnaflux all of them. And run the bike on the street. Your size and the engines added output might not be a good combo.
Option 2 is a race trans with a set of billet gears and continue to race.
I think I'd weld the cases, put a used trans in it and ride it on the street. Have some fun with it for a season or two and sell it. Maybe get a 1 or 2 year old zx14 or Busa in a year or two.

i agree. i would get the trans checked out, use whats good, replace whats broken with better stuff and get it back cut. if you are going to drag it, minumin billet 1 and 2. why have all that power and not be able to use it?
or
sell the motor and buy a stock one. stock power levels shouldnt stress it nearly as much, but you will still run into problems drag racing a stock trans eventually...
if you cant swing the billet stuff for awhile, get the cases fixed, put in a stock trans and dont race it untill you upgrade. drag racing is probly the hardest thing you can do to anything(Tim may counter that one, Im not sure)
if you are unsure of what to do, just park it for awhile. who knows, maybe santa will bring billet this yr

Since winter is coming, I'd just wait a little bit until you can afford to put the best trans in it. If you are going to keep it, do it right!

well after having my 07 season ended early with trans problems and only running a pipe and pc for hp upgrades, i decided that i was going to try and make it bullet proof....so far its taken everything i can throw at it, and i hope it continues to do so, im not going to turn down the power any time soon

Mine has the basics:
Undercut (a new gear or two)
Nitrous cut drum
New forks
Heavy duty shafts
I think that was about it...

thats what we have in dads 00, but its getting billet this winter. undecided on if we will do more than 1-2, depends on how things go this winter. might put a big wet shot to it, so that may be the deciding factor

My bike will likely see more lsr, which is a lot easier on the trans.

AA,
If money is tight weld the case and put a stock trans in it. If you can afford it spend the money on the trans. If you do put a stock trans back in it I would take it easy on the dragstrip launch or your going to break it again...

Those are Scott's gears; my trans has the full work...except still has oem gears. Mark at R&D told me "good to 250 hp".
My motor is a 1287cc mill built by Sal. Pretty much new or refurbished to better than new components from the ground up. The basics are 1287cc, cylinder head porting, and cams. On top of that, some extras...such as the trans work, cylinder studs, billet basket, falicon crank and rod work, etc. etc. etc. Nitrous? Well, the motor is certainly capable of more than natually aspirated running. 
As we all know, Sal can make these 1287's fly. I have no doubt that this one will move me down the track with authority.

There are more stock trans at the track than billet.
My 1361 with spray ran on stock trans and went 8's.

R&D keeps those in stock, or you can buy directly from Robinson, he may have other distributers, but i havent needed to look, so i dont know. Schnitz or APE may carry the first gear as its a lower ratio, but i dont know about the other gears.
the one in the pic above came from JC  i have a few pieces of that bike....
getting back to why the gear broke in the first place... maybe you air shifter wasnt adjusted proberly and it wasnt all the way into gear? that can be solved by a back cut as it will slide the rest of the way in once started(literally pulled the rest of the way)
we dont have a lot of passes on dads bike, but its shifted every time except once(fluke?). if you get a stock trans back cut, use R&D, the use smaller cutters on their machines that dont require as much material to be removed to get the back cut. leaves the gear stronger as you would expext, but it takes longer to do. give Mark a call and tell him what you have, he will able to tell you the best plan of action.

Thanks KZScott,you just answered my next question.I can't believe the gear broke from my weight and power(no different then a 14 with pipe and PC).Was wondering about the adjustment on the shifter.

The gears are much stronger in the 14 to handle increased torque. The gears in the 12 are a step down from the ZX11, from what R&D told me.
So, it would not be unreasonable to think that the gears did in fact beak due to high loading. Every shift, all of the time, is not going to be perfect. I've missed a few on the 14 with rider error/bad setup. But I don't worry about the trans blowing to pieces when it happens! I just worry about rounding off the engagement dogs. A 14 trans has NO undercut from the factory.

Pete, i put a lil better than a thousand passes at 1/4 mile routinely running high 8's, and never had a prob with my stock trans. I don't weigh all that much less than you (230)
I finally smashed the 2-6 gearset testing on the street, getting ready for a land speed race and button shifting at too low rpm under WOT.

Pete, why don't you call around to some shops...Starting with R&D, and see what they suggest on a budget?
Just a thought...

Would it be a safe bet that it is 12st and 2nd that have the highest problems?I'm just trying to figure out if I could swing a limited amount of gears, which would be the critical ones.
