Karl, I sent Jim a pm 
Sal, sent me some of your weather! lol
Woppi, did you have any porting done or just the seats cut? what kind of hp gains did you get?
Im thinking about doing a little port clean up myself, nothing major, no reshaping, just getting rid of the bumps and such. ill get a few pics when im ready to try it, and ask some specific questions, the intake boots dont quite line up with the head....

what i know ---- at my zx12 head --- the little austrian company = cut the seats + modified the inlet + outlet port !!! + did the valve job ---- mount adj. cam sprocket ------ with this modified head, the engine has much better draft !!!!!!!!! belief me !!!
i would do that once more !!!
i know - money - money - money --- always the same problem ----sh......money!
but think about ? your last shirt has NO pocket !!

sounds good woppi the more pics of modified stuff i see the better!
im going to get a few pics of my head tonight, i made a valve spring compressor, and took out all the valves, lots of carbon build up that needs to GO!  Sal was definatly right about needing new valve seals. theres carbon on the intake side...
Im getting pretty tempted to get out the dremmel with a sanding drum:P, spent some time looking thru Jims Y2KZX14R build thread
more in a bit, im off to the shop!

why buy one when you can just put one together? :P
EX
IN (carbon build up, leaky valve seals grrrr)
I couldnt help it, once i started cleaning off carbon, i got out the dremmel lol.
just getting started....
more evidence of leaking seals...
about 95% done on this one, like i said, nothing major, just a clean up
damn this stuff takes a long time lol. time to call it a night:P

ok, i just couldnt leave it at that lol. the ID of the crushed exhaust gasket matches up with the ID of my Muzzy pipe, so that means the port is a lot narrower than it has to be. i talked it over with my racer uncle and looked at Jims 1375 build pics again, and just had to widen the ex port to match the pipe
now im 95% done this one:P

I will definatly keep you posted as the build goes on. Im learning a lot, and it actually looks like i might kinda know what im doing :P its taken a few hrs to get that port the way it is, but the rest should go a bit faster as i have now mastered my dremmel technique . i see now why someone would charge a grand to port a head. I think what im doing should be worth 7-8 hp (sound right??) its just taking time to do, so its pretty much free HP  . a few hp here, a few there, they all add up..... to FUN
definatly going to break the 150 mark in the 1/4 NA this yr maybe mid 160s if i ever get around to hooking up a 40 shot....

Woppi, its the low first gear made by Robinson Industries. http://www.robinsonindustriesinc.com/html/kawasaki.html
it changes the first gear ratio from 2.42 to 2.50 to get better launches. I think you can get it directly from Bill for $220, or from ape or schnitz for a bit more.
Now that i have the first gear, im going to send my trans to Bill to get the gear dogs re cut (not a race cut, just getting them fixed) and getting them matched up to the billet gears. Im buying 2-4 from him too, gotta send him another email to see what exactly he needs me to send.....

my goal was to drop a second off of my best time, but now realistically i think with the proper setup i can get half that on motor, and maybe tick off a couple more tenths with a small dry shot if the budget allows for one. hitting 8.99 on motor is now the goal . and i want it to be able to take anything i can throw at it later on. (so i gotta make the trans billet pr....er bullet proof:P)
with the 1-4 output gears replaced with the billet ones, that takes care of all the weak window areas some guys say are just a ticking time bomb. the 5th and 6th output gears dont have that problem due to the design (as you have seen several times im sure Karl )
now, off to the shop i go, i have a chain guard to make for a guy, and lots of head work to go

snow!
its gonna be 80F in Houston tomorrow...
I am very happy with Carpenter springs.
some folks say you don't need stout seat pressure and i respect their opinion.
BUT another group of very successful builders/racers say seat pressure helps longevity at no sig cost in hp. I am following their advice,and am glad you are too.
I still think you should send yr head to Jim for seats; sig hp improvement avail in correctly cutting the seats.

80F! its 5 am here and its about 18F! lol
sig hp increase = roughly how many % Karl? (just from the special seat cut). its nice to make as much as possible all motor, but a dry kit has such a bang for the buck....trying to weigh the pros and cons of everything. i can only put so much into the project this winter before i have to sell a kidney:P

good pics woppi thx
any of the exhaust side?
so its ok to cut the in valve guides? i allways heard it was bad to cut them flush with the port as it lets stuff heat up and wear out faster(for that little bit of extra flow it wasnt worth it), but maybe that was just talking about the ex guides? hmmmm more questions for Jim....
