No, mine is a touch higher. Around 14:1, but I don't spray like that!!!!! Plus my stuff is all just off the shelf junk, I'm cheap!
My set up when I ran ran 210.xxxx:
C-16
8 deg out
~205-210HP + 70 shot (68HP) on progressive 20% - 100% over 2 seconds (Hope it keeps the bearings happy)
255lbs Butt Naked!
Most recent tune up
C-16
12 deg out
~200-202HP + 120 shot (~100HP) same as above.
But the Moon was not aligned for me that day .

I hardly consider your coated SS valves "junk". well... maybe the nitrous/plasma torched ones... but not when they were new!
its allways something, you have the perfect setup, then the moon or mars fukks of and leaves you high and dry :P
I put a lot of time into doing research about potential hot spots, and then tried to fix any that I could. my pistons got worked over, as did the combustion chambers. all sharp edges are pretty much gone. the only thing really left is the plugs, but we got that one figured out for next season 
wanna post up some piston and combustion chamber pics? since your head is being worked on you might aswell get rid of the hot spots right? it lowers compression a bit, but you have lots if you are spraying that much right? are you putting another set of the "1270" pistons back in it?
(these pics were in my first build thread, but it was so long im sure parts of it may have been missed)
this is an off the shelf 86mm JE "1287" piston. note the thin strip of material by the valve pocket. IMO thats gotta go in a nitrous motor(or so smarter guys would have me believe)
this is after some dremmel work and hand sanding of all the edges and corners
the combustion chambers were opened up and matched to the size of the new headgasket. this unshrouds the valve, picking up flow at low lift, lowers CR a bit of course and removes the corner.
i used a marker to show the new bore size
went to work with the dremmel
Ive been thinking about bumping compression up to run stronger on motor, but I think Ill keep it basically the same(12.5:1CR) and just up the jets for next season. I like running pump gas for the 1/4 but it will get c16 for lsr. gotta flow all my jets now....just so i know they are the same. I have 20s 24s and 28s the 28s are stainless so Im hoping they should be pretty bang on. not sure about the old brass ones i had been using though. the lsr guys have me all paranoid:P

Its gonna be a real tight fit with the extra "big ass" plugs from the ign module though. I have 2 nitrous solenoids in that area now! 
one question. Did you have the Rev-Xtend feature working? theres an email here you printed from Dusty @ dynojet showing a code and a 13500 rev limit.
"theres an email here you printed from Dusty @ dynojet showing a code and a 13500 rev limit."
dang! where was that tucked in? I looked high & low for that email before i sent the box.
I don't remember if i ever applied the extended rev limit. I only had the unit installed once for some experiment or other.
I bought it thinking about experiments trimming indiv cyls, but never did em.
I pulled it when it SEEMED that i couldn't get it to lean out the impact of big injectors, even sent it to DJ for "repair".
Turned out there was nothing wrong with it, but i had it set up to map indiv cyls, and was changing the map on only one cyl. dumb-ass me.

folded up neatly in half with the rest of the papers 3 pages stapled together. dated 02/06/2007
Well if this code works, Im not going to bother getting my ecu hacked and reflashed. I really only care about the rev limit for now. 13500 is "kinda" high though lol I was thinking 12500 maybe 12700. I wonder if theres a code for a slightly lower rpm? if not Ill just pull as much timing as possible starting at 12750 and I wonder if I should max out the injectors or shut them off?
have you played with the cylinder trim feature with the pc3r?

it says its sensor safe. its the permatex ultra copper stuff. just incase i would run it awhile to make sure any exposed goop either gets burned or coated lightly in carbon before putting the o2 sensor in. it may make a diff or it may just make me think it makes a diff

I made a hose/end for the leakdown and its not good. numbers are probly plus or minus 1%
1: 93% 2: 3.5% 3: 2.5% 4: 3.5%
the inside ex valve on #1 is leaking badly. going to borrow a can degree kit to make sure my adjustable sprockets stayed in place then Ill pull the head to look at the damage. maybe theres just something stuck in the valve seat, but im guessing i melted it when i put the bigger jet in the dry kit. (dont go by the dynotune chart or you will be running double the hp you think you are)
i think i found the "tick" 
Im happy with the other numbers tho, the motor has sat since sept, and temp was about 10C /50F

havent been working on the bike, but Ive moved forward in my nitrous plans. Im going to put the dry kit on dads bike and just run the wet kit with a Schnitz 2 dial progressive controller. I just bought a second hand one from schrader13 on psychobike. if anyone is looking for a new one pm Daniel London (Goldenchild) as he has new ones for the best price Ive seen going. hes a dealer of MTC and a great guy to deal with.
im thinking of trying somewhere around 100-120 hp and i should be able to start spraying in first gear with the controller and suspension upgrades. new goal: 8.50 @170

Update. I decided to go ahead and pull the head and just recheck cam timing when it goes back together. no melted parts! It did have a shim in crooked and that was holding the valve open during the leakdown, and it caused the piston to hit the valve. I dont think any major damage occured though. one other shim was a little banged up even though it was in place. it looks like that valve made a little contact with the piston at one time or another, but much less noticable as the other one. strangely enough I found no signs of the plugs hitting the pistons. the shiny spots on the plugs must have just been from the spark?? what i did find was shiny spots on the pistons in the quench area (ex side only) that appeared to have hit the head at one point in time. since quench was fine im assuming it was from the pistons rocking in the bore when i hit the rev limiter a few times.. opps
im going to clean the head up, pull the valves and see what that seat looks like. going to have the rods resized with new bearing and nuts and bolts so the bottom end will continue to hold up under the abuse of nitrous. a slight increase in quench would be a side effect if i leave everything else the same, might help if i hit the limiter again lol. there were no apparent headgasket issues which is great considering its a 3mill
some pics.
i knew something was wrong as soon as i saw this
messed up shim
im suprised some assembly lube stuck around after a full season
the shim from the other valve that hit the piston a few times on #4 pic didnt really turn out, but the edge was a little messed up
this one came out a bit fuzzy too, ill get more...

my limited info:
keeps stuff cooler by creating a barrier, think wrapped header. cooler pistons/ combustion chambers are more efficient. keeps oil cooler too. prevents detonation...
0.002 to 0.003'' i think
about $50 a piston?

i don't think the shim was yr issue, a collet is unseated...
you are a lucky, LUCKY man that both collets didn't jump and let yr valve hit yr piston real hard.
what seat pressure are you running? Are yr springs good?
I just pulled down a head with 10 trips to the dyno (spinning up to 12K )and 2 Mile events.
Springs were brand new in Aug, seat pressure dropped from 67 in Aug to 54# now and it had a bad lleakdown after the dyno last weekend.

I assumed it became unseated after the shim jumped half out and the valve hit the piston... you think it was the collet unseating that was the root of the problem?
the bike was actually running like this... I even drove it on the trailer and started it multiple times trying to fix the tick by sealing the header to the head better...
carpenter springs. supposed to be 65 pounds seat pressure. one season on them 11600 rpm rev limiter, 2 stock IN cams, nothing huge. a few break in miles on the road and then 1/4 mile blasts. maybe 6 wknds total. my springs wouldnt be worn out that fast would they?

Did you measure the seat pressure or assume it?
Measure it now to see what it is.
I don't know which happened 1st: collet unseating or shim getting sidewise; kinda like chicken & egg, eh?
When you put the head together do you assure all collets are seated?
I always put a fat shim in place then with a drift, tap-tap-tap it w/ a hammer to make double sure all collets are securely seated.
Yep, this is another one of entropy's "learned the hard way" practices.
Good mechanics don't have to do these checks.
I do

I assumed seat pressure since they were guaranteed to be 65 pounds.
bathroom scales and drill press?
I thought shim first because of the other one that was dinged up (as was the corresponding piston a bit)but the collets were in place
I didnt tap them, but i have very good vision(I can read the "dotted line" you sign on the back of a check ) and they looked like they were in(i had to redo a few i didnt get first try), ill be tapping from now on though just to be sure. my uncle told me about the same trick after i had the motor running....his seat pressure was something like 400 pounds tho lol(vette)

yep, bathroom scales, drill press and a lil jiggery-pokery and you can get reproducible results.
See what seat pressure you have now.
BTW: assume nothing...

oil analysis need a base line
so after an engine is broken in........................take a sample
even if you dont send it in
next time send in both samples
on a race engine not very much help.........youd probably do a tear & inspection
anything apparent would be caught then on that inspection
reading an engine is crucial........should be done on a consistent basis
so many miles or so any passes down the strip
wet nitous is like playin with nitro glycerin................very unpredictable
if you inconsistent ignition for whatever reason
your plans are all awry !!!!!!
a mixture going into a cylinder at 12 to 1........you have a miss fire
that cylinder gets WET !!!!!!
no way for you or god to tell what it is when you finally get spark at 125mph
at 10000rpm under load
more than likely it aint good & will show up later
so any miss steps with fuel delivery or pressures with gas in the injectors
or temps & pressures with NOS are DETRIMENTAL
you can figure something is hurt
so you more than anything want those systems very consistent or bullet proof
whats that orange stuff around your ports ?????

looking at some of your photos
i have several NO BS questions
do you ride on the street
it would appear all of your cylinders are firing differently
no less do you or did you at teardown do a compression or leak down test
very important
way toooooooo much of crap deposits on your valves foran all drag engine
if you are "booty" crusin around hooters you are wilting your rings
coating your pistons wont help much drag racing
they rarely get that hot for the minute your engine is fired up
a " Molybdenum" coat on the skirts will benefit more in an all drag engine
if tthe orange stuff in on the exhaust ports........really shoudnt be necessary
if they are that loose in the ports ......................more than likely reversion problems
now on the photos...........................& IM REALLY not RAGGIN ON YOU
I DONT KNOW HOW YOU CAN GET 3 OUT OF THE 4 HOLES OF THE HEAD OR THE BLOCK ???????? Vincent really was the best at takin great photos
yet what i really want you to see [alth i cant see them all]
are the many different colors of the valves...............................no less representing
the many different TEMPS & possibly Oil
nest time b4 the anxious rush to install the hyped ^ glorified perf parts gauranteed
to bring you glory ? ? ? ? ? ? read your engine properly ! !! ! ! ! ! ! !!
the adjustments you make.......or you can correct will actually give you your Performance GAIN
i think i saw someone mention the valve seats were phat
with serdi 5 angle valve jobs.........DO IT......the ONLY way to Fly ! ! ! !
where you will make your most HP is making sure they all have the same seat pressure
& that they essentially have the same valve spring stack height or relatively the same
chamber profile
you realy dont want some valve higher or lower than others
it will screw with your Compression Ratio per cylinder .........
& your crank will notice the difference ! ! ! ! ! ! ! ! !

some street use. more break in than anything last summer but plan on doing more next summer

no suprise there the last run down the track was bacfiring pretty badly from the valve stuck open(on a big nitrous pass no less). hard to say what was being blown into the airbox and transfered to other cylinders
no less do you or did you at teardown do a compression or leak down test
very important
yes its posted above, please read the whole thread before commenting it saves time
way toooooooo much of crap deposits on your valves foran all drag engine
if you are "booty" crusin around hooters you are wilting your rings
the motor was mapped very rich all season except 1 race due to an air leak around the wideband sensor messing up readings. the problem has been corrected. it ran richer on nitrous. "wilting my rings"???
coating your pistons wont help much drag racing
they rarely get that hot for the minute your engine is fired up
you dont think making 300 hp is going to get hot? this bike will see lsr too.....
a " Molybdenum" coat on the skirts will benefit more in an all drag engine

if they are that loose in the ports ......................more than likely reversion problems
huh? do you have a 12? have you put a muzzy pipe on one?
now on the photos...........................& IM REALLY not RAGGIN ON YOU
I DONT KNOW HOW YOU CAN GET 3 OUT OF THE 4 HOLES OF THE HEAD OR THE BLOCK ???????? Vincent really was the best at takin great photos
if im taking a pic of 2 combustion chambers to show chamber mods up close, dont expect to see 4. sometimes part of a 3rd gets in the pic... i have pics of all 4 that have been posted before
yet what i really want you to see [alth i cant see them all]
are the many different colors of the valves...............................no less representing
the many different TEMPS & possibly Oil
um... the pic above shows ALL the valves. again, do you have a zx12r? some of them got coolant on them when i pulled the head. it changes the colour a lot in the pic.
nest time b4 the anxious rush to install the hyped ^ glorified perf parts gauranteed
to bring you glory ? ? ? ? ? ? read your engine properly ! !! ! ! ! ! ! !!
......
the adjustments you make.......or you can correct will actually give you your Performance GAIN
stock pistons cant handle the amount of nitrous JEs can.....
i think i saw someone mention the valve seats were phat
with serdi 5 angle valve jobs.........DO IT......the ONLY way to Fly ! ! ! !
bronze seats, it has its own thread
where you will make your most HP is making sure they all have the same seat pressure
& that they essentially have the same valve spring stack height or relatively the same
chamber profile
valve spring stack height or chamber profile? huh?
you realy dont want some valve higher or lower than others
it will screw with your Compression Ratio per cylinder .........
& your crank will notice the difference ! ! ! ! ! ! ! ! !
thats pretty basic stuff...how is it relevent?
not trying to be a jerk here, but do you own and do motor work on a zx12r? you really make me wonder when you say you cant see all the valves when all 16 are posted above....
