Yeah< It took some time but man is it worth It.. only got a couple of hundred miles on it. But WOW !!! big balls,, VERY HAPPY !!!!!!!!!!!!!!!!!!!!!!!!!
Now I can continue my quest..... spanking busas!!!!!!!!!!!!!!!!!!!!!

I hope you enjoy it. That might be my quest someday.
Did you build the motor or have it done by a shop?

Had It built by someone else

Man I'm glad to hear you are enjoying that BIG BORE :) I'm suppose to pickup the BIGG12 this friday :D :D :D after two and a half months of waiting for my 1290 kit, head porting and a few other odds and ends installation. Can't hardly wait until Friday! :D :D :D . Good lucky with the 1270 and ride safe, will keep anyone post on the 1290. I will still have to carry the BIGG12 some where to have her tune with a custom map. Lets kick some Busas' tales :) :) :)

Your going to love that big bore !!!!!My bike smoothed out so much, Its hard to believe !! and the power increase !! all I can say Is holy shit !!! even in 6th gear at 90 roll on, man what a difference she winds up so much faster,, I cant wait for the weekend to go out and pick a couple of fights .Its going to be a different story for the suzuki Boys. there going to freakin HATE ME hahahahahaha Look for my post on monday Ill post a summary of how bad I killed them LOLOLOLOLOLOLOL

Al you bully what are doing picking on people smaller than you .

we now that i look at it at 1270 you are still smaller than those big 1299 :shock: busas. so pick as many fights as you can.

That is the sad part, they find out you have a 1270 or 1290 12R and they whine that you are cheating. Hell, you are just evening out the playing field :D To bad a 1270 12R motor spanks a 1299 Busa motor.

Well Took Her Out On friday for a few test runs.She Ran 203 mph on motor!!! Not too bad I thought>Saturday Went for the proper map.Only 185 hp WTF !!!!!!!!! Started checking And found The fuel pressure drops off dramatically at 10.000 rpm NOT GOOD Killing 10 20 hp And motor Is leaning Out At WOT. Im lucky I didnt Burn Up the motor On that 203 mph pass But The Good news Is With A Good Pump She Will go even faster Thats right 203 mph With 185 hp. Imagine what she will do with 300 hp Im looking for that 218 mph record. I might pull It Off

Is it just a worn out pump or not enough pump?

What do bone stock 12R's do for power on that same dyno???

I pulled away from phantoms 12 and he was spraying a 40 shot
and I believe Its just a worn out pump
Phantoms bike makes 175 Hp on motor

Cool! 8)

You should get an upgraded fuel pump. Apparently the stock pump is only good for about 180 HP. I was told things could run lean because of the duty cycle of the stock pump. Hate to see you blow up your brand new 1270 because of something dumb and relatively inexpensive. I ordered mine from Spencers for 189.00

189.00 bucks ??????????? son of a bitch !!!!!!! The dealer just charged me 500 bucks.Dammit!!!!!!!!!!!!!!! Im not sure about the stock pump being only good to 180 hp I hope your wrong............But on that note we are about to find out. being that I already ordered one And the bike goes back on the dyno.If your right .The pump will show Its ass When We try too pull 200 hp out of the motor. and then spray to 300 hp....... 189 bucks ????/ man that burns my ass!!!!!!

I do believe that I would tell the dealer to keep that bad boy!

I don't understand how they could have the nerve to charge you $500. It ain't like Muzzy's price is secret:

There's an article in Schnitz's tech corner by Doug Meyer on the inadequacies of the stock A-model pump.

Mine Is A B model

It's still a good read. :wink:

What about the 02 model 12's the B models, does it needed the fuel pump upgrade after going to the Big Bore(1290 kit). My bike is starving for fuel down low :( :( , try to put enough miles on it to have it tuned on a dyno.

B-model pumps are supposed to be better, but I don't know specifics on how much HP they'll support. In my conversation w/ Muzzy's, they said that a healthy B-model pump will support a 1270/1290. If it's hurting down low, a dyno/sniffer map should cure it.

Just to clear the air.... I weigh 230lb's and Al weighs 150lb's.... that's 80 pound difference in weight. On top of that.. I wasn't spraying a 40 shot... the PSI in the bottle was at like 600psi... so it was maybe a 25 shot.

And he only pulled on me in 1st gear... once we got into 2nd and I got on the juice... I held him dead even.


I'm sure if we swapped bikes he'd RUN away from me with the juice.



Either way, the bike made 196rwhp with the new fuel pump... that's kick ass being that the compression ratio is only at 13.0:1!!!

:shock: Phantom did you say 13:1? And was that the 1270 or 1290?
I'm wanting to get around 200rwhp but on a very reliable engine. My dad and I got into this big discusion about the 13.5:1 compression ratio being too high. He said that would be good iif it was a track only bike. He said a 12.5:1 or a 13:1 would be much better. What is te difference in hp between the 12.5:1, 13:1, and the 13.5:1 in rwhp when it comes to the 1270 or 1290 kit?

Higher compression = more power.... and more heat

The Muzzy 1270 pistons come with a 13.5:1 compression ratio... which is about as high as you'd want it to be on a STREETBIKE.... Alcindus used a thicker gasket to lower the compression for the Nitrous.


At 13.5:1 Al's bike would have made 200+rwhp easy.... but it wouldn't be able to handle much Nitrous for a long duration...which is what his application is set up for.


The 13.5:1 is very streetable... It's when you get into the 14:1 that you're going to run into reliability issues..

Also, if you want 200rwhp SAE out of a ZX12R... you're going to need that 1270 kit + Muzzy cams + oversized valve job + headwork + TB overbore + lighten/balanced rods and pistons + all the usual bolt-on's like full exhaust, air filters, pc3usb, etc...


Then you're going to want an undercut tranny so that you are not popping out of gear here and there due to the power.



So you're looking at quite a hefty bill at the end of the day.....


I don't even want to repeat what Alcindus' bill was after he had all of the above done to his 12R.

My bikey is going on the dyno in about an hour. I can't take the anticipation!

Here are my mods

Carpenter 1290 kit
Carpenter race head w/cams, titanium springs/retainers, CNC port
Falicon Billet Basket
Muzzy Lock up clutch/hub
Muzzy Fuel Pump
crank balanced and lightened
Carillo rods
dual 40 shot NOS
PCIIIr
Full Muzzy exhaust

Wish me luck!

Al,

What gearing are you running on your 1270?

Thanks,

Red

I switch back and forth, depending on what Im doing.for around town I like 17-46 for top end runs I been running 18-44 good for 205 mph. will gear for 215 mph on the juice

i know this is like 2 months old, but i'm a new member browsing the forums, and got really curious as to what it ran. By the way, i'm considering getting rid of my R1 for a 12R. The more threads i read here, the more convinced i get about getting the 12.

Well Greenzx pilot. What she pull?????
