152 hp????
Took 1270 to dyno......152hp?, would explain the 9.92 @ 140, yeah, 240 is still on it, I did however remove the air ride to try n lower 60', ran 9.75 @ 140 last year, total weight is 760, anyway, took it to get compression n leakdown test, 230-24o n all 4 cylinders, 7% was the leakdown percentage, took valve cover off n checked cams n valve lash, cams still sitting at 104.5/105, n lash was good, so where has my 19-20 hp and 10 ftlbs of torque go???? Just removed clean air and going to tune again, I read that sometimes that system will read false afr's, would a failing fuel pump kill hp but still show a 12.8-13 afr on dyno? Bike had 171 n 98 when first built and this was with 240 on bike

A horsepower calculator that iv'e used with accuracy with Rickey Gadson's runs gives me 162.7 horsepower for you weight and
Elapsed time and MPH.. 9.75@140mph at 760 pounds.
Question what was the ambient temperature, air density, and correction factor when you went to the dyno? Also what is the condition of your air filter? When is the last time your injectors were cleaned? Is the tire pressure on your bike correct? From my numbers your only down 9 horsepower from before. We can probably find the 9 horsepower..

The 9.75 run was last year, its posted somewhere on here, lol, the dyno pull was this past wed night, im thinking it was bout 50 degrees outside, warmer n the dyno room but I really couldn't tell u temp, it was in millville new jersey, tire pressure was 32 psi, air filter is clean (bmc race), injectors have never been cleaned as I know of, I've ran injection cleaner but im guessing that's not the cleaning ur referring too, lol, and I've had the bike since 06, even with the 9.75 run it was still down 10 hp, was just trying to explore all possibilities of why the loss while the engine is still checking out as if its still strong, was hoping its the fuel pump, lol, I'll do the pressure check this week

Make sure your oil isn't over filled. The zx12r will lose horsepower if is over the specified oil level...keep us posted..

12.8 - 13 WITH kleen air hooked up?!? Then you are too rich.
Spark plug age and condition?!?
Can you also compare your UN corrected #'s??

no charts or graphs available, after the tune and i was pretty much pissed, lol, so i loaded my bike up and let my friends zx10 put down 160, smh, Plugs where a little dark, they were changed end of last season, maybe 4 months ago, not too many miles on them, non where white or wet, You say 12.8-13 will actually be to rich with the kleen air still on the bike, well i hope its pic rich if thats the case, lol, I do recall looking at the afr line and while it was close to 13 in spots it never went over the line from 3000 rpms to rev limiter. Lets just say it was a long 2 hour ride back home after that, and now after the tests where done on the motor I left wondering what the hell is wrong, I got it at a shop here in dover, now that the kleen air is off we'll try it again (dyno). Not the same dyno but an increase from a base pull is an increase regardless of the numbers it shows. The guys name is Harvel, he is in southern jersey area, bridgeton, nj, he has a website, Harvel performance,

Remember if your running a little rich, your bike might run better on the road but make less HP on the dyno. You do have ram air compensation to consider. 12.8 to 13.3 is a good afr. I would change the oil, make sure you have the correct level...

We'll check what the afr is on the next session since we've taken the kleen air off, i'll let yall know what the outcome is, what the afr is on the first pull and how much had to be done to get it back.....if its off to begin with

No ones ever had a fuel pump deteoriating yet still have the afr in tact? Guess it would go lean on the big end if its wasnt doing its job though.....anyway, just thinking outloud, lord knows i've cursed enough the past few days, funny thing is the bike runs and feels good, but when you see 1270 numbers and the mine dont match, then you have all the tests come back good, makes you wonder what the hell is really going on doesnt it? And just to be clear the numbers where 171 and 98, but i'll post up whatever happens this week, an oil change and retuning without the kleen air, maybe new plugs, but i'll post printouts and everything, thanks for the insight and help though

I would NOT go anywhere above 13:1 AFR on a 1270 .
Also keep in mind the ECU will richen the engine at high speeds. It uses the pressure sensor in the tail in conjunction with the intake sensor to determine what fuel table to run during high speed operation.
Make sure your plugs are fresh to light off all the needed fuel to keep the 1270 CR happy.
How many miles on the plugs?!? Condition? Are they stock plugs?

I dont know which plugs I used actually, maybe 1000 miles on plugs, like I said they were good, i'll have to check each header pipe to see what temps are going on and if they're close in relation to one another, is it possible a sensor in the tail or intake is bad and just not throwing an fi light?, limp mode, lol

Well, looks like supra was right, 162.4 was first pull, clutch slippage on the top end initially, numbers were 162 n 85, ended with 166 n 90, still low for bike even with 240, im going to try n get a stock wheel n put on same dyno n see what im losing, I'll post dyno graph as soon as photo bucket resets my password LOL

you might have a duno with a low correction factor. Not all dynos read the same. I think your bike is fine. I wouldnt mess with it internally. Where are the lobe centers on your cam timing?

I have a Barnett at this moment, got it cause it was there, im 100% sure oem wit hd springs will b my next purchase after these burn up, lol, 104.5/105 were the numbers, motor is good, the back wheel is what's hurting me, looking for a set of stock wheels to find out just how much, then it'll b on sale for 4500-5000, want a 14 now n im sure alot will b sold for decent prices since the 2012 is here, I just can't sell my 12 the way it sits for less than 6800, the tire kit alone was 5400, lol,
