Hey, here is something else though, went out a little while ago, rode to a friends. Bike seems really smooth with stock airbox and 0,0,0. Had him ride it around town, I followed him in my car while he ran the piss out of it and not one time did I see smoke. If it is smoking it is in such small amounts you cant see it from behind. He even revved it at stop lights, no smoke. When we got home I revved it hard(to about 6 or 7k) in neutral,no smoke only when abusing it by revving it to about 8 or 9k did I see any smoke and it was very light whisps of black, no gray, no blue, just a little black. I think I am going to map it 5,5,5 just to be safe but I honestly don't think there is a damn thing wrong with the motor except for maybe needing a little more FI tuning. What is sad is now I have to lie to this guy and tell I did a leak down test and it is fine just so he will tune with an air fuel meter and a dyno. The dyno he has is a Eddy Current brake dyno. He usually only gets about 145hp out of a piped and mapped Busa, that sucks!

A leak down tool is always good to have in the toolbox!
I really believe there is NOTHING wrong with your Busa. It looks to Me like it's just a matter of needing to know how to adjust with the Yosh box. When your bike was smoking it was rich. If it was smoking through the mid range thats where you need to lean it out. If it hesitates on the low end it's lean. Richen it up untill the hesitation goes away.
If it's lean on the TOP it's going to sound/feel like it has a fouled plug. Richen it up untill it just starts to pull good.
I can go futher on this but I'll wait for more details.

Alan,
Why lie to him. If you are in doubt just run the leak down test. It doesn't take long and isn't hard to do.
Around here Checker auto parts will even loan you a leak down tester ($50 deposit so that you bring it back). The only difficulty you will have is getting an adapter to the metric plug hole. I got mine (for GSXR) by special order from a local tool store but snap-on carries them. It is cost effective for a little piece of mind.

Frank, I have tried every possible combination with the Yosh box, It runs the same every time. On the B adj I have gone first 0,5,10 made 155 hp, remapped 5,5,0 went up to 159 hp but had bad hesitation. That was with the dyno shop's yosh box. I have tried 5,5,5; 5,5,10;10,5,5; and even 0,0,0 and I have changed the Idle circuit every where from 10:30 up to 12 oclock.This was with my Yosh BOx, its new but is it possible to be screwed up?? All of this was with the half box mod,short stacks, NO PAIR and Yosh Duplex,stock clutch. The bike ran consistant 9.90's-91 at 145.5 and had run a best of 9.85@146.08, 1.76 60'. Had hesitations but made good power.
Then I did the full air box mod and uni filter, took bike to track on shitty weather night my best was 10.0 @144. I even tried remapping several times at the track.
Ran Redline, put in more fresh fuel, fresh plugs, CLUTCH mod&springs and tried again last night and I averaged 10.11's at 144 and my best was a single 9.93 at 144. My 60' was only 1.85. I left smooth but the bike just didnt pull, it was slower all the way through. I usually average 120 mph in the 1/8 but last night averaged 117. Did not powerwheelie at ALL, used to every time in first gear.THe weather was identical to the previous GOOD track nights before.
I installed a stock air box and set the ecm back to 0,0,0 I will try the track again tomorrow night. If it is quicker I will leave the box alone if it is slower or the same, I will half mod it, put it at 5,5,0 and leave the damn thing alone and if it coughs I may try a PCII I think my bike should be in the 9.70's with full box and clutch mod dont you guys???Hell it went 9.80's before!!

you gotta make sure your openings line up between the box and frame or you'll leak on one side and block half the air intake hole.do as i posted in the airbox alertsection .please.you'll see what i mean.

ALAN, Most of what I've read from guys having trouble useing a Yosh box end up solving most of it by investing in a pw2. Only reason I'm reccomending this is because you can tweak your setting a lot more with detail. You can see what particular settings your going with on your p/c and have some kind of idea on whats going on. And once you get good and understand HOW to use the pw2 you can make adjustments to your own map. Fuel, timing ect ect.
I wish I could come to the track with you and help you out!
But since I can't I would suggest putting your Yosh settings back to where it showed 159hp on the dyno. Richen up the low end ONLY where the hesitation is untill it's GONE.
Use the same airbox you did on the 159hp dyno run UNTILL you hook yourself up with a pw2.
Set your ecm back to "0 0 0" before you install the pw2!
There is enough members that have been through similar problems that one of us should be able to help you get on your feet once you get going with the pw2. Don't worry!

WHICH DIRECTION ARE YOU TURNING THE LOW SPEED ? COUNTER OR CLOCKWISE?
I have had an ongoing battle trying to get my bike tuned right. I have run the half box mod, the full box mod, and the stock box. I have a Yosh duplex. My bike has started smoking slightly when revving it hard (say to about 7k) it appears to be black or blackish grey. I have checked all vacuum hoses and sensor connections. I have tried every setting available on a Yosh adjuster box and the bike still seems to run rich.I cant tell any difference between the settings. I have had it at one dyno shop already and it left there hesitating is A$$ off. I finally found a Tuning shop with a dyno and a Air/fuel meter but the mechanic/tuner wont touch my bike because I have "ALready damaged the motor, either a ring or piston" Although he is just going on what I told him over the phone, he hasnt even seen it in person! Is this possible that I could have fried it already? It seems unlikely to me because I never returned it to the stock 0,0,0 settings until after it started smoking!It was smoking at 0,5,10 and 5,5,0. I tried to set the 0,0,0 to lean it some but it would still smoke slightly. Any Ideas? Are these things that weak that they would fry that easy? I have 3000 miles on it. It was broken in properly and I piped,mapped, and airboxed it at 1100 miles. It is about 1.5 tenths and 2 mph slower in the quarter now then it was back a month ago or about 1000 miles. Right now I have it at 0,0,0 with the stock air box but with the pipe. Seems to be smooth and runs pretty hard but I dont know.I checked the plugs today and they look pretty clean, white insulators but do have a small black ring (carbon)on the thread housing. They have only been in there for about 400 miles. That mechanic said to do a leak down test on it but he wouldnt do it. I hope someone can help me out or I am screwed!! I am in Houston, anyone reputable nearby?
Mhead: Counter clockwise, 11:00
Frank: I have tried every setting with the Yosh Box and it never seems to make a difference.Check this out: When I had the half mod box,5,5,0 and stock clutch the bike would slightly bog of the start but pull hard enough in the low range (3k to 6K) to still 60' 1.76's consistantly. I would run consistant (3 weekends in a row)9.90's-91's at 145.5 to 146mph. I did the full box mod (to the same box I had the half mod on first), mapped it 5,5,5, and the bike would barely 60' 1.9's, was 3 or 4 mph slower in the 1/8 and would only run low 10's at 143 -4.
I shut bike down, ran Redline, checked filters, fresh plugs, clutch mod and still only 60' 1.85 (only one time though)ran many 10.1's@144 and a single 9.93@144. I think with the clutch mod and air box mod it should have gone 9.70's at 147. I have had near identical hot and humid weather every time.
The bike has less low end torque, doesnt pull itself through as strong as used to and I leave higher and smoother with the clutch mod. After I let the clutch out and nail it, it just doesnt leave hard. Used to powerwheelie every time at 8K in first gear, now doesnt at all!
Tonight I am running a stock air box with flapper intact to see if it picks up on the low end. I dont think it will MPH better but the 60' times should be quicker, if not then there is something else wrong besides the air box. If it does run better then that means I just need to tune more for the big air box, maybe a PCII I did order a Leak Down tester and will test tomorrow, but I dont think the problem is in the motor, I think it is just tuning but I have definetly lost some power somewhere! I will keep you guys posted, Thanks for any suggestions!!

I don't know if you have any problem at all regarding the smoke. I put my 99 on the dyno at 2500 miles and it too would put out some faint whisps of grayish smoke but only when the dyno guy had it up to redline and when he let off the throttle.
Also, Gixxer1300 posted some video on the net with 2 hayabusas on the dyno and both of them had faint whisps of smoke under the same conditions as mine.

mine too but roll back to 10.00 i run +5+5+51100 on my stock piped 99.so i take it you checked the alignment of the box to frame holes?if not don't say i did'nt warn you.80% of the boxes i see show horrible misalignmet causing leaks and 30 %intake blockage
I am going to check it right now MHEAD.
I am going to try two different boxes and try different settings with yosh box on both boxes time permitting. I will keep you posted. I am getting a leak down tester tomorrow and checking it. Bastard is $75. I believe what you say about the big air box but I just havent got it to work on mine yet, Believe me, I dont want to pay 260 bucks for stock, **** airbox. But If I cant get the big box to run right, I will have no choice unless you pros talk me through this crap a little more on tuning the big box. Could the loss of power just be in the incorrect mapping? What yall think?

Oh yea!....You can mis out on a lot of power if it's not dialed properly.
Try this with the big box and I'm not saying it's going to work but lets see where it's at after these adjustments?
Set the idle speed at 11:45 and put the Y-box at +10+5+0
Let Me know if it still has a hesitation on the low end?

Gee Frank, you're a f**kin genius. I'll bet you burned up a lot of brain cells coming up with that one. Uhhh, lemme see, it blows black smoke up top but hesitates on the bottom, uhhhh,,, duhhhh,,,, yeah, thats it! Take away fuel up top and add some down low. Boy,,,, what would we do without you. Moron.

I think that you're going to find that your leakdown test results are OK. Whether you're talking Toyota, Briggs & Stratton, Harley, or Suzuki, as a general rule if the smoke is black, it's running rich. If the smoke is blue, you're burning oil. You can smell the difference as well.

I've been kinda hinting all along to hook yourself up with a pw2. Like I said earlier you can once you understand how to use the pw2 you can tweak & tune to where you have a better idea whats going on.
I have really yet to see anyone 100% happy with their setups from a Yosh box. The same can be some what said about the pw2 also But most of the guy's feel like they got it closer than they could with the Yosh box.
Your going to be able to bring everything closer to what you need for that big box setup with the pw2 over the Yosh box. I can't stress that enough. And you'll see once you learn how to use it.
It's complicated at first and you'll probably have a lot of questions but there is support all around.
There is other members out here that have more experience in useing it than I do...all of which I'm sure would be glad to help you through the process.

ZXALAN read my true testing post on Motorhead site I gained 5MPH
Hey Frank, I didnt get to make it to the track tonight and today I have to give the stock air box back to my buddy so I will keep trying to tune it out with the full mod mox. I have tried the 10,5,0 setting, along with every other setting, it never seems to change how it runs, hesitations on low end and slight black smoke at 7 or 8k. I have even put in a stock ECM out of a 99 stock bike and it still hesitated low and slightly smoked up high. I dont think it smokes under full load(hard to tell when riding)only when revving it in neutral, I am more worried about the loss of low end power and trap speed. I dont feel that the bike had any more low end though with the stock box. Still no power wheelies like before. I think I will keep the big box and try a PCII. Do you think that will restore the lost mph and low end? Any suggestions? I will be doing a leak down test tonight just for piece of mind. Thanks guys!!
