Moto Airbox Power Gains

Great. Anyone else? Mine is an 06 S.D. with round open akras and std. KTM akra map. Runs really badly on steady throttle around 3000 rpm, fine everywhere else. Does anyone know if the motobox will run on this as is, or will it need PC3 and custom map to run?

It is advisable to seek professional counsel,

the Moto box is spectacular but as far a the actual #'s I am reserved to say to let the the record speak for itself.

OH yea of little faith, let your expectations voice themselves, you will be shocked by this outpouring of horsepower and torque.

Joseph!

Always helping out. You're a good man. I don't care what they say...Yeh, I'm definitely going to put on the Motobox and pull the 'flies. I know the 'flies routine from some other bikes, and I just can't see it not helping. The only thing I'm worried about is the bike running well (Obviously.), and being too lean at lower revs. I sure would like to see a Air/Fuel graph from a dyno before I set it up. I'm not the technical type, and I hate messing w/this stuff (Love riding. Hate wrenching.). I want to do it all at once. Anyway, I've been waiting for a while. I thought some brave, knowledgeable soul would have given it a detailed go by now.

In any event, I hope all is well. If you get around Atlanta, give me a holler. Thanks, again.

Hey Chris, I like to race the hi HP porches in the mountains over next to suches on those rockin 3 lanes and I use the whole road to stomp those rich boys in thare fancy toys, show um what HP $$ is all about!!!

be sure and get me hooked up with some of those Appalachian mad men when i come dood !!! we all have talked of my shenanigans from those trips in GA. I freakin love your roads!!!

I remember backin the big 1991 gsxr 1186, bored and ported for torque, I could back the monster in and had 160 rwhp, what a hoot it was but the cops did not like us so we had to go back to fontana... bunch of die hard bikers... ahhh... the memories overwhelm me

Highlander, I think the bike to bike comparison will be worth at least as much as the dyno results if not more. I look forward to your results, as all I have read here about the Motobox is good, but back to back testing in the real world seems more real to me. Side by side roll-ons will tell a tale, as well as general rideability and the old 3000RPM glitch. Have you thought about pulling the butterflies out also? Could be interesting perhaps. Cheers.

Hey Guys, Just got back from the dyno shop after installing the "MOTOBOX" Wow what a great improvment! 8 horsepower, and 6 more foot pounds of torque! This is on the same dyno about 6 months apart. bike is an 07SD, with akra slip ons, PCIII, sas removed, flies removed 2-3 gear limiter by passed, This simple mod really makes a differance in real world riding. I can pull a higher gear out of corners. and much smoother getting on the gas. This is how the bike should come from the factory! there is alot more sound from the intake,when the motor is under a heavy load. Sounds like a pro stock race car, very cool ! Big thanks to MH for making a great product. The only thing I did notice is I can hear a ticking noise comming from the airbox area. It is only there under hard acceleration? kinda like a pinging sound from a lean condition, but I know it is not lean from the dyno results ( custom 2 cylinder map) AF ratio of 13.5. overall I am very pleased, just wish I had done it sooner. Thanks agian Moto!!. Tim

Hey Tim,

You're gonn be hearing all kinds of strange noises coming from that area now. I've got an occasional screeching noise which I've not sussed yet.

How did the fueling look prior to re-mapping?

I happen to have an extra ECU if we can get an exchage deal worked out

Thank you guys for the acknowledgment on this HALLMARK ISSUE! I am not the tinkering type.

Most people think of a technician or in my era a mechanic as someone who loves to tinker with stuff... not me.

I have watched the conversation closely since I first came in here, this is one area I generally will give no comment or opinion.. much to the astonishment of some others,

the reason is... I know very little about the alteration of these particular systems, I am factory trained on many makes and this is a strictly forbidden area left to the engineers.

I like to leave some things to the experts and this is one of the few, I like to pay other people for their expertise and knowledge.

The tune boy from what I have read in this particular forum is more of a PC geeks dream come true, this is not my area, I want to plug and play.

This may be an arena that needs exploring and I may need to break into this over here on this side of the pond...

it is refreshing to see this and I hope we can get KTM's attention with this...

IMO this is an area that KTM needs to follow my example and hire someone more competent than the ones who have been in charge until now or create a team to iron out the wrinkles.

On the O-2 sensor issue, this is particularly touchy and controversial. The adaptability in real world applications are fantastic and revolutionary when it comes to O-2 sensors and how they work, unfortunately the SD is a weak link in the chain and it has it's apparent short comings.. I paid for it and if I can successfully reinstate the application I would be thrilled, it makes perfect sense to me. At the racetrack this, the comment about the O-2 sensors does not apply, but when you are touring and going from one extreme to the next, altitude, barometric pressure, temperature and humidity, it is backwards not to have the O-2 sensors in an operational state. The ECU is a snap to change.. spech since I have no trouble with a tank remount...

Hey Highlander, I understand what you mean, it's not just all about peak horsepower, but response and how it gets up there. Torque and midrange fattened make a very enjoyable ride. So whats your bike? year and mods? I can't recall asking you before. And be nice to the missus, cos I'd love to see the graphs. Cheers.

Yesterday evening our local Pikes Peak superstar Dirt4breakfast made the drive from Santa Fe NM here to denver for a motobox. On the way thru town to my house he stoped in at Faster motorsports for a baseline dyno run of his SDR, Run file 003. We instaled the motobox last night and they put it back on the dyno at Faster this morning and did the remap, run file 015.

The chart speaks for its self

Beautiful. Love that fat midrange. Looks like it was a strong bike to start with too, but that midrange would just grunt out of the corners now, good result.

hey people

my bike is an 07 sd . has ti graves cans , pc 3 and of course the superb motobox fitted with the fram filter . i was sent a map from dynojet hq in the uk that was a rich ( very rich ) but safe map for me to do get the sd the 90 miles down the road for its dyno runs and set up after fitting the motobox which weakened the motor off drastically on its previous map . bike was much stronger and very smooth but a bit fluffy at the top end , and bloody hell was the old girl thirsty . so after a custom map for each cylinder i have some results .

before 108.51 rear wheel hp and 70.79 ft-lbs

after 121.51 rear wheel hp and 77.37 ft-lbs

the af ratio was bloody horrendous , all over the bloody spot . now is a nice smooth trace all the way .

now that in my eyes is a bloody awesome result and i dont give a bloody toss what anybody has to say but i put the result square on the shoulders of Aaron and the motobox .
together with cans a pc3 and a custom set up i dont think there is a better way to improve our toys .
i am waiting for the bloke who mapped the bike to e-mail me the graphs and as soon as i have them i will post them .
cheers Aaron .

take it easy

Hey Moto,

I told you once the word got out you'd need to fire up that mill! Glad to see so much positive feedback and absolutely nothing negative.

I'm still here in the UK so won't be able to get my bike to the dyno anytime soon but as soon as I get home and get it re-maped I'll post up the numbers.

John

Another one in the tribe! Another one that sits on the MOTOBOX and has only one face: and then and then... and then...
Not tuned the map yet, the PCIII alredy fitted, with the O2 eliminators on...
The bike has A LOT MORE, starting from 3k till the rev limiter....
The fuelling on mine was perfect before, so nothing to complain on that side, and now the throttle response is just a little more smooth but so much stronger...
At little openings I feel the bike is pulling more and now in the bends opening the throttle make the rear slide very frequently...
And the sound.... OMFG!!! That roar..... aaahhhhh!!!!!


All in all a must-have mod!!!

Thanks to Aaron MH!!!

yup , what he said . the dyno man will use his wide band sensor on one cylinder at a time to give you a custom twin cylinder map . i took the sensors off altogether and used bungs to block the holes off so i dont have to look at the sensors - fugly things that they are .

take it easy

Ok, I received Moto Box and block off plates a few weeks ago. Thanks Moto. Installed the Moto Box the following weekend(Dirtbike Hillclimb weekend. Good time due to having some of the bikes loaded in truck for Sundays Hillclimb) I started the job at 6:pm and was done at about 8:30Pm, I took my time. It can be done faster.

Started bike for the first time with Moto Box, fired right up. Secondary TB plates ringing like a tunning fork. after bike warmed up ringing stopped. It only rings at a certain RPM but is not herd while ridding bike. Note, It is no louder than befor at idle.

Took SDR for its first test ride that night. Throttle respone is cleaner.
My ride has Power Commanded installed with Graves pips installed. Duel cyclinder Dyno mapped. The bike feel smoother through the throttle with more torque. (My seat of my butt dyno}. Whack the throotle open, front end comes right up at a lower rpm. ( I love torque ) What surpprized me is now it come up in second gear as essay as first gear. I was doing like 50 somthing opened the thottle she came right up like my dirt bke. Nice.

I took it down and had in Dyno Friday. Just as my seat of my butt felt. The Dyno showed more torq in the lower rpm's. Lost a little hp at the top but that 's ok. Max Torque: 71.89 was 69.71. Max Hp: 123.26 was 125.26. See Dyno below. As you can see the curv is much smoother now. The dip at 6k and 7.5k is gone. Tuner said no adjustment is needed. Fuel/Air mix was still good. It shows a slite leaner condision. obove 5k, 13.2 rather than the 13.1 but the curv is so smooth now there was no reason to adjust it. Here the Dyno Chart below, enjoy. Note the Block off plates were installed and smoge removed with resister installed just before Dyano was done.

Fitting my MotoBox today. Sooo excited to feel and hear the difference. Will post up later how it went.
Dyno is happening end of next week of beginning of week after so will scan and post the chart up then.

Ok fitted Aaron's MotoBox today and I have to say its amazing. The noise is incredible, I really didn't believe it would be that noisy. I did the job in a friends workshop and we were both just grinning and laughing when i started it up and rev'd it

The actual fitting took about 2 hours in all. I have only lifted the tank a handful of times before and have never delved into the airbox. The instructions on here were spot on. I'm no mechanic but have a fair understanding and these made the job easy. Decided to not run the risk of the rubber grommets at the rear of the tank distorting and so removed it completely. This gave me plenty of room to work in too.

Initial impressions apart from the incredible noise are that it seems to have gained in mid range. I think it might be running slightly lean but i could be wrong. Its being dyno'd in the next 2 weeks anyway. The only slightly strange thing is a noise that comes when I give it a big handful. Its almost like a mechanical knocking or vibration but could be something else. It seems coming from the front of the engine but again i could be wrong. I didn't get to really ride it as the weather has been shite but I might get a chance tomorrow. I'm sure its nothing serious but has anyone else noticed anything. Itr hasn't affected performance as it goes like a rocket! My m8 rode it and did noticed it too. He said it almost sounds mechanical but couldn't think what it might be.
Oh and my throttle bodies whistle on the overrun. Sounds quite nice.

Cheers Aaron, fab bit of kit.


Couple of pics with shitty iphone camera

Here at last are the results of my two days at the dyno.All being well they should be dated.The 2008 one is when I had the HATTECH pipes fitted,otherwise standard.
2009 chart is as above plus MOTOBOX added and smog equipment removed.
Bike runs a lot stronger now even though it "appears" to have lost power..same dyno and operator but about a year apart.Not sure of smoothing and correction factors applied to charts I'm afraid.
Sorry it took so long..I've a few images to add to the forum but I still can't do this even after being shown!![/img]

Hey Highlander its easy to post pics on here. I took a screen grab of the Photobucket site where you uploaded your graphs. All you have to do is copy and paste the code from where it says "share this image" use the "IMG Code" and paste into here. Thats it, your pic will appear straight here.

Thanks again,I'll give this a try tonight with wife to assist,she knows more about it all than me.
