What HP do you get from that mod.
 

HP gains. I have taken the best gains in HP power for each mod off the Dyno sheet, not the max peak power reading but the best result for that mod. I have before & after runs of all of these mods that I tested on the Dyno.

By just adding up the totals of each mod will not come to the same total in HP when tested on the Dyno, when combining mods you may get even more or less HP then the totals added up from below. I have posted many Dyno sheets on the forum for different bikes with the same mods, so I have chosen one bike & took the results for that bike, so there may be results out there that differ marginally. Use this as a guide line & not an exact science.

+ Standard filter, snorkel removed, Kev air box mod. = 0.5HP

+Stage 1 filter & snorkel removed = 1.2 HP

+Kev fuel mod, no other mods. = 1.6HP

+Kev fuel mod, Kev airbox mod, no filters. = 4.8HP (Which shows there is still a 1/2 HP to get from the air box)

+PCIII. = 2.0HP but your fueling is correct over the whole fuel range & power is improved across the whole rev range. Test was with ccc, stage 1 & 2 filters snorkel removed airbox drilled. The gain would be less if the PCIII was on a standard bike with no mods.

i am thinking about shortening my standard cans by apprx 3to 4 ins cutting down to allow end caps to be put back in place and allowing the use of the factory mountings as still to look standard but apprx 3to4 ins shorter . can you please tell me if this is possible as to not affect fuelling or smooth running of the engine etc/etc this is mainly for sound reasons more than anything else . also i have been told that the fuelling can be adjusted from the clock pod , please can you tell me how to do this if you know. kind regards darren stephens .:yahoo:

What are you going to do about the solid cat in the pipe, if you try to cut it, it will break up. You will need to gut the whole pipe & pack it with a baffle.

Any change to the exhaust will effect the running, you adjust the CO1 up or fit a fuelling device.

Lots of info here for you.

Where to buy this?

+DNA stage 2 filter only, standard main filter = 3.1HP. (Best gain in HP & torque for your money.)

Not to sure in Norway, I would contact your local bike shop.

Otherwise

Kev,

Please excuse my ignorance - what does this mean? There is only ONE Air Filter on the XT660, isn't there?

The bike comes standard with one main filter in the air box.

We fit a second filter which is called a stage 2 filter, this filter replaces the air box side cover, the air box cover is permanently removed & the stage 2 filter takes it's place. With the extra air that the stage 2 filter offers we can get a 3.1HP gain in power.

Stage 2 filter

Stage 1 filter.

The nice stainless steel cover can be bought from Worry Brother by PM or from the forums shop on the main page. http://www.xt660.com/site/node/194 .

The stage 2 DNA filter can be fitted with or without the stainless steel cover, the stainless cover is just bling.

Thank you, Kev. That seems like a great "return on investment", I have duly ordered up both of them.

Fitted mods.
 

Had me xtx for a month now. Started wit the Snorkal removal and the dash CO1 adjustment. Seemed to reduce the serging a little and stopped the cutting out in the middle of busy roads and of roadabouts!
Replaced the standard stage 2 filter with a K&N which just seemd to make it sound more throaty?
Purchased one of Kevs fuel mods and fitted. (So easy with the intrustions!!Nice one Kev) The bike now only has a minor surge in the mid range which is livable at the mo and I'll probabley adjust a bit of riding to sort that. Power seems to have increased right through the rev range which is probably me grabbing bigger hand fulls and luvin every second!!:)

Overall seems to be money well spent on Mods for the xtx. Thanx for your superb mod kev and the other bits that can with it! Great little package for the cash and saved a small fortune rather than getting a power commander!!

Thanks for the feed back glad you like the results.:smilies0942:

Hello, i just bought Tenere 2010.
What do you suggest to do with my bike first to upgrade as much HP and not spend too much money. Is there some rule with which upgrade to begin?
Is there warranty broken if i do these upgrades?

Stage 1, stage 2, the stage 3 filters all depends on the money you want spend. Stage 1 & 2 filters can be run with the Kev Fuel mod or Power Commander, if you fit all 3 filters you will need a Power Commander.

Mods affecting warranty.
Just to clear up things, any addition to the wiring or any mod to a motorcycle will void warranty of the replacement part, if the mod can be proven to be the fault or cause of the failure of the component.

Hello Kev, how much power gains 2mm Throttle body?

2 to 3hp up top depending on your mods. http://www.xt660.com/showthread.php?t=9621

is it ok to put stage 1 and 2 DNA filters on my xt660x without a dynojet powercommander?

What year XTX do you have?

If you want the A/F ratio to be in a safe zone, then yes I would recommend you to fit a fueling device either a power comander or one of my fuel mods if you don't have the cash

Have a read in the mod section there is plenty of info there for you. Click on the blue link below.

it is a 2007

For a XTX 2007 model with O2 sensor you need to fit a Power Commander + a O2 eliminator or emulator to get the fuelling right.

thanks kev

I guess I'm being silly...
 

Hi, I noticed that the DNA stage 1+2 produces more HP with Kev mod than with Powercommanderaccording to the listed result. That feels somehow weird, since one should be able to map the fueling just right with a Powercommander. The listed results seem to show that this was tested with the same bike on the same dyno. What gives, or is it just that the Kev mod was hitting the peak power, while PC was going for best fuel economy or driveability, not maximum power?

Quite correct, the Power Commander was tested as it came out of the box with the base map which comes pre-installed in the Power Commader from Dyno Jet, not a Custom make fuel made to produce the best all round performance which the owner would have to pay extra for after buying a Power Commander.

During the tests mentioned the Kev fuel mod was adjusted to produce the best HP, both mods were test as the customer would receive them out of the box.

Is there a similar guide to this only with torque gains?
I'm thinking we mostly use our bikes below 100 km/h and torque would be more beneficial. What's best to focus on if you want more torque?

If you look at the thread links mod come with the dyno charts which also have torque charts withing them

Big bore standard XT660 cam produces good torque, all the dyno runs are on the threads.

i have leovince cans with baffles,pipercross filter,snorkel removed and co level increased from 6 to 16.power gain??? the bike is faster surely.
if i will put the kev's fuel mod, it will change the fuel consumption?

Adjusting the Co1 to 16 will only effect the A/F ratio at part throttle & does not increase the fuelling after 2% throttle. There will be on power increase from CO1 adjustments, it will help with surging up to 2% throttle opening.

The Kev fuel mod can adjust the fuelling across the whole RPM & throttle range, the fuel mod can increase the consumption by around 5%.

For best performance fit a DNA stage 2 air filter + my fuel mod & you will have a smile everytime you crank open the throttle.

Well I've fallen into the trap!!!!,I have Kevs mod and it runs very nicely thank you,after much thought on a KTM 690SMC and decided against it, couldn't resist buying a PC it'll be interesting to see the difference.

A Power Commander + custom Dyno map is the way to go if you have the funds.

Well it'll have to stay in the box for a while with 3 days at the Stafford classic bike show this coming fri/sat/sun and then off to Estoril for the Portugese GP for week,I'll put my two peneeth in when I come back.

hi guys!
i recently dyno my mt03 and i have i question about how much hp will gain after remapping the stock ecu(Piasini)!
my mods +2mm throttle body.mod airbox with dna st1 and giannelli cans!
bike put out 50.8whp!

I currently
mivv oval, bmc stage1, dna stage2 , pc3. everything else is original.
+Carbon Cans only. 2.2HP +Stage1 & 2 DNA Filters snorkel removed. 3.8HP (bmc is low) +PCIII. 2.0HP = 8HP - 1HP bmc = total mod up my xt ~7HP

how much hp and torque I take if I put dna stage3 and +2mm bigger throttle body whit mapping right?
,
DNA stage 3 Air Box Mod + PCIII custom fuel map + Cans 8.33 HP +2mm bigger throttle body 2HP = total project 12,33HP

difference 12,33hp - 7hp = 5,33HP and little torque?

Do you know about how mutch power/torgue the OTR header pipes can give with Leovince,dna stage 1+2,PCV-O2 controller?
Also what should i do with O2?When i got leovince and a filter i increased it 15 units.
Now with power commander should i set it back to default value?

K&N or DNA Stage1?
 

Hi,

Actually I have Akrapovic cans, K&N Air filter, Snorkel out and PCIII on my 2009 XTX.

I am going to mount DNA Stage 2, and next year I will go to a Racing company to make a new and personal map for PC3. I want to know if it will be a good idea to change the K&N air filter for a DNA Stage 1 (59�), or if it's not going to make a big difference.

I want to get the more HP increase that I can, so also I want to know if it's a good idea to remove the lambda sensor or not.

The DNA filters flow more air compared to the K&N filters, due to larger pleats in the weave of the filter.

Hi

I am a new owner Yamaha 2005 with 11k kilometers. I am planing to go for DNA stage 1+2 and after market cans + Kev's fuel mode. Somebody told me if I change the cans, I should buy also PCIII or PCV, to change the engine plan. Is it correct? Should I buy it?

thnks

A power commander is one of your best options as it can tune the mapping in every fuel cell we have many map setup in the ASK KEV section for PCV & PCIII,


Next option would be one of my fuel mods which is a basic tuning tool & will do the job: https://www.xt660.com/home/kev-shop/#fuel-mod
