DNA kit
 

I have read all the posts (I think) and have located a DNA dealer near me but has anyone fitted the kit to their bike yet ?
Would be interested in any feedback.
Having had 6 WR enduro bikes many of the guys drilled holes in the airbox and removed the snorkel to improve fueling etc.

On the Z the filter is on the inlet to the airbox, not the outlet to the engine as most other bikes are. Because of this the integrity of the box cannot be compromised or unfiltered air will enter the engine. There is a thread here somewhere about people reducing or removing the snorkel but remember it also serves to keep water out. (I know JMo has reduced hers). But in reality, unless you want to competely re-design your air box theres nothing you can do with it.

Just my 2 cents....OGR

Good point, i can't believe no one has tried the kit yet :102:

Nor can I.

One of the reason why no one has yet tried this kit is perhaps the fact that they are hard to get and I can't find a stockist in UK as yet. So ideally for the time being they are only available directly from DNA Filters Ltd. and hopefully through us in the near future. :)

breathe freely!
 

I don't have the DNA kit, but I do have a K&N filter fitted, with the snorkel removed from the airbox, so the airbox lid is the same as the DNA one.
I think it's a worthwhile mod, as the motor does feel more "snappy", but I haven't had the time to get it on a dyno and check it out. My next mod when time allows will be a PCIII and a dyno session!

Well i don't like waiting so i will be the test pilot, mine ordered and should arrive Tuesday from the UK distributer :024:

Hi Den, who is the UK distributer? How does the price compare with offtheroad.de ?

Has anyone ordered from DNA direct or contacted the bloke who has registered here? Any discounts on offer?

Should also note that I don't think the DNA guy recommends adding the filter and snorkel replacement cover without adjusting fuelling via a Power commander or such like. I think it's ok with the filter alone but snorkel removal may be a step too far.

Be careful with this folks because I'm speaking from experience having holed a piston on an 1150GS just by adding a can and y-piece!

UK distributor is based in Hereford B R Special tuning http://www.motorcycle-exhausts.co.uk/index.php

Cheers Den, I've ordered both bits. Good prices too.

All I need now is a PC3 and single end can!!

:023:

I have the kit DNA filter and Stage 2 cover.(not fitted)
I am still running in although I have fitted my leovince cans I have not fitted DNA yet as fuelling need to be adjusted. I have the PCIII to fit also.

My plans are get first service out of the way then book my bike onto dyno then fit PCIII on zero map and drive to the dyno. I will fit the air filter at the dyno centre.

Reason I am doing it this way is it says explicitly on DNA fitting instructions to get fuelling adjusted as soon as fitted or damage may occur.

I have spoke to Dino from DNA about a PCIII map but has not done a dyno run with Ten and PCIII fitted as far as I can make out. Or no map available at this time at least.

I got my kit direct from DNA no worries. It was cheaper than OTR.

Does anyone know for sure that a power commander is required ?

If you change JUST the air filter then no, if you change the air filter, and remove the snorkel then I would advise that you DID fit a PCIII and have it mapped to suit. Think about it, you are allowing much more air into the engine and so the fuel needs to be increased to suit. Otherwise you are in lean territory and at risk of burning out valves and holing pistons.

So the Fi ain't clever enough to adapt ? I was just thinking, DNA kit �50'ish PC3 �300 and starts to sound like an expensive upgrade for what gains ?
Maybe i have jumped in feet 1st as usual, not having much luck, Kappa rails are welded up wrong and a potential fault on the new tankbag. oh well

Try to find a used PCIII on ebay.
PCIII for Aprillia Pegaso 2005 on or Yam XTX/XTR will suit. You will need to get it set up on dyno unless you can find a map somewhere. I hope to have my map done next few weeks.

Cost more than �50 for the filter plus stage 2 cover.

I make it about �72 for both. Should be worth it tho. (that was with cleaner and oil kit)

Den did you see this thread http://www.xt660.com/showthread.php?t=9636 ?

Some interesting reading and I think the potential gains sound good. Powercommander is expensive but not as much as replacing a piston. Even a couple more horses will be very noticeable on a bike with not many to start with. Depends what you want out of the bike I guess. Probably not worth it if you're riding on green lanes most of the time but I'm doing a lot of road miles and fancy a wee bit more top end poke.

Well smoother fueling and a bit more umph would be good and i suppose if i do buy one i could put it on another bike if i ever sell this one. Come to think of it i cannot think of many Fi bikes i have ridden with spot on fueling, me mates zzr14 is very good thats about the only one i have ridden in the last 12m that had good fueling

I have fitted DNA filter and Stage 2 cover (plus leovince cans) and had bike Dyno mapped. Tested with snorkel bike was running lean.

Result is about 3 HP more after Stage 2 fitted and mapped. I didnt get test with standard filter and exhaust set up so I dont know total gain.

Once mapped the throttle response is much better and seems to need less throttle for power when needed. Slight feeling of power increase but nothing to shout about.

Bike overall runs very well feels smother and more responsive I cant say any more than that really.

Dyno guy reckons it could be more economical. We will see.

I wouldnt advise anyone to run the DNA filter and/or stage 2 without getting fuelling checked as Dyno guy reckoned it was running way too weak before mapping. (even with snorkel on) Just as DNA warn in their fitting instruction.

Nice work, any chance of a dyno print out?

Dyno chart
 

Blue is with Leovince cans DNA air filter and standard snorkel before mapping. PCIII was running a zero map at that time.

Red shows differecne after DNA stage 2 fitted and mapping complete.

As above the improvement can be felt and runs smooth on all throttle position.

AIS was clamped during mapping.

The dyno tuner has done a good job on the tune, not only did he get good HP gain there is a good amount of torque as well. I thought the A/F ratio might have been better a better around the 2200 to 2750rpm mark, you would have picked up a bit more power if it was a bit leaner in those ranges. The XTX & R's show a similar result.

Can you send me the fuel map, I have PM you my E-mail address, thanks.

Tuner told me he has a problem at that range you speak of as something was countering eveytime he tried to smooth it out. He also said harleys also have a similar spot in thier fuel mapping. So he did all he could and didnt miss it out. I would recommend Highland Motorcycle Dyno of Cromarty http://www.hmdtuning.co.uk/ to anyone in North of Scotland. Very thourough and freindly. And the best thing is there are some lovely roads on the way to and from Cromarty no matter where you live in Scotland. So you will be able to test the before and after properly.

Glad the Kawa O2 Eliminator worked for you, as I mentioned my O2 Eliminator is the same spec as the one you used.

Looking at the chart I notice the torque is way down at very low revs with the mods fitted.

Just wondering if this is something normal with these mods or an anomaly of some kind? If it's normal just wondering how noticable it is?

TQ has good increased. The dip you see is normal for a single/twin on a dyno if accelerating from lower rev range. It is showing the bike overcome the dyno force. You can see in dyno video clip I posted tuner covers clutch in case of stallout and you can hear engine labour before accelerate. Other charts that dont show this dip are usually when revs have not dropped so low.

I don't see any loss in torque, the dyno run should be read from 2500rpm not before. The results all depend on when the dyno tuner starts the run & in this case is at 2500rpm.

Well done StinkyPete, I think you might be the first one who actually got the Tenere dynoed. I would be curious to know from your future feedback on fuel consumption, any savings or losses. I hope your Tuner is right that it actually saves some, but would like to see hard evidence. Also, I presume you don't mean less vibration on the handlebar when you say it feels smoother, right? Meanwhile, enjoy your new dynoed bike!

Ah thanks. That would explain quite a lot :)

In 99% of custom fuel maps been made, the fuel consumption will improve due to a higher torque per throttle position. Due to the higher torque you tend to roll the throttle off to maintain the same cruising speed.

Well i am taking my DNA kit to Dynojet tomorrow 1st thing to get mine sorted as i bought the kit and can't fit it without risking a hole in me piston :rolleyes:
Hopefully i may get to take some photo's and i will let you know how i get on, its a bloody long way to walk back if it goes bang mind !

You got a PCIII or buying?

you will also need from Dynojet

Good luck.

Thanks Kev.

Pete, it is mr dynojet who's doing it so hopefully he will have all the kit :headbang:

looking forward to the 3hr journey and the rain i don't mind but gales i hate

Well 300 mile round trip in gale force winds, hours of work by Martin on the Dyno and i have my DNA kit fitted with custom map and PC V nessling under the seat a very interesting and informative day and he kindly allowed me to annoy him all day, top bloke.

You just left me hanging, more info needed???

1/ What are the dyno run results.
2/ Did you get Auto tune as well?
3/ Is the O2 sensor connected or disconnected?
4/ Did you use the Kawa O2 Eliminator?
5/ Did you fit the map selection button for the PCV?
6/ Please can you attach your fuel map in a PM to me. As this is the first PCV fuel map made for a XT, I would like to add it to the fuel map section.
