Kev's Fuel mod and O2 eliminator for 07-08's
 

As you know I am one of the 07 owners and unfortunately another one of those who believed that the surging thing was sorted out on 07's...hmmmmm :019:

well, I was facing surging (at low and mid revs) as well as cutting offs basically while downshifting.
I recently bought Kev's fuel mod mark III for 07-08's --it was actually before the O2 eliminator was also availlable-- . So, after I fitted my DNA stage 2 filter (ooooh yes!!! big difference but the fueling had to be adjusted as well...) I bought the "affordable" power commander made by KEV, "the wizard of OZ" as I wish to call him... :smile[2]:
Results were impressive!!! A bit more of power --as most difference felt because of the DNA filter-- but most of all, the bike smoothed out and stopped acting like a crazy horse!!!
However I was still facing a bit of surging at low to mid revs... not that annoying compared to the wild thing that was there previously.
Well I thought that .... this is it! As good as it can be... so I just had to learn to live this way... a bit of surging at low-mid revs.
But KEV seems to NOT being satisfied until he does things PERFECT!!! :smilies0346: or else he just can't sleep at night !!:BangHead:
So...here comes the O2 eliminator that succeeded to solve the problem right there!!!
I was so badly trying to persuade myself that surging was still there... that I was increasing revs bit by bit on each gear to be able to spot the rev level that surging starts... NO LUCK!!! Just because SURGING WAS NOT THERE ANYMORE!!!!!! :woo::woo:!!!!
Even if it was 00:30 (and I had to wake up at 6:00 to go to work..:googly[1]: I kept on riding under all situations..slow ride in traffic... normal ride ..up to hi speed - accelerations - wheelies - downshifting and everything!!!
I have a new bike and I owe this to Kev, CaptMoto and XT660.com!!!
Thank you all!!!! Thank you so much!!!:icon_salut::beer[1]::yahoo::bounce016:

all you 07-08 owners... mark my words. KEV's Fuel Mod Mark III and O2 eliminator.. is waiting to make your bike happy and you..even happier :byesmiley::occasion14:

Once again well done Kev, and great news for you George now your bike is finally running as it should.

With this finding we have established that to succombe the problems with surning on the 2007-8 models you are going to need A Kev Mod Mark III and the all important 02 eliminator also supplied by Kev.

Great news

Good news George. I had the same results on my bike as you know.

Basiclly the 07 with O2 sensor is still lean in the lower & mid range rpms & my fuel mod will help with low to mid range leaness, the only difference is now the 07 model is a little rich in the higher rpms 60% throttle & above, where the 04 to 06 models was lean accross the whole range.

If you are after a better ride low to mid range my fuel mod with a O2 sensor will help, if you are after power across the whole range & want to correct the fuel mixture across the whole range then a Power Commander is the best option.

I am here to provide the facts & not to promote my mods.

J-Maker,

I to have fitted the PC3 and O2 eliminator, and wow, wot a big big difference it really makes.

To all 07-08 XT owners, i can not reiteriate enough what j-maker has said, trust me on this, it is a must and the bike you have afterwards is a real real pleasure to ride through town and in low rev range.

Nice One

WB

so how much is it kev and can i just fit the o2 eliminator or do you need to fit both.

Unless you are willing to go the power commander route which as Kev says is the ultimate fuelling device you can happily go around it with a cheaper solution which is to get DNA stage 1 & 2 Filters, and the Kev Mod Mark III + 02 Elimintator. I would recomend this, because it will leave you more budget for a decent set of Carbon Cans!!! :icon_salut:

Andy there is a gain in just fitting the O2 Eliminator it will help with the surging, the O2 sensor will need to be removed & a blanking plug fitted. The blanking plug can be bought from your local exhaust shop. I have not been able to find the correct O2 sensor plugs yet, so I would recommend to to by it from the UK if you want a plug & play connector. I can make up a O2 Eliminator but you would need to connect 4 wires to the loom as George did then tape up the Eliminator to make it water tight.

If you are going to fit DNA stage 1 & 2 filters or cans, I would recommend that a fueling device to be fitted with the Eliminator. George found with his stage 2 filter fitted with standard pipes he had to increase the fueling to get the best ride.

If you are happy with your bike then leave it alone, as we have found some of the 07 models with O2 sensor run just fine & do not need any modification.

The KevIII Fuel mod costs AUD$100.00 which includes postage. It is now for sale.

If anyone is handy with eletronics & they want to make there own, I can give you the full details on how to make them, they are very easy to make. As I have said before, my mods are to help riders & not to make a profit off them.:FlowersAndHeart_SL3

I have already fitted stainless steel stubbies capt but not sure if i want to go down changing all the filters on the bike just yet and can`t afford a power comander.
So looking for a cheaper route to help with the surging and cutting out problem if that`s possible.

Does that last offer includes free barbeque and bring your own beers?

:what:
:toothy9::bbq[1]::occasion14::occasion14::hahaha[1]::rofl[1]:

Gonna make my 02 eliminator today/tomorrow. Not going to make the fuel mod though - i will buy a PC5 within few months.

My surging problem has went worse within last few months, cannot figure out yet, why, since i have done all necessary diagnostics, cleaned every single contact, changed spark plugs etc. My friend has a 07xtr which is pretty much stock and he rode mine, he said that sometimes it feels like my bike is not getting enough or is getting too much fuel, when suddenly accelerating from low revs. the jerkyness is sometimes annoying... it is almost cutting out sometimes in low revs, especially when coming out of curves, it feels bad when the bike does it. otherwise, at higher speeds, bike runs great.

I have:
OTR 2-in-1 complete exhaust system with db killer removed
snorkel removed
ais blocked off
rerouted engine breather
air filter is foam filter from OTR

Hey Pipz can you please let Kev know which serial number is your TPS and ask him to help you set the correct lean angle on the TPS, also have you tied to raise you idleing speed (tickover)

There are a lot of XT's out there with faulty TPS's and ECU's and I suspect by the sympthoms you descrived your bike might be one of those. As I've said please get in touch with Kev to try and eliminate causes. That might save you money in the long run, because a PC5 might not cure existing problems.

tps angle was set to 16. You did mean serial number of my ECU though?

Actually we need to know first what is the code on your TPS too, A2 or A1, then also your ECU serial number but first of all need to understand which TPS you have. thanks
