Kev�s Fuel mods ?
 

Hi all
Does anyone know if I can add kev;s fuel mod and do the air box mod without changing the exhaust. I had all the mods done on my old XT660 but I don�t want to change the exhaust on this one as I fecked my ears up permanently after a 3 day 2000 mile ride with loud aftermarket cans on. So much so I have to use ear plugs as now even the wind hurts them. Thanks for any info

If you fit a Kev mod, you can change both the original filter with a DNA stage 1 as well as fit a stage 2.

The Mod will allow you to adjust the correct A/F ratio and keep the bike from being too lean in the mixture.

Make sure you get the correct mod for the year of your bike as follows

From 2004 to 2006 included all you need is the mod itself
From 2007 onwards you also need Kev�s 02 eliminator to control the cancelling effects of the 02 sensor or Lambda probe which is fitted to the left header of post 2007 production bikes

Good luck, and please PM Kev for further assistance in your purchase or any questions you might have

I have ARROW cans on my R...LOVE the sound...kinda like a cats purr and not loud or offensive at all.

thanks mate I know about the mods i put them on my last 2011 xt660 i did everything to that. i have an 2007 but must be a late reg as no air sensor what i need to know is can i do all the mods without changing the oem cans :icon_sad:

KEV'S mods will help as you know...the exhaust ,as you know is both heavy and restrictive,with a cat in it too i believe..

Do you want to leave the intake and exhaust stock?...tbh seems a bit pointless to put freer flowing filter(s) in with the restrictive exhaust.

The problem I have is 18 months ago I did 2000 miles in 3 days on my other xt660 with aftermarket cans on. By the 3 day I was in big trouble. Long story short my ears are now fecked the wind even does me in now after 30 mins so I have to keep quiet exhausts on and use ear plugs , and trust me it pissis me off as always have aftermarket cans. Lucky for me my fz1 and my tiger 800 one has arrow and other has akrapovic exhaust on but with the baffle in them ,they are just about ok. I am looking for a new lid to help with the noise. So was hoping to do all the mods just not change the cans. But if there is no point doing the mods without changing the cans I will,just have to leave it or put aftermarket cans on and hope my ear plugs work

Kevs mods are about smoothing the sytem out and not,as far as Im aware.out n out performance mods..

I understood the initial comments about your hearing but if your running aftermarket exhausts on two other bikes why wouldnt you on the R?..

Arrow cans,as you know sound sweet..not loud at all.Compared to my mates R,with MTC cans they are subtle..

Yes you can but don�t expect a lot of performance results, the original cans are heavily restricted

Ok thanks a lot for the info will have to see how bike rides as is ie standard and if not much cop will just have to do the lot again and hope my ears hold out with the isolat ear plugs

No problem, when you are ready we have a set of cans for every pocket

Think I would have to go for arrow as they are quite. If not the owner of Beowulf exhaust is a friend of mine so would get them from him. But I really do need quite cans if pos. taking bike out in morning for first ride so will know what I will have to do to it by the time I get home. My last one had all the mods done to it so shifted ok

Could do with some link pipes maybe

Took bike out and to my surprise it was as smooth as feck. BUT I took a risk and bought a almost new used set of aftermarket exhaust price I just could not say no to if to loud will just get rid and the kevs fuel mod so will do the air box mod and filters may as well do the lot and see if I can get some extra horses out of it. I found at 100mph it was struggling a bit. My other xt660x was fine at that speed but had all the mods on it. One thing I did find with the R something just not right about the riding position and anything over 85mph front don’t half start to wobble �� but as most of the riding is under 80 guess it will not be a problem. Can anyone let me know has anyone changed the front sprocket at all and is it worth it

Have you considered doing the fork mod?..

At the end of the day the R isnt designed as a high speed cruiser..its a 'sit up n beg' riding position..Im 6'2" and effectively an air brake when riding ...

Dont get me wrong,she sure does fly along nicely,as does my mates..I have the two DNA air filters and snorkel removed,Arrow cans,and Kevs mods fitted.

My mate has Kevs mods and MTC cans with the snorkel removed.

Mine pulls smoother and is slightly faster BUT Im four stone heavier and 6 inch taller than him..

IMHO the 'best' mod so far has been to fit new Avon Trailmasters..to both bikes.

Yeah I am taking the crap Tourance tyres off and putting on some Avon or bt45 think I will go for the Avon on this bike , I have Bridgestones on all my other bikes but the Avon Wright up was good but I am going for a road tyre not half and half I like to get the bike over and all my riding will be on road as going to get a ktm 250 exc for some green laning fun what is the fork mod

Basically a spacer the sits on top of oem spring..dimensions are 38mm wide x 30 mm high..

I used an old frame slider that my Brother turned up on a lathe.

Thanks for the info
