You can get the PowerCommander through Simon (on here) for a very good price already setup with a map for the DNA filter. I takes about an hour of so to fit to the bike (depending on your own skill) but the effects are very noticable.

As Kev says, a 14t front sprocket (�13 from www.wemoto.com) will give you some more bottom end, I'll let you know how this works with the PC-V after I've had a chance to fit it! I am anticipating another quatum leap in power delivery as it's already much more responsive with the PC & DNA

Hi ! have decided to go for the Kev fuel mod and DNA filters. Looking forward to get the stuff.

As far as I can see there is not much weight gain in any 3.party exhaust change. On my KTM I saved a lot of kilos going from stock to Acrapovic.

Cheers

Guys,

what sort of gain are we talking about by installing fuel mod and DNA filters while keeping stock exhaust? and I dont only mean in terms of numbers but mostly in real life experience.

Cheers

I am about to find that out. Parts are coming and as soon as I have the KEV mod I will test.

I will test two things :

1. Stage 2 with air restrictor(no fuel mod)
2. Stage 2 with Kev fuel mod

I want to have the possiblity to run "stock". I live in one of the most restricted countries in the world. If they start whit EU-check's on bikes I want to be able to switch back to default flow.

With the PC-V you can have dual maps, so you can switch back very easily (and of course you need to swap the filter, or you could get a restrictor for the DNA filter?)

Ok, I didn't know it was possible to get the stock "fueling" with the PC-V. Is that a bypass function ?

As I understand the tank must off to get access to the PC-V. That would be some work for every service etc..

With the Kev Mod it would only be to turn the knob to "zero" and insert the restrictor.

Since we are talking about PC-V, do you know what price it is sold for here at XT660.com ? Guess it is cheaper then here in Norway even if I have to pay for shipping.

You put a switch on the PC-V, to switch between the two maps - simple!

No need to remove it for servicing and the tank only needs to come of for the first installation.

I've no idea about 'zero-ing' the Kev mod (Kev ??) to return to stock, but I can't see why not.

In both cases I think it's a case of switch/knob and restrictor, so easily reversed.

Ok, that is nice to know :) Thanks

so you are happy with the DNA/ PC-V combination ?

I am considering PC-V but since I have ordered the Kev-mod I will give that a try.

PC-V seems to be the more "correct" way of doing it but I don't want to spend hundreds of Euro on dyno testing. (if one of the existing maps don't fit my bike)

Very, although I wasn't convinced until I got the bike back out on the road.

You should speak to SimonC, depending on your setup there may be a map available. Sure you should get it tuned on a Dyno as every bike will have minor differences, but I'mm willing to put money on it that I wouldn't notice the difference (on mine) if it was.

I think you are right to try the Kev-Mod first. If it's just a filter you are changing then there's not relay any reason to spend the extra ��. If you then add other mods you should go for something like a PC-v

I have ordered DNA filter and the DNA snorkel removal kit.

did you do any other serious tuning to your bike ?

I will contact Simon for the PC-V when the time comes. First I will test and report back to the forum.
