Kev fuel mod or Power Commander 5 ?
 

I'm planning to fit the 02 Controller then either Kevs fuel Mod or a PC5
What is the advantage in paying more for a PC5 against the cheaper Kev fuel mod?
I'm assuming there's more scope for tuning with the PC5?

I'll be fitting a different exhaust (probably the Exan Oval X Black) plus removing the snorkel and fitting a different filter (OTR foam ond oil).

I see there is also a 02 controller that comes with the PC5 ?

thanks....

Fit the O2 controller first and feel the difference, then get yourself a Kev mod to start off with. Kev's fuelling mod will do a fine job of adjusting the fuelling to suit stage 1, 2 or 3 air filters and you will notice yet more power and particularly tractability as the usable rev range expands by 1500rpm+. �/bhp there is no cheaper solution than Kev's O2 controller and fuelling mod combo (with DNA filters).

Save your money and get a PCV later on when/if you get bored and fancy another change (which is what I did). The PCV is a more complete solution to fuelling and allows you to better fine tune your setup, but to make the most out of it you do have to fork out another couple of hundred quid for a dyno session. You will easily be able to sell on Kev's two mods and recoup most of your money.

If you fancy it though, and you've got the cash for a PCV and a dyno session, then go for it from the off.

thanks Pleiades, great information again!
As I thought the PC5 has more options; I'll see how finances go over the next few weeks. I'm planning to change the exhaust also and to run foam filters which I believe will be better for use in dusty conditions (Morocco trip end of this year) and for that reason I'd like a perfect set up.
I believe the PC has an option where its possible to swop between 2 modes, perhaps one for economy on a long trip then switch the power setting when required? I'm going to look into this.

From what I read on here the 2 Kev mods transform the bike.

How does the DNA filter compare with the foam filter OTR are selling?

The DNA filters flow more air than foam, as all cotton gauze filters do. Power/torque will be greater. However, as you rightly suggest, the foam option is the better bet in dusty conditions.

A lot of people use the OTR foam filter, it is apparently better than the Pipercross (which has been known to fall apart).

Another advantage of foam is you can keep a spare, pre-oiled element squeezed into a ziplock bag ready for a quick change in the field. Carrying a spare DNA filter wouldn't be practical, being a lot heavier and taking up more room.

Let me tell you, the DNA stage 3 + PCV setup turns it into a real hooligan bike.

But be prepared to pay!

�360 for the Exan exhaust
�270 for the PCV + O2 eliminator
�120 for the DNA filters
�240 for separate dyno runs and fine tuning.
�100+ for fitting (do it yourself)

Hmmmm, that's a lot of money I've spent.

But 51.8bhp on the back wheel...

Hmmmm, is it worth it?
You decide.

I would go for Kev mods, DNA stage 2, and a 2 into 1 exhaust and then give it 10,000 miles to decide whether you want to spend the rest... Or buy a different bike!

thanks for the answers guys, i guess it all comes down to ��� and how much I love the bike. Just ordered the Exan exhaust and OTR foam filter....

All that money will buy a lot of petrol and could be a lot of exploring.

Yes I know but I as I'm planning to keep the bike and do some big trips on it, I'd like it to be set up perfectly.
I've been speaking to the dyno guy at PDQ today and yes it's going to cost.

Weave will give you good advise as he has done so much of that and quite recently. He is also doing a big big trip soon which will show which bits really really work
