I'm in desparate need of the expertise of you guys.
A DNA air filter has finally been made for my beloved Shiver. It runs 18% more air than the standard one.
In the DNA blurb it does say you don't need mods and the bike does have lots of sensors and a pretty flexible ECU.
I already have Leo Vince exhausts on the bike.
My question is... do you think the bike will cope without any fueling mods wothout running too lean.
There is also a GPR power-commander available for it now.
Have any of you guys fitted one of these or heard of them?
Are they any good? I guess the combination of the three will give me a fair wack more power.

I haven't heard of a GPR power commander before now, I guess it's the same people that make the rotary steering damper in the US?
With the filter and the can it'll probably still run a bit lean. The ECU can only correct within a small range.
You'll get more power with a mapping anyway. Haven't dynojet released a PCIII version for it yet?

Nah.
It has oxygen sensors and all kinds of thingies including ride by wire and three maps.
I think it needs the PC V
Not that many sold, though now the Dorsoduro is out and selling quite well it will hopefully come soon.

I dunno if your ECU is anything like mine but I popped into a local bike shop that used to be an Aprilia dealer and they advised me that fitting one to my bike wasn't worth it as map 2 worked well without one and they found the PC wasn't really wioth the effort on the Factory.

That may be the case for a standard bike but any mods like air filters and exhausts defo need a power commander and dyno run/custom map to be right.I took my completely standard k7 750 onto a dyno and the fueling was all over the place.A bike is never perfect without a custom map.There are some bikes that have a standard ecu that can be mapped but i believe its a much cruder mapping and less refined than a custom map on a power commander

Unfortunately Dynojet don't have one for my bike and don't plan to make one in the near future.
Hence my question about the GPR Powercommander.

I'd be insecure about non-Australian or non-OEM air filter.
With all the dry weather over the last few years, my OEM filter was shagged after 6000k's.
The reason I say non-Aus filters also, is that we have the smallest dust in the world (oldest land mass on the planet).
[hey, a first where Aussies claim a small thing]
Something that flows more air, flows more dust ....
Maybe it is wet enough in your neck of paradise.

Byron bay sounds very damp a lot of the time-interesting about tiny dust though.

DNA say theirs filters out 99% dust, while the original, which is also not Australian (obviously) filters less.
There is an oil layer in the DNA whilst the Original is just paper.
I didn't even know there were aussie filters. Who?
It is pretty damp here. Lowest humidity I've ever seen was 45%.

Uni Filters Australia. They do roadbikes also, though not a Shiver.

Bought it now.
As the O2 sensor checks how much there is in the exhaust and send more fuel if needed I'm hoping it will compensate.
Someone on the AF1 forum has fitted one and says it runs smooth as.

Just something I picked up on the other day, some bikes with O2 sensors only use them over the first part of the throttle opening (some use them all the way, BMW?). (I could be wrong, I have been before).
I think this is due to the O2 sensor not being so good when things get richer. The O2 sensor is keeping things under control for emissions testing at the lower rev range.
But hey, it is most likely all fine.

I think it is possible that the O2 sensor in the Shiver is used more.
The engine is latest technology and (at least in the blurb) says it is constantly adjusting fueling for prevailing conditions etc etc.
There is a post on the Shiver forum that says the PCV will be available for ALL modern bikes soonish so I'll just wait for that.
I've spent enough on it recently anyway.
Got a rear spring (Hyperpro progressive) coming soon which should be good.

The O2 sensor is made with fuel economy in mind rather than performance. I don't know whether the Shiver has a wide band O2 sensor (the newest type), most bikes have narrowband sensor which really only tinkers with the air/fuel mix a little and fairly slowly too.
Your filter will probably be okay, but if it were me, I would have a quick (cheap) dyno run just to be sure.

The idea of a dyno run is pretty good.
I've been thinking of getting one done as a baseline to see where the bikes stands as standard, then as you mod it (or things fail).
Not sure if you have any near Byron, but Springwood Suzuki have a good rep. (and I'm sure there are some dynos down the Gold Coast). I think it is about $125 at SS.

Good idea.
I will do that once the air filter is on.
