- The charge is for 'post and packaging', so you should always expect to pay a bit more than just the postal cost for the time and materials involved in packing it up and getting it ready for the courier.

- Every international courier I've dealt with works in 'volumetric weight', in other words they have some sort of formula which turns the size of the package into a 'weight' which they charge you. This means you end up paying a lot to send big items, even if they don't weigh very much. Try pricing up the cost of sending a piece of sportsbike bodywork (weighing a few grams) across Europe. I suspect this is why DNA can't reduce their postage costs - every extra item you put in makes the box bigger, even though filters aren't heavy.


Re: Power Commanders.

They are the most common brand of a range of products designed to allow you to alter the fuelling of a bike with fuel injection, in order to maintain the correct fuelling when aftermarket parts such as exhausts and (in this case) air filters are used. They are plugged into the bike's Engine Control Unit (ECU) and tell the ECU to inject extra fuel depending on the engine RPM and throttle opening. This is important because by fitting a filter which allows more air in, you need more fuel to maintain the correct air:fuel ratio.

Their website is here - http://www.powercommander.com/powerc...r/default.aspx - but any decent bike shop should be able to source and fit one for you.

To make it work, you need a 'map', which is loaded by connecting the Power Commander to a computer. It sounds like you will get one supplied with the DNA kit, and the shop that fits it should be able to load it for you.

Now that's a good starting point, but in an ideal world, you should put your bike on a dyno and have that map altered slightly to suit your exact bike - your engine will inevitably be slightly different to the one DNA have used to produce the supplied map. Again you should be able to find a bike shop or tuner near you who can provide this service.
