Tudor Panait Posted June 25, 2012 Share Posted June 25, 2012 Hello everyone, I own a 650 DragStar which I purchased one year ago from a previous owner. I just noticed recently that there is some sort (or half installed) liquid cooling system on it. However, there is no radiator. I searched over the internet and I couldn't find anything about this but I found a picture with another DragStar with the same system installed (I attached the picture). You can see a black plastic container near the first cylinder. https://www.dropbox....wywe2net/11.jpg https://www.dropbox....t8vks0ym/22.jpg Does anyone know anything about this "system"? Is it a known customization? How is it supposed to work? It doesn't seem to work now but I want to make it work with someone's advice/help. Thanks, Tudor Link to comment Share on other sites More sharing options...
Ttaskmaster Posted June 25, 2012 Share Posted June 25, 2012 I know certain States in the US have to have some kind of device that restricts the emission level. Is it one of those, perhaps? Or maybe a liquid cooling system jury-rigged from another bike? Given that the Drag is designed to be air-cooled, I can't see either the point or the reasoning behind fitting one, really.

Tudor Panait Posted June 25, 2012 Author Share Posted June 25, 2012 I know certain States in the US have to have some kind of device that restricts the emission level. Is it one of those, perhaps? I checked my bike this evening and there is a hose connecting the fuel tank and this black container. There are hoses connecting the container and the cylinders (I only checked one but I think it connects to both). There are also electrical wires going into this container. You might be right and it can be an emission restriction device - if this is truly controlling the amount of gas pumping into cylinders, I am wondering if I'll get more power by simply disconnecting it.

Tudor Panait Posted June 25, 2012 Author Share Posted June 25, 2012 Okay so I looked over the internet for emission control devices for DragStar and it appears that my little black container is called AIS - it somehow pumps air to help burn any un-burned fuel thus reducing emissions. However, I don't know if removing it will increase engine power, any experience with this? Link to comment Share on other sites More sharing options...

PeterC Posted June 26, 2012 Share Posted June 26, 2012 It is the 'air induction system' and if you google it you get lots of hits shows you how to take it off Link to comment Share on other sites More sharing options...
