I run one for two years on an 2007 bagger and it did exactly what it was supposed to. I since went to a pro race fueler as I got a bit more knowledge about fuel injection and tuning but heck, for years I put an S&S E on every darn bike I owned. The 07 was my first injected bike. My fuel mileage increased with the fueler and heat was a bit easier on them 98 plus days here in Tidewater. Gave my set up to a buddy running a bone stock motor and he loves it. If your question is does it work, yes in my opinion. Is it easy to work, yes in my opinion . The downfall, is once I did cams, 103 and heads I needed a little more and basically at that point the Cobra did nothing for me. Ask yourself what am I going to do to this bike and if the answer is ride it. Buy the Cobra. If future motor mods are planned, spend the extra money for a better fuel management system.
just my two.
