I have an 2004 arctic cat 900 EFI mountain cat. I had a ECU problem this summer and ended up replacing the ECU, stator, ignition everything and know i have developed a low end bog. It bogs really bad when i start out or anytime i let off from full throttle. If i can get it above 5000 it runs awesome. I have also cleaned and put new power valves on it. i am running out of ideas and the local shop is scratching there head. I saw your web page and was wondering if you had any ideas for a solutions. Thanks.
