I have a 2004 500ss that is my wife's sled. I haven't drove it for a while so I don't know how long it's been doing this. Idling and midrange is perfect until you crack the throttle and hold it. It pulls hard right to 7800-7900 Rpms then bogs out, then comes back, then bogs etc...if you let off and creep back up it's like there is nothing wrong. It's just bogging at wot. I will post a pic of the plugs. The mag side is running lean during time of engine bog. New plugs, dissected carbs, even swapped carbs from another 500ss cause I was so stuck on fuel delivery being the issue....carb boots good, y pipe good, pick up line good, raves cleaned, reeds good, good compression hot and cold, swapped the coil. I am going to do a leak down test next to rule out a couple more things. At first I was stuck on fuel delivery but the cutting out almost seems electrical. Could it be a stator or voltage regulator? There are no other faulty electrical symptoms. Any input greatly appreciated.
