It does help. I too did not weigh the axles.
The reason for asking is my battery will be in the bottom of the forward baggage hold and I was told that the W&B might be an issue without the battery weight aft.
My 2 legs would be 28 pounds and yours are 40.8 pounds. Since I didn't weigh the brackets but don't need the leg fairings, I'm going call it ~ a 12 pound difference.
If an Odyssey battery weighs ~ 15 pounds, then essentially I'm adding 3 pounds forward over the standard legs and decreasing 15 pounds aft.
Total diet reduction, a SWAG of ~ 12 pounds
I wonder what effects it will have on CG calculations.
