Here's how I did Mike Wattners battery relocation, pretty close to how Spud did his.
I powder coated a piece of sheet metal and cut the ridge off around the air inlet hole and then pop riveted the metal plate over the inlet hole.
I then placed some velcro on the plate and a piece to the back side of the battery and stuck it in place, it's as solid as the rock of gibraltar with no movement, it's actualy hard to pull off the bracket.
I'm still going to place some foam and ti-straps around the battery cuz I know how hard Wattner rides his bike.
I also drilled some new holes in the air box for air since I blocked the inlet.
I left the plate back a tad so some air could still be pulled in around the battery..
