looks like you have made the cover over the motor box were u can get to it by adding a block to run screws down in. I would think the RF inference thing is blocked by a foam tire and the gear being made out of carbon fiber....

one other note how do u feel about felt clunks i run those on all the gasers as they'll work in filtering along with being heavy to suck up the fuel in a sponge fashion if u get down to the wire..
