well, because the build cost for this bike has alredy toped $1400, im keeping costs down by making my own tank. The plan? using a seat post only mounted rack, cutting it short so it does not stick out in front of the tank, got a little 10"x5"x5" go cart tank that im going to hide in a round leather harley bag, bolt the whole thing down and away I go, ill post pics when im done. thanks for all the help and info
