i had my 500 repainted,we went with 2mm for the top one,then a 2mm gap(black)then 1mm for the second stripe,we carried the forward curve further aswell,measuring on the right hand side,from the most forward part of the "A" on the honda badge is 70mm to the inside stripe,your painting a 750 tank though so that aspect is different,im still trying to work out how to post photos,.
