CB750 / 750 SOHC Gearbox

Got a problem with the gearbox on my 750sohc. After building the unit up I have found that there is a noise from the gearbox when in neutral when running. Its as if there is a dog on one of the shafts that is to close to the corresponding cog that it mates to. When I press the selector drum in the noise gets worse and when I pull it out it seems to clear the noise. When I say pull it out there is only a few thou end float but it does make a difference. I have now stripped the engine and looking at the gearbox find it hard to see anything wrong(all the circlips and washers are present. The only thing I can think of is that maybe one of the selector forks could be slightly bent and not clearing the cogs enough. Any thoughts anyone? Also does anyone have a set of selector forks(3) they can sell me then I can compare with mine
