as far as i know all district forks are really hard to get a starnut in. they are meant for ICS not SCS or HIC. try putting the starnut through the bottom of the fork, apparently that works. if not, you could drill a bigger hole down the centre of the fork tube to make it larger. hope this helps!
yeah i just tried putting it in trough the bottom and i almost got it in and then it just got stuck and wont go any further at all. i guess im just going to have to drill it out and try again.
