CBR400 NC23 Aero rebuild/upgrading

[Celis93]

Hello,

I am currently rebuilding my first bike.
Since it hasn't ran for a while, I am completely servicing it.
I haven't got my drivers licence yet, so I have plenty of time to rebuild the bike

I will replace the following things:

- battery (DONE)
- brake seals
- brake pads
- engine oil
- oil filter
- spark plugs (DONE)
- chain and sprockets
- check valve clearances

So next thing I want to do is servicing the front forks.
New seals and dust seals.
Are the front forks of an Aero any different from the other NC23's (RRJ/RRK) ?
Will progressive springs be an good investment?

Any other things I absolutely should check or replace?

Thanks!

The forks are similar to a CBR600fh, which are fine.
Do the brake caliper pins and rubbers.
