fork oil
MrDavo:
My oil seals had made it obvious they were shot by filling the lower part of the gaiters with oily gunge. I got a litre of 10-30 from Halfords, in the bike section. I got new seals from David Silver, with the forks off the bike and the spring caps and oil seal circlips removed (I bought a pair of circlip pliers with a 90 degree bend, again Halfords) the old seals came straight out with a sharp pull, driven by the 'top hat' bush below the seal. I was worried at first that there was no sign of the plain washer between the seal and the circlip shown in my parts book, but the Honda manual explains that this was deleted when they changed the seal.
Using my race bike set up experience, I may play around with different oil weights, or even fit Progressive springs, but I wanted to go 'Honda stock' so I have a baseline setting to compare with. My Sportster was way too soft as supplied new, so I went heavier oil and Progressive springs to good effect as well as much better ground clearance.

I'd be tempted to change them anyway...

Chris400F:
Yes, you would need to remove these parts.
But you should be able to support the calipers somehow e.g. suspend them from the handlebars with some string or wire, so you shouldn't have to disconnect anything.
Just don't squeeze the brake lever while in this state.
MrDavo:
I hung the caliper from the horizontal cross brace on the frame, below the steering head, with a large zip tie. No problem, because of the flexible lower hose.
Once the front wheel is out, its a five minute job to remove the mudguard and the 3 caliper bolts, dont forget to undo the threaded caliper adjuster, once you have taken the nut off.

Actually I have 2 callipers and one of them has 15 spacers. Definitely no need to remove the forks from the trees.
