I'm pretty sure the process is to remove forks (OBVIOUSLY)
Then use a stripper (aircraft, citrustrip, whatever) to remove the paint.
Sand using degreaser or WD-40 or water at 320, 400, 600, 800
Polish with a buffing wheel using black, rouge, then white maybe.
Reinstall.
I've done it on the old honda, but not on the triumph. I'm pretty sure it's just that simple.
Tape off your tubes and seal areas if you're not going to disassemble the fork, but I'd recommend disassembling and replacing seals, oil, maybe upgrading springs if you're into that shit.
Other than that, good luck.
Someone else can amend this if necessary. I'm dead dog tired.
