@JMo (& piglet) and @Oyabun Thank you for the (super fast!!) replies! I'll tear the forks down again when the fork gaiters I ordered get in (from the UK) and replace the 10W with 5W (and to double/triple check the innards are correct). Going to keep riding it until then, because more riding is always better than less riding. I think my CB might have enough UK sourced parts on it soon to be registered as a citizen there. Or at least dual citizenship.
