Update - I done the fork oil today, and made an arse of it. Explanation...
There are two washers, one with a hole and one without. The one without goes on top. I, like a total idiot, reassembled the forks with them in the wrong order. I put them back on the bike, locked up the garage and came in the house. It was in the shower I had my "eureka" moment, and realised that I have wasted my day and my new oil.
So, let's look at the positives...This being my first go, I now know how NOT to do it. Also, the forks and all those components are getting the royal treatment as the new oil will be flushed out and replaced in a couple of days, this time with better stuff.
It only seems right I put up the good with the bad here, and hopefully I can save someone making the same mistake as myself.
