As a postscript, I'm just back from a 168mile tour round Derbyshire - Glossop - Buxton - Ashbourne - Denby - then home via Ollerton using B roads where possible. MrsW navigating.
As a result of the adjustment and lubrication, the steering is noticeably sweeter, and lighter. The difference is obvious. We left at 0700 so had the roads to ourselves for a couple of hours. Saw a gaggle of Caterhams, an odd MX5, and MGB, the obligatory Blonde in a white Merc SLK - but little else. Lots of Motorbikes.
An excellent run out and just over half a tank still showing on the fuel gauge.
