Mines in Blackpool Honda right now due to the pre-load adjuster knob seizing up. When I tried to add an extra click of preload in Scotland a couple of weeks ago (due to being fully luggaged up) I couldn't manage it as it wouldn't budge!!
I've since found out that it is a common problem on the VFR1200F (on which the CT frame and suspension is based) and when I dropped the bike in last weekend the service guy said they had changed a few VFR1200F rear shocks under the warranty scheme.
I am trailering the bike home next weekend and removing the 'warranty replacement shock' to sell on (not had confirmation of acceptance just yet) and replacing it with a full Hyperpro rear shock absorber unit to hopefully stop the rear end 'wallowing' on fast sweeping bends. I am also doing the forks with the Hyperpro replacement progressive springs/oil.
I ordered the basic (adjustable by 'C' spanner pre-load rings) version as the Hyperpro 'remote adjuster' version was nearly £300 dearer but I'm getting both ends upgraded at a cost of less than £500 whereas the Honda rear shock alone is almost a GRAND to buy
Allroadtoad and others have recommended the Hyperpro stuff from personal experience of using it and I also have a couple of mates who swear by the Hyperpro brand
I have had to 'fettle' suspension on cracking bikes before and can only say it is well worth the effort and expence, much cheaper than swopping bikes to chase the holy grail of a good handling machine
