I ride a motorbike all year round.
In the winter like today -3c the forks feel harsh and too stiff ....it gets worse the longer i ride.
Its the viscosity of the oil in the forks changing due to temperature.
In the summer (if we get one up here) I have to add a few clicks of rebound and compression damping to compensate.
Stiction is the problem.
gt85 is an interim measure, I will start experimenting when i get the phono sockets fixed.
Thanks to everyone for the help and guidance-this whole vinyl adventure is a tad immersive.
