I see this is an old thread but I thought I might add my experience with the 642’s
I’ve complimented my Wilber’s 642 nightlines with racetech fork springs and valves. Static sag is set at 35mm for two up with spring length compressed to 150mm. Solo settings are 35mm sag with 155mm spring length.
I’ve tuned the high and low speed dampening to improve the ride but I found that setting the correct sag for the load is a game changer for performance.
My 642’s are standard length and it’s not unusual to drag the roadster pegs from entry to exit through sweepers (or any other corner)
I had no chicken strips with the stock suspension and now I’m finding that I probably need to change my corner technique.
I have a cobra chrome on the front an an exedra max on the back.
