Jaybird180 Posted April 8, 2017 Report Share Posted April 8, 2017 My theory is that the top out spring in my 2006 CBR1000RR fork is not only progressive but it's variable.Full range of travel yields 16mm of preload adjustment from all the way out at 0 to full stop.At full out, the installed preload was measured at 8mm. At 6 turns it's at 9mm and at 12.5 turns it's at 15mm.Someone please explain to me what's going on here. Aftermarket springs are 260mm, stock was 217mm (from memory). The preload spacer was cut from 100mm to 73mm 1 Quote Link to comment Share on other sites More sharing options...

Jaybird180 Posted April 11, 2017 Author Report Share Posted April 11, 2017 Does he show up on the forum? I've been in communication with him about a week ago about this. He referred me to a YouTube he did which in turn referred to a Ustream video. I am watching Ustream now. Quote Link to comment Share on other sites More sharing options...
Jaybird180 Posted April 11, 2017 Author Report Share Posted April 11, 2017 It doesn't make sense for the rate to change because it's a thread that moves. It should be linear but it wasn't (as measured with the fork apart). Quote Link to comment Share on other sites More sharing options...
Jaybird180 Posted April 11, 2017 Author Report Share Posted April 11, 2017 He just got back to me, said I need to take sag measurements and that will help determine if something is indeed awry. Quote Link to comment Share on other sites More sharing options...
