I've got at least 500 miles on new RT fork springs. I've been up and down the range as far as external adjustments go at what seems every possible combination in 1-click increments of Preload, Rebound & Compression. Countless hours of online research. Overall the ride is good, but I think the ride @ 70mph on So Cal freeway slabs should be MUCH better than it is. Probably the best thing I've done is put on a new front tire 1/2 way through the process and now I feel like I'm getting accurate feedback.
Symptom - it is NOT harsh and it is NOT plush, but seems very busy (opposite of an old Cadillac) on the freeway slabs. From what I gather, that indicates too much rebound. At this point rebound is dialed completely out at 32 clicks (arrived there by 1-click increments). Seems like the best setting so far but doesn't sit well with me logically & the ride is not where it should be IMO.
Fix - I thought with no more external adjustment I'd go internal & decrease oil height to 130mm (from 110mm, coincidentally Traxxion rec. 150-160mm !). Louie at RT says this will have little affect. He recommends increasing preload which will speed up the spring action & make it feel "softer." I thought increasing preload makes it firmer? I also understand that if you "increase" preload, you will have to increase rebound and I know increasing rebound makes the ride firmer. He's says that they've had good results with rider sag @ 35mm too. Most what I've heard on this forum (and Traxxion) is 38mm-45mm.
Question - now what? Is Louie correct, do I need to start again with more preload? Should sag be @ 35mm?
Particulars -
42-45mm rider (dynamic) sag (equates to 3rd - 4th line of preload)
110mm oil level from top
US-1 2.5-5wt oil
.90 spring @ 175 lbs
Compression set at 16 clicks out seems good without excess dive (most rec. 12-15 out)
TIA
