First, to NancysToy ... Indeed, buffeting and wind is an ever-present factor. My only point was, despite the fact that the Elkas ride beautifully, I don't think they pre-loaded mine enough to actually mitigate the roll factor better than I had on my stocks. Therefore, my intent was to research the best way to tweak the pre-load and/or the rebound to mitigate the effect as best possible (which I'm sure will culminate in a flatter ride than my stocks).
Today I had a great conversation with Sebastian at Elka Suspensions. I described my observations (in context of the previous thread entries), which revealed the following information (Note -- I am only addressing Stage 1/Stage 1 Plus shocks here; not Stage twos and beyond):
First, going back to spring length. The actual 'factory' uncompressed spring length is 9.5 inches. Elka advises against compressing more than three inches below that; meaning not less than 6.5 inches. Mine came from the factory compressed to about 8.5 inches; therefore I've got two inches to play with. Good.
Second, to optimize pre-load firmness and mitigate roll on a single-stage Elka, the formula is two full turns downward on the pre-load (top) ring, and three clicks in (up) on the rebound setting (bottom of shock). For every two turns, three clicks, and so on. This formula would apply in reverse if one were trying to achieve a softer ride and more rebound.
Again, Sebastian did warn to not over do it on compressing the shocks and tightening rebound as it will (of course) result in a harsh ride. At any rate, I found this information extremely useful and I'm looking forward to setting it up on the bike.
To Tonga's question: (1) There is a dampening adjustment on the reservoir for the Stage 1 Plus's, but I would be very careful messing with it, if at all. It is set at the factory, and did not enter into the conversation I had with Sebastian (above). On the Stage ones, the reservoirs simply act as a holding area for heated shock fluid as it expands through aggressive twisties. Adjusting it would only affect the rate at which oil flows between the shock and the reservoir. On normal ryding, they shouldn't factor in much. On 1-Stage shocks, the only 'end-user' adjustments are the pre-load ring and the re-bound setting. (2) What does Stage 1 mean? "Stage 1" means it is a single-phase system, no crossover function, adjusted for both pre-load and rebound. Stage twos have a two-stage system separated by a crossover spacer to achieve a progressive ride between preload and rebound (somewhat splitting spring function between preload and rebound), in addition to the pre-load and rebound adjustments for ride firmness (page E15 of owners manual). (3) Elka Shocks come with all parts, adjustment tools and instructions for installation.
Good luck with your install and I hope this provided useful information.
