The top face of the Emulator has nine areas,, Three of which I've filled-in with copper square rod , held in place by soldering. These small rectangles extend over the oil flow path which is above the lower check valve ( rebound valve ).
IMHO the manufacture is going about the tuning of its product to an application within certain limits.... and its OK,, nothing really wrong......
RT concentrates on the pop off ...which IMHO is what we want the least of, ( compression ) ,We want the most compliant fork action on the " Hits" as possible....More holes in the pop off and lighter fork oil, and of course less pre load on the pop off all work to gain a smooth ride...But,,, at the loss of rebound dampening........RT may recomend a lower rate fork spring to tune their product to a certain application,,,,,,,this may be OK for riding up hill,and on the flats........Down hill is the test,,,,,combine with a irregular road surface and braking,,,So IMHO the first consideration is the spring rate to support the vehicle and rider.....At 180 lbs...I tried .90..but came back to 1.1
Back to Emulator........I may keep adding more to restrict rebound..and at the point of too much...drop back to 10 wt. oil and two holes in pop off..........I'm trying to dial in what normally can't be changed....then fine tune the pop off.....I think a better ride is in the works !!!!!!
