RT Gold Valves or intiminators?
OK, I am trying to improve the fork performance on the rough/gravel/forest roads. It is 650K7. Last year I enlarged damper rod compression holes up to 9 mm in diameter, cut off 2.5 coils from the straight rate part of springs, put in new spacers accordingly, and went for 7.5 wt oil. The job done made big difference. But I need an improvement. Now, riding over a big obstacle, more than 10 cm in height, like a speed bump, generates front jump to the height of that obstacle. The good fork would absorb the obstacle for its effective compression travel, then the motorcycle would raise, if the obstacle is higher. Mine obviously does not. It is either the spring rate is too high, or, despite enlarged compression holes and thinner oil, it hydraulically locks. I tend to believe it is the hydraulics, hence I am after the new valves.
I understand how do RT Golds work. And I am not afraid of taking the fork apart once again to drill some more holes required. What holds me off is the owner’s opinion. I heard from guys who do know what they talkking about that despite different valve springs, preload, and various oil viscosity tried the improvement they achieved was still moderate. The same story is true in regards of intiminators. But here I have something else, I do not understand how do they work, what physics/hydraulics involved? Does anybody know? Does some explanation/schematics published? What would you prefer, RTG or intiminator? I read their comparison, but it was based on one guy experience, one guy does not make statistics.
