Question for the fork experts

[Gomes-nz]

Someone out there will know the answer to this question.

I have a 1991 KDX200. The front fork has a dampening rod in it, which has 3 large holes drilled into it at the bottom and 2 small holes at the top. What affect does each of these have on the fork action, and why. Will these affect the plushness of the fork.

If I add thicker oil, is that affecting the compression or rebound damping .....

The racetech web site has a great article on dampening-rod vs. cartridge forks. The orifices in the dampening-rod forks are explained in detail along with the effect oil has on them.

Thanks. I checked the race tech website and i now understand. I think I need an emulator valve. Seems to be the way to go.

You don't need an emulator. You can have the orifaces changed. FRP can perform this service. Give them a call for details.
