Which Reed Valve?

Featured Replies

Hello. I recently bought a 2000 cota 315r. The bike currently has a stock reed block installed with some sort of carbon fiber reeds. Looking closely I see that 2 of the 4 petals have a short nylon tensioner, and the other 2 petals have a longer tensioner. By "tensioner" I mean a small flat nylon rectangle which is about the same thickness and width as the reed petal, and is about 5mm-10mm tall. It installs between the petal and the reed stop.

The bike also came with a Delta VForce-2 reed valve still in the box. Previous owner never got around to installing it. So my question is: since I've got the bike apart at the moment, should I go ahead and install the Delta Force reed valve? If so, then which tension setting should I use? What can I expect from this reed valve? I should mention that I'm just starting out in trials, so smooth and manageable low end is preferred.
