Basis Vector 4 arm question


Hi all,first post here,appologies if this has been asked before.
Re the silicon arm damping,I followed the instructions and filled the well up to the bottom of the radial bearing, however I read somewhere that the level can be adjusted and this will alter the sound,has anyone any experience of this and what are the effects.
cypry
Anyone knows the viscosity grade for the Basis Vector 4 tonearm ?
Have written to Basis to purchase the damping fluid but yet to receive their reply.
Hi,
One of my friends just bought a basis debut used here on Audiogon. He overfilled the sillicon too much. Now the sillicon is all over the tonearm ball bearing assembly. Is there any effective way to get the sillicon out of the bearing?
thanks
