Hey Doc I've asked you about these before... I'd possibly be interested too if you decide to make them. I spoke to Russell Eng the other day about their stacks. Which would you recommend as the better option, your stub stacks with the ramflo or theirs with a sock? How effective is a sock as a filter? Is there any risk of engine damage?

Socks are good, if you have room. I don't..
Graham's stacks won't fit a Dellorto without mods. They are a little longer too- probably too long for a Ramflo filter.
We dynoed Baracade's 1380 road motor at Xmas- has 45DCOE, 286 cam, we got 110HP with Graham Russell's stacks, 110HP with socks on 'em. Made no difference to power.
For a road motor, I would oil them- for the track many leave dry, or just spray them with WD40.
