With the comp jets installed and an FD regulator you should see 30 psi at 1000 rpm hot which is plenty.

The comp jets and the Weber jet are pretty much the same size. The Weber jet just fits inside the stock jet. I'm not crazy about paying the same amount for another part that presses inside something in the crank shaft, so I use the comp jet. Both actually have a smaller orifice than the stock jet. I guess the idea is that with the ball and spring removed they have the same peak flow and still have constant flow.

Also, did some playing around yesterday. The oil pedestal o-rings are a good match for the S5+ front iron. You could possibly use one of those in place of the teflon o-ring/small o-ring combo and do like we do with the earlier engines that don't use the teflon piece and simply omit the front cover gasket in order to squeeze the o-ring a little tighter. The oil pedestal o-ring has a little larger diameter than the regular front cover o-ring as well so you should get plenty of grip on it.
