Clois,
LOVE 'EM! Had to go back to the single four to do some troubleshooting (not 2x4 related), can't wait to put the 2x4 back on! I'm running 2x390 cfm carbs so can't comment on jetting for your 650s. I ran a 1-to-1 linkage setup, but I think I'm going to try a progressive when I get it back together. Mine seemed to be a little rich out of the box, apparently a common comment from 2x4ers, but it really ran well...and the looks are the best thing of all.
