Richie-Van-GTi 71 2 Cars Posted October 25, 2006 does anyone know or can measure the spacing on a twin 40 weber manifold? Ive decided to go for it with some bike carbs again as I sold my last set. Wondering if I can get hold of a twin 40 DCOE mani and adapt it to take the bike carbs as bogg bros is a ridiculously long waiting list at the moment. If anyone has one kicking about it would be much appreciated. Share this post Link to post Share on other sites
PumaRacing 2 Posted October 25, 2006 The barrel spacing on a DCOE or Dellorto is 90mm. The spacing between the inner barrels of each carb on a twin carb manifold depends on the manifold/engine but is usually between 95mm and 105mm Share this post Link to post Share on other sites
Richie-Van-GTi 71 2 Cars Posted October 25, 2006 is that 90mm between each barrel or 90mm centre to cenmtre if that makes sense? I need to matchthe gti head spacing to the carbs which are 40mm barrel with 40mm space between each. Share this post Link to post Share on other sites
