400 carbs?
« on: January 10, 2011, 10:35:30 PM »
can anyone please tell me what size carbs were fitted to the 400s?a guy wants to know if he can fit a set from a 500 to his 400,i told him the spacings would be wrong etc,or can the 500 carbs fit on 400 runners?

CB400F carbs are 20mm Keihin (same size as the CB350F).  The carb throat center-to-center spacing is narrower than the CB500, so it would be difficult to adapt the CB500 carbs (which I believe are 22mm).
