Does anyone have the dimensions of the Honda CB750 carb inlet rubbers (the diameter of the hole at each end)? Particularly those fitted to the CB750 F2. I'm looking for a set of rubbers for a set of Keihin race carbs with ticklers (CR31) to attach to a K0-K6 cylinder head. The spigot on the carbs measures 40mm and surprise, surprise the rubbers for the K0-K6 models don't fit.
Thanks
Eric
