Over the previous several weeks, I removed the old carb rack from my cb750 (not an easy task) and also removed the airbox which I discovered to be a fascinating piece of engineering. 2 crankcase breather hoses attach to the airbox and shoot any solid particles (water/oil) to the back of the airbox where any condensate drains down to the catch tank. Remaining oily air/fuel mixture is then sucked back into the engine for burning. (I wonder how this recycled mixture affects octane rating or if the claims that this mixtures adds to carbon build up in the intake tract has any merit). Picked up a heater hose from the local auto store and cut it into 2.5" straight sections to connect the new carbs to the engine (3" would be better to allow space for cuts). Since the carbs do not line up perfectly with the engine you must make some angled cuts on the connectors to get them to mate up with the carbs. My #2 connector was a little short and I will need to go back and make another o
