I am rebuilding an CB650 SC 1982 and have a question about the two tubes pointing up from the between carb 1-2 and 3-4 carburetor. They are coming from the three way joint between the carbs. I have a US model with crank case breather hose so the connection on the air box is already taken. Are they drain tubes or shall trey be connected somewhere?
