Tubes from carburator

Postby Lars_Erik » Sat Dec 30, 2017 3:38 pm

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?

Original they did go to the airbox. They go to a T then to the airbox.

mean and that I need part 16180-460-771 and 17231-460-730 or equivalent. Does that make sense?

thats the connector to the crank breather I think. The carb vents should got to the plenum box. The box right behind the carbs
