Hoses from the stock clean air system attached to the left side air suction valve cap and to the right side air suction valve cap.
An air suction valve is commonly referred to as a reed valve.

I don't know what you mean about 'popping'. The reason I got rid of mine is because I didn't like how it looked and I didn't want the additional complication on my bike. All the system actually does is bring in fresh air to mix with the exhaust so that it would pass US emissions requirements. Kind of funny how it worked...same amount of exhaust in the air but the government was happy because it didn't come out over a certain percentage. LOL
Imo, whether you plug them or connect the two hoses together like you did, won't really matter.

I noticed that hose doesn't connect directly inside the airbox as well. So leaving the connection into the bottom will keep it open like you and patton recommended.

Thanks for confirming that the hose doesn't connect directly inside the airbox.

Can I use a brass brush to clean off the leftover sealant around the carb holders or will it damage the mating surface for the new ones?
