I took apart the bike after a coolant leak and discovered two hoses, on on either side of the bike, open to the atmosphere and just sort of hanging down. Not sure if these are where the coolant dripped from.

I have not yet been able to identify where these hoses are supposed to connect to. I have studied the manual, diagrams, and fiches, but still not sure.

Attached is a photo with the suspect hose circled.

 

Looks like a f2 engine or cylinder head. F2 s have a vacuum. port right there that connects to the petcock on the fuel tank. The cbr 900 also has the same vacuum port on its petcock. hope this helps . maybe previous owner did some head work or maybe swapped out heads and tank. just a thought.

 

Appreciate the response!

I don't think these go to the petcock. The petcock only has 1 connection, and that's to the fuel pump. The fuel tank itself has two connections, and I know where those are as they have mounts to them.

P.S. Because I didn't get a chance to take out the air filter housing yet, I opted to grab a photo of someone else's bike online that showed the suspect hoses. Not sure if it was an F2 or an F3, but the hose set up in the photo served the purpose for this post
