My Ryca RR-1Bobber ( Suzuki s40 base) developed a small oil leak from a part I cannot ID. It looks like a small silver reservoir next to where the clutch cable connects to the transmission.  Once the bike is hot this opening bubbles over and runs down the underside of the engine, making a mess of my parking space.  Can anyone ID this part for me so I can start working on it correctly?  The attached JPEG is actually three photos. I hope it helps. Thanks..

Brother, that makes too much sense!   Between my military deployments and family time I spent years building this RYCA bobber.  As a guy knew the mechanics I had forgotten what went there.The moment I read your reply, I smacked my head.  Thank you very much!
