Tube under alternator

Postby gocubs1 » Sun Mar 14, 2010 10:02 pm

Hi! New member here, and thank you ahead of time for the help. I have a 1989 GL1500. There is about a quarter inch diameter tube with a rubber cap just below the alternator on the left side of the bike. I thought this was a grease zerk of some sort, but in looking tonight I see it is not a zerk. I do not know what this is for, and am wondering if it's something that requires maintenance. I do have a Haynes manual for the bike but cannot find anything on it there either.

Bleed valve for clutch.

it could be the drain plug. Does it have a removable plug on the end, if so drain any condensation from the plug, and put the plug back.

There are actually three rubber hoses hanging down, two of which are supposed to have a drain plug at the is for the crankcase breather, the other for the clutch bleed valve......just drain at each couple of oil changes...not much fluid comes out. The third one is the battery overflow tube (not to be plugged, ever).
