NEWER UPDATE: The hose barb that dumped all the fuel out would connect to the evaporative emissions control on a California emissions-equipped bike. Page 5-6 in the service manual shows the way the hoses should be setup.
UPDATE: There were no hoses missing from my 49 state 1989 Pacific Coast. I am told that it is supposed to be this way. And the bike runs just fine. Check out this thread and this post from the IPCRC for more information.
This morning while I was pulling the carbs off my bike I noticed what appears to be some missing hoses. In fact, one of the bare hose barbs even dumped a bunch of fuel out when I pulled the carbs off. Anyone know if there should be hoses on these barbs and where those hoses should go? The bike has run just fine since I bought it 1000 miles ago. Maybe I should just let sleeping dogs lay?
My finger is pointing toward a bare hose barb. It is open to the other hoses. When I pulled the carbs off, a bunch of gas dumped out of this barb. The hoses that branch off from this barb go to both carbs. Update: that weird T thing is where all of the vacuum hoses come together on the carbs.
Another view looking from the right side of the bike. There is also a barb with no hose on the plastic part where our trunk release and gas cap live. It is visible on the lower front of that assembly (the left side of the photo). It is in front of a brown hose with some condensation on it. It is the same size as the barb on that multi-T thing which is at the same height in this photo and just to the right of center in the picture.
This is looking from the right side of the bike. My finger is pointing toward a little metal tube that comes off of the carb and goes into a rubber hose that appears to be broken off. Is that supposed to be that way? Maybe it’s just a plug or something? The carbs are several blocks away (internet is out at the house) so I can’t look on the other carb to see if there is a similar setup or if it is unique to this carb. Also can’t tell you if it is a plug or open. Yeah, not to prepared this time 🙂
