    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

First post here, and I have a problem. I've searched about, and am not sure what my issue is.

I have a 85 GS550EF that is making a knocking sound. I've only owned the bike for a few months, and am not really sure if it is a new sound or not. I've been paying more attention to it since my R/R went, and I boiled the battery dry. Anyway, I've pulled, stripped and re-wrapped the entire harness, installed the new R/R, and am now noticing this knocking (only at idle). I'm trying to include a video here (1st timer), and you can hear the knock in the second half. Any suggestions greatly welcomed!

Whoa whoa whoa...least buy us dinner first! :p How about a little introduction?:)
 
Clutch, starter clutch or cam chain tensioner are the usual suspects for funny noises. Not sure on your model though.

Nice looking bike.
 
I enjoy sea-food, cinema, long walks in the evening, and motorcycles that do not knock.

Thanks. I am a complete noob to bike mechanics, but am mechanically inclined, (and employed). Still learning. There is no change in the knocking when I work the clutch, is this sufficient to eliminate that do you think?

Lol...funny guy..must be Canadian. Where in Canada are you? I went 27 years between GS 750s. Soon discovered I wanted a bigger bike, hence the 1100. Careful, these bikes have a tendency to multiply.:D

I'm in Edmonton, found the bike down in Calgary. It was sold the second I heard it run, it was like I had never sold my 83. Heh heh, wonder if it was knocing then too :eek:

Not always. It's very easy to take a look inside the clutch. Don't even have to drain the oil. Check the big clutch hub nut, they come loose sometimes. Then pull the clutch off and look at the springs in the back of the basket. They tend to get loose from sitting compressed 30 years.

You do have a service manual?

The starter clutch is a little more involved.

I do have a manual, and I've been through what looked to be an excellent thread here on doing just that, (I think you may have commented on it). I'll get in there and have a look. As far as not draining the oil, is it just leaning the bike over and supporting it somehow?
 
Sidestand works fine. The oil isn't that deep in there, it will all go to the downhill side. The clutch cover will drop a few drips but it won't spill. Unless it's WAY too full.

Thanks for your help, just read the procedure in the manual, looks as though I'll need to pick up a few gaskets before I start. I'll post back with results.

Sometimes the gasket all comes off in one piece. Sometimes not. It depends on who worked on it last. (if ever)
 
Ok, been awhile, but I finally got to this issue. I took the clutch apart and inspected everything, all was within spec. I serviced the cam chain tensioner, seems good too. So now I'm headed for the starter clutch. When I had it running, doing the block of wood-stethoscope method, the sound was loudest on the left side, near and on the generator cover. Here is what I am seeing so far......is this gear supposed to have this much play? (click for video)
