Ok so I bought the GS1100 last November from the owner who last rode it in 2005 when it developed a noise in the bottom end that be chocked up to being a bad main bearing as his uneducated guess.
I picked it up for 300 dollars in a filthy state of being covered with a tarp outside all these years. I researched the bike and famous clutch rattle before I even gave him an offer and have been hoping all along that's all it is.
Finally the other day I decided I had time to check it out, removed the gas tank full of old fuel and stuck fuel petcock and hooked up a makeshift fuel tank. A couple shots of starting fluid and it barked to life.
After a few minutes it was ready to idle on her own. At idle there is definite rattle and pulling in the clutch makes no difference but raising the rpms just a bit and it smooths out.....its a pretty ugly rattle.
So....I pulled the clutch cover and found the clutch hub nut loose and 3 of the 6 damper springs loose to where you can play it as a tambourine in a band. I was pretty sure I found the problem so I tried to put a band aid on it just to prove that was my noise. I spread the springs much as I could with a flat tip screwdriver and tightened them up quit a bit and assembled everything with 40ft/lbs on the hub nut. Again just to rule it out, I will be ordering the APE heavy backing plate/springs/rivets and doing it correctly. So buttoned back up and it may have gotten a little better but the majority of the noise is still there.
Next I pulled the other sides cover to get a look at the starter clutch. I dont have a flywheel puller and of course either does the dealer in my area so I will have to order one. What I can see is the 3 bolt ends coming in from the back of the flywheel 2 of which are almost backed out....3 one is some what loose as well. I can move the starter clutch somewhat independent of the flywheel and there was a little bit of metal filings (not an ungodly amount) on the flywheel magnets yet I cannot see anything bothered up from around the sides with a flashlight that stands out. So I know I need to get in there to see what's what and tighten everything up but what's the opinion while I wait for a puller to get to Alaska in the mail? Would this cause the bottom end rattle I'm hearing? I took some videos but not sure I can get em on here but I'll give it a shot.
