Look what was in my sump (should i be worried)

[Guest]

I took of the sump today to clean the screen and this is some of the stuff i found inside





do i need to take the whole motor apart and expect a major damage

As the old saying goes..if you have to ask, you already know the answer.

the black thing looks like the end of one of the timing chain "cushions"
the metal part looks like a piece from a cooling fin

Hi,

Oh, I don't know. How has it been running? That looks like bits and pieces of gasket, maybe a little corner of the cam chain guide, small rocks and dirt? Those bits that look like metal seem to be a corner broken off of something internal and are not serious. If it's running OK I wouldn't worry too much. It looks like the sump screen and oil filter are doing their job. Maybe a previous owner was careless when he had the engine open and dropped a mess into the bottom end. I don't think it's critical to tear the engine down right now. These engines are pretty tough.



Thank you for your indulgence,

Thing is this...you wont know for sure, what its all from until the engine is opened and inspected..I was thinking cam chain guide and possibly a clutch basket tooth or something..along with chunks of clutch fibers.

[chuck hahn]

Cliff..if you saw that in your oil pan..you mean you wouldnt tear it down and find out why?? Thats doesnt sound like you mode of operation at all. I am surprised at the answer.

Thanks guys

Hi,

Yep, it never hurts to be sure. I'm just saying that *I* wouldn't worry about it. But then I'm pretty lazy.

I guess I would at least inspect the clutch, look under the valve cover and stator cover, etc, to make sure everything there is OK.

How big are those pieces? There's no scale. Smaller than a dime? I guess they don't have dimes in Israel.

I gotta go. It's time to adjust my valves.

Thank you for your indulgence,

This is what happens when you go looking for problems instead of letting them find you in their own time.

[greg78gs750]

wow, that's a lotta stuff. how does it run? if it has been running, it probably will keep running, and i would go with cliff on this. depending on your budget, timeframe, and end goal....

[JEEPRUSTY]

The screen is working at least.
Wanna throw a dime on the pics for reference?

I think this is what happens when a flywheel filled with magnets, epoxy and other great things go



Pull the stator cover and look at the magnets.

That little aluminum tab looks like part of the cover that helps guide the wires around the outside of the cover.

In the second picture your black part looks like its part of a magnet. There is a few pieces that look like resin on the magnets.

There is a gasket part in there.

And those long pieces could be from an O-ring that sits under the barel's.

Pull the cam cover off and take the timing chain tensioner out. Then take the intake cam out.

Move the chain out of the way and try reaching down and moving the chain guide. You might even be able to see enough of it to see if there is any damage.

WOW, Don't know bout u all but if I found all that crap in my screen I would be looking for a backup engine as I was tearing this one down to see what is up.Rather have it apart than ride it with gobs of crap missing from major internals.
I mean not to scare you, but a bike that old and only doing plugs and fuel and oil,That's your first mistake, These old bikes ran forever and were treated as such, getting neglected, Didn't you get the mega welcome and the GS deadly sins tour?
This is a a joke right? April fools past didn't it?

[eran_k]

I'm going to open it one way or the other, for inspection and timing chain replacement.

[sedelen]

I fall into Cliff's camp.
If the engine has been running good, I'd just press ahead and continue to do what you were doing. I'd ride it locally for awhile until I regained my confidence in it. That chunk of metal would probably be my main concern.
I'd be looking at the outside of the engine for a missing fin, but more likely to be found underneath the valve cover.
