second drain plug not draining?

[timebombprod]

oil level is over full before i start it, still not starting till i make sure this is okay, i was trying to drain some oil from the second drain plug near the shaft drive and nothing came out,is it because the engine hasnt been on and oil hasnt reached there yet?

Isn't that drain by the shaft for gear oil in a separate compartment.

[salty_monk]

Yes, it's separate oil in a separate compartment & should be filled with 90w hypoid...

wat, i beentold it was a seconddrain plug


thats why mine takes more oil than a chain drive, right?


its right under the transmissioin

[salty_monk]

Maybe the 650 is different but all the other G's have a 2nd oil compartment..... and yes it's a second drain plug for a separate compartment that uses different oil.

This ring any bells? On an 850G http://gsarchive.bwringer.com/bikecl.../bevel_oil.pdf

Let's see.

You have the factory service manual, right?

Yet, some random person "told" you what it was

Yeah, I'd go with the random person

okay shoulda just checked my manual.....while i was right i guess i was wrong second guessing myself, just tryna be careful. just weird as to why no oil is there but its cuz my engine hasnt ran i suppose

I’d guess that the second drain hole in your pic is above the level of the drain plug in the bottom of your oil pan. So if you took the oil pan plug out first, maybe you’d see little to no oil come out the higher drain. I looked in your manual, and I believe you’re right, it does appear to be a second drain for engine oil. I find this very strange, never seen an engine with more than one oil drain hole. But I’ve only owned 5 different bikes and am no mechanic.

make sure you have new crush washers (Suzuki calls them Gaskets) for when you re-install both of those drain plugs. They are single use, at least I’ve always treated them that way. Others may reuse them, I won’t.

No, NO, NO!!!!

That is indeed, a second drain for ENGINE oil. It is unique to the 650.

Do NOT use 90w hypoid gear oil.

I have never tried it, but I would GUESS that if you have not run the engine after filling with the proper amount of oil, there is a POSSIBILITY that there might not be much oil in the rear compartment. I am not sure how the oil gets into that compartment, it MIGHT be pumped there by a running engine. Since you haven't run the engine, there MIGHT not be anything in there.

Sounds the same as the XJ900F - the front bevel drive oil is actually shared engine oil with its own drain plug. Ideally, to perform a full oil change both drain plugs should be undone, but meh. There's never much comes out of the bevel, so if it's forgotten about it's no biggie. The bevel drain only gets the last few mils of oil out, so compared to the quantity of a fresh fill, it's negligible.

Everyday is a school day I guess
Got me thinking about that engine oil leaking into the box on the 850.
