Secondary oil change question

[Guest]

Working on my $300 1981 GS650 GLX. Took off the secondary cover, drained the oil, and can't seem to find where to fill, or the level hole. It's really obvious on my Cavalcade. I looked at Cliffs description on this, but that is for a GS850, not the same. Any help would be appreciated.

Should be on the top & I believe you fill till it runs out...

Thought the 650 secondary gears were lubricated by engine oil?

I'm a total newbe to this bike. I pulled the drain plug and got 6-8 oz of what seemed like gear oil out.

The final drive uses gear oil but not the secondary gears.

Section 2-11 in the factory manual describes the oil change procedure, including the need to remove two drain plugs. One on the sump cover and the other on the LH side of the engine by the shift lever, which drains the secondary gear cavity.

Thanks. I ordered a manual from Ebay. I think the oil looked like gear oil because, God knows how long it's been in there!

Basscliff has a free manual download (in case you didn't know).

Yep, two drain plugs but only one fill hole on the 650s.

Confirming that 650g doesn’t have separate lube for secondary drive, it uses crankcase oil. One of the things unique to the 650s from other GSs.

i had 650g for years before getting 850g. Then it took a while before I noticed the fill plug on the 850g.

My policy has always been that you should learn something new every day.

After you learn that new thing, you can go home.




The boss didn't always agree.

I have a fear that for every day I learn something new, I forget two old things.

That's OK, the 'new' stuff takes more memory.

"Working on my $300 1981 GS650 GLX. Took off the secondary cover, drained"

what secondary Cover? As others have mentioned, there is a second drain plug at crankcase bottom just inside of shift lever that drains out of the secondary drive cavity. And it gets refilled from crankcase...it just leaks thru.
