I just bought a 1999 gasgas 300ec first dirtbike.I hoped on it and rode it a couple hours. I was researching how to change oil and i see this. Its just a hole no screw or threads but the side of tank looks black like its full of oil. I don't even see the 2nd hole to drain crankcase. I looked on forum can't find pics.
First gasgas think i screwed up

it should be the allen head in your picture.. not the open hole cannot tell which is the back of the engine.
kinda hard to tell in the picture but look thru this thread there are tons of good pictures of those motors apart, yours may be a little different, bt close enough to figure it out...

And if it doesn't answer your question yo have just ridden a bike without oil (for ages) and it didn't blow up !! ... that is reliability, be happy����

The hole with no screw is a vent hole....should be just like it appears....nothing to worry about. I asked the same thing on a different thread.
For the guys who quickly chip in and respond to these threads....thanks. Ive been riding street bikes for many years but this is my first off road bike....confidence level is low so when I ask a newbie question and guys are more than willing to reply it makes a big difference.

I would suggest taking the cover off and looking in there for corrosion on or around the stater. If the hole is plugged with mud moisture could be trapped in there and corrode parts.

Correct.
Washing it would have been a good start
I wouldn't even think about buying a plugged up bike like that.

That is cheap as hell! Good deal there even if it needs a full rebuild!
Great deal! Congrats!
At your earliest convenience you should try to remove the swingarm and service the bearings. This is often the most neglected part. Hopefully it's not too late.
If it is "too late", then you'll be faced with a major hassle to get it apart. Or you may decide to leave it as is (since you only paid $450). Check it out, though. You may get lucky and be able to "save" it.

I did this to my '01 XC200 when got it. It was way past due, but all parts were still usable. Worth the time and effort, highly recommended.

You need remove the swingarm to check the bearings and seals. Since you have it apart you should service or replace them. The seals can be replaced with o-rings (on most models).
If neglected, the bearings can seize and cut grooves into the swingarm pivot bolt and render it almost impossible to remove. Hopefully yours isn't that far gone.
It's not a fun job but anyone can do it. Remove the linkage and lower shock mount and anything else attached to the swingarm. Then drift the bolt out (being careful not to damage the threads). It often helps to loosen the rear motor mount as this can sometimes be putting pressure on the frame at the swingarm bolt and cause resistance.
Best of luck to you.
This applies to all bikes, btw. I had an '84 XR500R that the bearings had grooved into the bolt and it would not come out, even with pounding on it with a big sledge hammer. I had to cut the swingarm and bolt off and replace them.
