I was doing the first oil change and pulled a ply I thought wa the oil plug, left hand lower case. It had a funny looking spring behind it! I wiped it off, reinstalled it with the skinny end of the spring up and went and found the correct oil ply bolt and did the oil change.

However, now I am afraid to start the engine without knowing what damage I might have done by removing the wrong bolt with the spring, what is that bolt and spring?

Yes, I know, stupid, and I am a professional mechanic to boot. But I wear tri-focals and I mistook the bolt stupidly, it was totally obvious it was wrong, real dumb.

New Monkey 125, 100 mile oil change. Sorry to barge in unannounced, hope y'all will not be angry with me.

Thank you,
J

You're good dude. Just popped out the timing chain tensioner spring bolt. Provided everything went back in, and in the same order, you're fine.

Thank you. The only thing that came out was a long spring with a large end and a small end. I put the small end in first which is the way I think it jumped out and the bolt has a groove machined in it which appears to be made to accept the large end of the spring.

I was afraid it might be a oil pressure poppit and there might be a ball or something that ran away and hid. The only thing, like I sad, a bolt/plug and a spring, arrrgghhhh! What a dum move for somebody who has owned motorcycles for nearly five decades..

That makes sense, I am not so worried now.

Thanks guys for all the help. Yes, I have a manual ordered. It was not because I did not know which plug was the oil but I am blaming it on my new trifocals. I looked under and saw the plug, then put the wrench on by feel judging the distance but the magnification messed up my "feel" and that is my story and I am sticking to it dang it. So as I turned the plug out, talking to my wife, the warm gush of oil never came, only a spring that shot off into the empty oil pan and then bounced around the floor. Most surprising I shall say and not what I expected at all. All seems well and the Monkey is back to doing monkey business.

I also discovered this parts site with good diagrams:
