It’s none of these it’s directly below the tank on the front brake side there are two they are Allen wrench flush with the bottom of the engine block. They are not the other ones I know all that I change the oil all the time and the tranny fluid they are and they’re really good. I am a snap the Allen wrench trying to get them off so I left them can’t find out what they are. It’s further up from those plugs. You are showing towards the tire front tire but definitely on the bottom of the engine block. Looks like some kind of a sump drain.

It’s directly below where you take the case off to get into the cams and the oil pump right below it. There’s two screws on the bottom of the block.

Unless you're trying to figure out if your engine is sumping, leave those plugs alone. The opportunity to really screw up something expensive is great.

That 1/4" Allen head plug on the bottom of crank case is for the sump. Do not remove that unless you're checking for sumping. Then if you have to remove it hit it with some heat first because it has some tough thread locker on it. Make sure when you install you use some red loctite and do NOT over tighten it or it ruin your life...ok not your whole life but the next few weeks are gonna suck. Theres a chance of cracking the case because it's a tapered pipe plug and if you ram it home it could get ugly. Who ever posted that drain plugs for dummies is the dummy because there's at least 2 plugs that are mis- labeled. You're asking lots of questions and doing lots of research here...thats good ...thats what the sites for but you should get yourself a genuine factory service manual. And you should apologize to Mr. Lonebone...its the right thing to do.
