Change oil Plug Looks Funny

[snyper316]

Ok I changed oil in my vehicles yesterday. When I got the Motorcycle I noticed that the Plug has like a screw in a nut looking thing, but it would appear that there is maybe supposed to be a flanged bolt of some sort. Does anyone have there oil pan plug to where they can take a picture of how it is on there bike. I should have took pictures of what mine looks like, but last night I was so frigging oily I wasn't about to touch anything other then the computer that I have set up in my garage. All I have to say is it looks crazy!! I don't know if this is the set up or not. I also found out our Wal*Mart don't like motorcycles no more. All I could find was something called Quick Silver 20-50w oil. They used to have all kinds of oil for motorcycles. They also used to have all kinds of Motorcycle acessorys like my Blue lens glasses which were actually Orange in color.

That is what the stock plug looks like, at least my 88 has that same plug.

I never looked it up in the manual but my only guess is that the screwdriver is for tightening so you don't strip the threads, and the hex is for getting it out when it is over tightened. But that is a purely a WAG.

Yeah I don't know if it is a stock tool but I used the 19mm flat wrench with a bar with a flat end that fits perfectly over the wrenches, to break it loose, I snugged it back in and so far it isn't leaking. Now for that filter mod come spring time cause it was PITA trying to get the O'ring to stay cause it kept curling up on me. So my question, is with the oil Filter mod on there does that do away with the cassette holder?

In the book it shows a simple plug with a copper gasket washer. That is why I was asking in the first place because it is the first time I have ever seen this kind of setup. Then again Most of the work I have done has been cars and scooters.

My '83 has the same oil drain bolt as yours snyper. I thought it odd too.

Yeah I'll admit I was trying to figure out how to get my big headed screwdriver cause it's a long one. So I looked on Yamaha parts house and found I should be able to loosen the big nut!!

 

Twist the handle and move!!!

I think that screw holds the magnet??? Maybe??

Ditto, that is what it is for.

It is my understanding that Yamaha used that screw for a temp sensor on some previous models....it's just a holdover.

Jack and Randy got it and mine makes three. When you pulled the drain plug was there not a magnet attached?

 

Walmart normally carries Rotella T 15W-40 which is a very good choice for motorcycles. You can pay more for "motorcycle" specific oil but you are just paying for advertising or low volume sales. Watch for when 5 gal buckets of Rotella T come on sale. Not just at Walmart but they tend to be very competitive,

That's for an emissions test/tuning rig. There is a port (plugged with a small bolt) in each of the four exhaust pipes. For the emissions rig those plugs are removed and gas sensors of the test machine are screwed in. The machine also has an oil temperature sensor that screws into a blind hole on the drain plug.

 

That screw is to keep the hole for the temp sensor clean. Ignore it.

I guess I bought into the wet Clutch thing... I thought you couldn't use regular oil, because it would mess up your clutch!!

When I first read this I got a little chuckle. I then went back up to the picture. I didn't even realize I had a picture of the plug in the exaust. I believe some good shops will also use this for fine tuning the bike. Wouldn't that be how they check your rich/lean mix when syncing and fine tuning your carbs for optimal performance?

 

I actually looked online to make sure that was the oil drain plug. I had seen it there before just never really thought it was to drain the oil.

Well, you don't want to run standard motor oil in a wet clutch bike. It does booger up the clutches. The detergents and additives in diesel engine oils work well for us though.

It's the additives in the energy conserving oils that can cause a clutch to slip. Those oils should say "Energy Conserving" in the API circle on the container. It seems like it's mostly the 5Wxx oils that have that designation.

That's EXACTLY what those plugs/caps are for, using a CO sniffer to set each mixture for a reading of 5.1. A tad more accurate than using a colortune plug...
