Adding an oil cooler to my 1100

[somekindarod]

A guy I was doing some work for asked me, How much would you give me for those two 1100 yamahas? I said, I dont want those f-ing things. He said howbout if I gave them to you. I said buddy lets load them up.
A friend and I got one going right away, a 1980. I put all the best parts on it. tranfered the title and sold it for 1100 bucks. The 79, I sandblasted the tank,painted everything forest green, redid the seat, blasted the pipes and painted them black with high temp paint and put 15 dollar tractor mufflers on. Removed the ft fender and airbox. Then put drag bars on it. I got little kids giving me the thumbs up all the time. I love this bike.
The 79 had around 84000 miles on it when I got it. People,,,,I beat the crap outa this bike. Scary for sure,,, had it up to 130 with more left in it,,, burnt off two tires doing burnouts. Replaced the clutch and brakes. But I cant brake this thing.I have over a hun thou on it now. I put on about 3500 a year. I think I may have stretched the drive shaft a little tho.
I think the guy I got this bike from really took good care of his stuff
The question I have is the 1980 had an oil cooler on it, I took it off plugged the holes in the engine and saved it. Now I want to reinstall it on the 79 but dont remember how to hook it up. I`m hoping someone has one on there bike and can tell me how to do it
I just picked up another 1980 that looks like its been rolled,flipped and slid down the road at 120 mph. Hardly any good parts on it but the engine has 34000 miles on it and runs great. Maybe I can brake this one!
Help me, I can help you. Seeyalater, Dan

The stock oil cooler on the 81 has an adapter between the engine and the filter cup. Truth is, you don't need an oil cooler.

The holes you plugged were in the adapter plate that mounts between the oil filter housing and the engine. Can't mount the cooler without it as there is nothing to connect it to.

The adapter consists of the plate and a special hollow bolt that mounts the adapter plate, and still allows the oil filter housing bolt to screw in.

Make double dog sure that you remove those plugs, and either reinstall the cooler, or find a way to make a bypass hose between the two ports on the oil filter adapter. Oil must flow through these ports. or it will be deadheaded at the plug, and would cause major damage.

John,

He may not be as DeadHeaded as you think. The Cooler plates I've seen have a built in bypass valve for such a condition as kinked/clogged hoses, so it may still flow from plate down to filter cup and back to engine!? However, like Skids said, he probably doesn't really need it up there where he is!

Oh, I thought he had no adapter on the bike he is working with presently.

I dont remember there being an adapter plate on the original bike the cooler was on. And I dont have one now. Are these plates hard to get?

I have seen non OEM oil coolers that tapped into the oil pipe on top of the engine (but I don't know where the other tap went to).

That sounds more like it.
I may not need the cooler but I have it so I thought I`d put it on,,,right next to the nitros bottle!
I`d like to port the head, bore the cyls as big as I can, fork stabilizers and a fog box for the nitros. I want to lower it as much as I can.

I first came to this site about 6 years ago and seen Jeremy Kayes bike, 79 xs 1100 must be a special. The standard tank takes a real beating by the drag bars, specialy when the old lady drops it in back of the pickup. When I redo the tank I`m going to have to extend the fork stops somehow. Any ways I liked this guys bike so thats the look I went for. The forest green (rustolium) looks good. You should have seen me at the gass station in my camo with my shot gun strapped across the frount going duck hunting, I got a few looks.

Skids,

They probably just tapped into both ends of that pipe, the lower tapped section going INTO the cooler, and then the line out of the cooler going into the Upper tube and finally to the topend of the bike, cams, etc.!

But I've heard it's not necessarily recommended for fear of loss of flow to top end and oil starvation damaging cams!?

If you're(Some-Rod) going to bore it and NO2 it then you possibly could use the extra cooling! But might be better getting the PLATE with the proper fittings to match the cooler vs. just C-hose clamps!

I like having an oil cooler because I can "feel" The temp of the oil at the brass fittings. Eventually I want to put a temp gauge on it.
