So, I REALLY don't like that oil cooler. It's ugly, and oh so pervasive.

So, I'm thinking of just gettin' rid of it!
Yea, I COULD get a mega-buck aftermarket one that's less obnoxious, BUT WHY?

I mean, none of my other bikes have one.
I know it helps keep the temp.s down, but by how much?
I'm thinkin' it's negligible. A radiator and water cooling would make it run cooler as well, but it ain't got that! (Thank God! )

I'm planning to get one of those cheap oil temp. gauges that fit in the oil fill hole, and see how much of a temp. difference it really makes. I believe there will be SOME help in cooling from the less restrictive air flow hitting the front (exhaust side) of the cylinders, making the loss of the oil cooler balance out. (or CLOSE TO IT)
My concern is, Can I just block off (plug) the oil cooler lines where they enter/exit the motor for the experiment, or is that flow path essential for the oil circulation?

Has anyone discussed this, or tried it before my time (B.C.) ?

This is an interesting topic. I hope someone with some expertise answers your question. If Harleys can live without oil coolers, shouldn't our bikes fare better?

I'm sure the dry sump has something to do with it on the Harleys.

I am thinking it should be fine but then I am thinking, the engineers went to school for a lot of years and burned up a lot of motors before they settled on this one.

Don't know how it would fare in a traffic jamb.

The 865 cc engine internals are stock, but the removal of the oil cooler threw me at first. It’s apparently had no injurious effect: “with richer jetting and new pipes, oil temperatures have not been a problem,” says Hammarhead. “I constructed a custom Spurgin oil cooler for the bike, but while I was waiting for the lines to arrive, my brother encouraged me to throw in a few plugs and light the bike. We ran it with an oil temp gauge and slowly became more confident. For nervous folks (like me) an oil cooler is a no-cost option.”

Well... gotta chime in on this one.
Engineers are a pretty smart bunch of folks and bean counters are bean counters so if the people who designed the engine didn't really think it needed it, it wouldn't be there. X amount of dollars per unit... think about it.

It's your bike so do as you will but mine will be staying right where it is.

I'm almost in full agreement with Chy - Especially down to mine is staying where it is. However, one would have to be inclined to believe the thing, without any forced air induction, is virtually useless at the time heat is most likely to spike - hot ambient temperatures and stopped in heavy traffic. So, my guess is the engineers and accountants followed the instructions of the legal department to devise a way to maintain engine temperatures within a set range for some average of time as dictated by some government agency as an effort to stabilize operating temperatures which inpact emissions characteristics. In short, I'm saying it's there for a reason, but I suspect the reason may well not be the reason we might suspect. Just the same - mine is and will remain where it was hung.

The Sr. Tech at the shop where I bought my bike has a 904 Scram without the oil cooler. He says it does just fine. I've ridden the bike, & have no reason to doubt him. He removed it for weight savings.

I'll do that, and see if I can get a response from Triumph themselves.

All the other (earlier) Triumph parallel twins didn't have them, and arguably, MOST other bikes don't either.
NO DOUBT IT HELPS, but again, to how much of an extent. (and again, the wind flow on the front of the hottest side of the cylinders WOULD be improved).

Yes, the engineers approved it, but sooner or later, they'll probably "approve" water cooling, with a BIG, UGLY, FUGLY radiator too.
As long as I get conformation that the elimination of the oil path will not be a problem, I'll experiment and collect data on the oil temp. change, IF ANY.

Don't you think the elimination of that UGLY, FUGLY, P.O.S. would be a KILLER improvement on looks!??

I hardly notice it's there.. it's not like it's the size of a Rocket 3 radiator. I keep the cooler lines polished anyway, kinda like the way they look.
Ahhh to each their own.. good luck with your mods.

I've got ten thumbs but I was thinking,if nothing else the cooler and pipelines would increse the oil capacity by at least half a litre ,so that in itself would be a good thing ???

Good point. 1/2 litre is about 20% of the total oil volume.

also, the oil is either going to go from the EXTREMELY hot engine internals though a heat sink at room temp or it's going to go from the EXTREMELY hot engine internals back to the EXTREMELY hot engine internals.

I don't know that it's strictly required but i
d bet money it does reduce the oil temp noticeably.

On the old twins we used to put oil coolers on them and the oil tank being seperate from the engine would also bleed off heat. I am leaving mine where it is, I have reached uncomfortable temps in traffic.

So, of the four who have ACTUALLY removed the cooler, (to date, Streetmaster, Hammarhead Ind. [Jack Pine Scrambler], The Tech. Ken knows, and Rod Burner) and run their bikes to more extremes than I probably do, they ALL say there's been NO NEGATIVE EFFECT.

In EVERY post, I've stated that the oil cooler MUST have SOME benefit , just trying to determine HOW MUCH benefit. (as opposed to the benefit of gettin' that damn ugly thing OUT OF THERE!)

Just think how safe, and how much better we'd be If, in addition to the cooler, we ALSO added the extra cooling and volume by adding both the oil in frame and the oil bag . Now THERE'S a thought.

I still haven't verified that the lines can be plugged, without damage from interrupting the oil flow path. (though from reading the articles from those who have done it, it does seem to verify that it doesn't matter)

Once I'm convinced of that, the testing with the oil temp. gauge SHOULD prove (to me, anyway's) WHAT the temp. difference ACTUALLY is.

(Sure wish SOMEONE ELSE would test this ) (then again, I guess those above have)

It would be NICE to see one, and talk to someone who's done this, at Daytona in a couple weeks!

Sounds like you're trying to talk yourself into it. Just do it and let us know how it goes. No one here is going to give you the "go ahead" because nobody knows. I certainly don't and the only way I'd risk it is if I was going to turn one of my bikes into a show only bike. The problem is traffic. If you're going to race, well that means movement. The air cooling over and through Dwight's beloved fins are probably enough to keep the oil from frying and breaking down. But the rest of us live in the real world, with traffic and stoplights. I certainly wouldn't risk it. But hey, knock yourself out. Just don't expect any sympathy if it melts.

"Modern Triumph Bonneville and Thruxton engines are oil cooled as well as air cooled. As such they are fitted at the factory with a supplemental oil radiator of questionable looks.

Streetmaster ran tests to determine the efficiency of the factory oil cooler in comparison to running the oil through the tubing of a replacement sub frame. It was found that the sub frame cooled oil temperatures dropped at least 20 F more than the stock oil cooler. This was due to the large surface area of the tubing and an increase of oil capacity of almost 1 liter. The result is a much cleaner appearance and reduction in complexity.

The unit is a direct replacement and installs in less than 1 hour."

you need an oil cooler. I tried to find the article in American Iron about how Harely is doing a dis-service to their clients by not having one. You coul make one that would be cool with some aluminum or cooper tube if you are creative. You need x amount of turbulent flow to be optimal after that the sky is the limit.

Harley's are a different animal, with the rear cyl. blocked by the front cyl.

I have been looking at coolers on ebay, preferably a polished brass one, but nothing that strikes me to date.

REALLY lookin' to just "can it", but a nice, smaller, BRASS one....

If ya want to give it a go, find a fitting to connect the two oil lines together as a temporary set up. Remove the cooler, wait for a hot day,. as in 80+
Drive down town in Friday rush hour / stop and go traffic and let us know the outcome.

Ways back when I was a yute, I had one of them 650 Yammers that was basically a Triumph copy. I was living in San Diego where it is pretty hot too. It always ran really hot. I installed one of the Lockhart oil coolers, basically just like ours. It made a HUGE difference in engine temps. I would keep the oil cooler on.
The best test would be with bypassing as suggested, and installing an oil temp gauge to check the difference. I bet you will find it to run much cooler with the cooler. Hmmm, I bet that is why they call it a cooler maybe???

That's not the same as just removing the oil cooler as you're proposing. You gonna convert your frame?

No, wouldn't want the oil in frame thing either.

Was just thinking of plugging the holes at the motor, and then it would be just like every other air cooled motorcycle I've ever had, or have now.

I live in Florida, where any winter day can to be 80+, and every summer day is 90+.

I've gone to many Bikeweek and Biketoberfest events in Daytona over the last couple decades, where "Traffic Jamb" is SUCH an understatement!, and temps are 90+, the asphalt probably 140, and never had a air cooled bike with a oil cooler.
Never seized one, never blew one up. But maybe the Triumph motors can't Handel it like the Jap bikes we've all had since what, 1950's?

But I agree, the ONLY way to tell is to "Git R done"

Are those little temp. gauges that plug into the oil filler hole good? Do they have a sensor that dips into the oil itself?

I don't think the "Jack Pine" bike, or the one owned by Ken's dealer, had ANY oil mod done other then just plugging the line holes, and removing the cooler.

Ken, Does your head tech. at your dealer EVER ride in NORMAL traffic?

Would SURE like more input from his experiences, since he MAY be the only one mentioned yet who has actualy done it, rode it under normal conditions, and would be a reliable source.

Get some tubing and wrap the down tubes of the frame. Or relocate it to where the air box goes.

I'm gonna do some thing with the oil cooler on the 02 I'm working on but I'm not sure what yet. I'm trying to make a 60cal. round into a rear brake reservoir right now. oil cooler next.

You should have some kind of oil cooler. The older twins had a block of solid metal between the cylinders to help carry heat around to the fins and the dry sump oil system helped cool the oil. The new twins have a hollow spot between the cylinders where the cam chain runs. To make up for the lack of heat sinking metal there, they cool some of the oil and pour it down the cam chain slot. The long term effect of taking away this flow of cooled oil is that the cylinders will heat unevenly and change shape. This will cause uneven wear on the cylinders, pistons and rings which will shorten engine life. This might not matter so much on competition bikes because they usually get rebuilt every season.

Arg, i don't think i would remove it, i really never seen it as being that big an eye sore to be honest with you. At least its in line with the frame not like some that are way out front or inside the frame.
