New, New Oil Cooler Adapter!

[terry]

Ok guys I just recieved my oil cooler adapter from terry and got it on the bike. Looks awsome. Can't beat the price for it. just add the cooler, filler up and go. great job on the machining! SWEET!!

Thanks Terry!

With nice words like that mate, you're always welcome, enjoy! :twisted:

oil cooler

I have seen a couple of oil coolers fitted, one in particular had the return line into the oil filler. Would there be any benefit to this.. I assume the idea is the cooler oil on to the clutch basket is a benefit.

Mate do you have a fairing for your 1000St?

G'Day Simon,

Well this question takes me back to when I first started thinking about coolers on my GS, I thought that I could use the oil pressure take off under the cylinder block to feed the oil to the cooler, then dump it back in the filler like you described, but sadly, it was a "no-go", because the end result would be starving the whole top end of your engine of oil.

I too have seen what appears to be an oil return line that feeds into the filler, but in fact it is a crankcase breather with a little filter on the other end.

I've looked at all the popular oil cooler adapters from the 1970's and 1980's (in fact, mine is pretty much a rip-off of the now obsolete Earls ED40) and they all took off from, and returned to, the oil pressure switch plate behind the cylinder block just below the cam chain tensioner.

I do have the original fairing for my GS1000ST, but not on the bike, it's hanging up in my garage with a new screen that I bought for it all those years ago.

I need to repaint the fairing, it's had a light scrape down one side, only a scratch really but the paint is really bad, the white has "yellowed", and doesn't match the rest of the paint at all. It's the original fairing for the bike (I'm only the second owner from new) No biggie though, I don't intend putting it back on the bike anyway.

Hey Terry, I understand the thinking, I am sure I saw the oil cooler return
via the oil filler on Tony Armstrongs Turbocharged 1000s.
Good luck with the fairing painting, I did have some stuff in the painters and they have made a mess of it.. Now its going to cost me another 1500 to get it fixed.. but I have 40 metres of the white/orange and black pin striping..

G'Day Simon, I suppose it's possible that you could run a "splitter" hose directing the cooled oil to the clutch as well as the top end, but I'd be wary of not feeding sufficient oil to that area as a priority.

Interesting concept, but I wouldn't be keen to gamble on possibly trashing an engine as an experiment........

I wouldn't mind a couple of metres of that striping tape though, I have plans to paint a spare tank and ancillaries that I've got hanging in the garage for my second bike, let me know if we can do a deal? Cheers, Terry. :twisted:

Terry if you email your address to me simon.lambert@volvo.com
I will roll off a couple of metres and post it to you for nix..

Is it possible that this is a seperate oil return from the turbo?
On a GS you may want to use a seperate pump to generate enough oil pressure for the turbo, due to the low pressure in a GS engine.

Oil cooler

Ok so now I found someone who builds that adapters and a cost. Now, How well do they work? I only ask as I got into a discussion with a chap here about them and he says that the engines did well without them. So, educate me folks.

Yes, the engines can go without an oil cooler.

But...

have a look at later air cooled motors (Bandit, GSX14 etc) they have large oil coolers. If you want the engine to last and make power consistently, an oil cooler will keep it going longer. particulalryl if you do any modifications as the extra heat produced is very noticeable.

I had to rebuilt my standard 78 Gs1000 after 70,000kms, no oil cooler, full fairing a lot of the time. Since the rebuilt, far more power, larger oil cooler most of the time, after another 80,000kms, compression is as good as when I rebuilt it.

Make up you own mind. If you don't ride much or are not going to keep the bike for long (I think in decades) an oil cooler may not suit you.

There are many members of this forum more technically qualified to speak on this subject than I am. What knowledge I have comes from having an oil cooler on my 850 for 95,000 miles. I installed it with 5,000 miles on the bike and had it taken off when I had a complete rebuild of the engine at 100,000 miles. The bike was still running good; I just wanted to make it new for the next 100,000.

So I can say from experience that an oil cooler at least doesn't harm your engine. And given that our engines are air cooled my reasoning is that anything that reduces or dissipates heat is pobably a good thing. The only words I have read contrary suggest that in colder weather an oil cooler may delay or prevent the oil from reaching optimum operating temprature. Since I live in Florida I have not given that as much thought as someone further north might. I suppose one could cover the cooler on cold days if that were a problem. I would suggest running a multi-grade oil (10W40 or 15W50) with or without a cooler. I also ran synthetic oil when I had the cooler.

It is coming up on 10,000 miles since the rebuild. Now that it is fully broken in I will remount the cooler and go back to synthetic oil. My previous experience and my gut feeling is that they lengthen the performance life of the engine. Even if they made no difference for 90% of the riding I do, it is worth it to me for that little extra peace of mind when I do encounter extreme riding conditions or when I'm not able to do maintenance right on time.

I am putting one on my bike this year now that I am overhauling the engine. I'll wait for a few thousand miles but then I am putting it on. I am also thinking about fitting the front of the engine with the cooling fan assembly from other liquid cooled bikes without the shrouding so that I can sit longer in traffic without worries. I go on rides with the cruisers and those guys can sit on a hot summer day for any length of time and not over heat. I did this last year going to the Carlisle Corvette show and we got stuck in traffic getting into it for over 1.5 hours. I was shutting off the engine and everything but then I could not push fast enough to move ahead when it would move so people would beep at me. It got so hot that it wouldn't run right and after that it started smoking for the first time since I owned it. I vowed to never let this happen again. So I am going to see about making up a mount that will let me attach the cooling fan/s from a liquid cooled bike so that I can turn them on when sitting in long waiting traffic and at least have some air flow over my heads and through the oil cooler. I am planning on making it so that I can put in on and take it off easily so that I will only have it on for rides where I think I will need it.

I'll start a topic on it in here when I actually get around to it.

That is a great idea, I too have spent countless days in the summer months when sitting in traffic the heat from the bike was too much.

An cooling fan would be great. Keep me informed

The GSX14 has a thermo fan fitted standard, and it has a HUGE oil cooler. And it only has as much power as my bike.....

A thermostat can be fitted to oil coolers, such as the Permacool ones. Temperature control leads to better tolerance control, and more power over a longer time. The bike can however last a long time standard, but once you improve them the heat output increases a lot.

No problem mate, sorry it took so long to reply, I was just looking at these old posts when I saw your post. Hows that bike going now? Must be warming up over on your side of the "pond"? Cheers, terry.

Hi Terry
Wow that oil cooler adapter really looks the business.
Have you ever thought about making a top end oiler fitting? like the one in this picture but for a GSX1100EF/GS1150

I would definitely be interested, I can imagine others like Gerry and Dink would be too
