Oil cooler Install

[Anonymous]

The diagram shows the dual route to the filter - either through the colloer or what they call the bypass. It doesn't show the oil cover 'cup' that Sexton7z is refering too.

Look at the last picture i kz's post. http://medlem.spray.se/ocorsagsi/Oil5GS1150.jpg
Letter B is the cup I referred to. Doesn't show up terribly well but it's there. It is not there on the 1100 cover.

Give me about an hour. I'm going to pull mine and take a picture side by side with the 1100 cover.

OK, here we go.
The 1150 is on the right and the "cup" is in the bottom right corner. Cup really is bad description. It basically blocks the the incoming passage. I originally thought the notch was about 3/8" wide but it's only about 1/8 wide and an 1/8 deep. I figure almost all the oil will pass through the cooler now that I've look at it again.



Here's a picture of the cup from another angle.

Nice pic - shows it clearly.

I just looked at some 1150's on this website and it looks as if all of them have coolers. Ok, the question that I have now is "Does the 1150 come stock with an oil cooler?"

From looking at the cover for the 1150, I think it would need one to get the quantity of oil to the filter necessary for the engine to live. Without a cooler, all of the oil must pass through the tiny orifice that is machined into the cover -> not good.

If the above it true, then:

1) This would mean that severe engine damage could result by removing the oil cooler -> plugging the external filter passages.

2) Could it be that Suxuki discovered that too much oil was bypassing the cooler (when an external cooler was installed) in the 1100 and fixed it in the 1150.

3) Which implies that I should get the 1150 cover if I am considering an external cooler.

All in all - thank you very mcuh for shedding some light on this for me. Very well done.

I think all the 1150s had coolers.

1. Oh yes, I do think so. But I guess you could put the 1100 cover on 1150 with the cooler removed to allow unrestricted flow to the filter?

2. Perhaps? The 1100 block certainly was cast with a cooler in mind. Don't why it didn't ship with one.

3. I would (and am going to) get the 1150 cover if installing a cooler on the 1100.
I've got an 1150 cooler for my 1100 already. The bike is currently scattered all over my garage but I hope to have it back on two wheels by riding season.

1) The covers seem pretty interchangable as long as you use an oil cooler on the 1150.

2) My guess is that the engineers knew they wanted to fit (or would have to fit) on oil cooler eventually. Due to various release time limitations they designed in the fittings and left the rest until later. By the time the 1150 came out they had the oil cooler and bypass flow porting tested and ready to go.

Maybe - maybe not - good story though.

In any event - unless someone throws a monkey wrench into this thought process - the oil cooler configuration issue is resolved for me.

If you use an oil cooler -> use the 1150 cover.

Oil cooler Install

Yes I think everything is a lot clearer than it was for me in the beginning. I'd like to thank everyone for replying on this matter. Thanks Guys Now all I have to do is find an 1150 oil filter cover and I'll be in business.

In an earlier thread http://www.thegsresources.com/_forum...pic.php?t=3321 I asked about removing the oilcooler on my 1150, but I never understood, what the "By-pass" on the http://medlem.spray.se/ocorsagsi/Oil1GS1150.jpg was, so I cancelled the removing of the cooler.

If I understand correct now, I can remove the cooler if I also change the Oilfilter "cup" to a cup from an 1100 ?

The "By-pass" on the http://medlem.spray.se/ocorsagsi/Oil1GS1150.jpg is there letter B is on http://medlem.spray.se/ocorsagsi/Oil5GS1150.jpg ?

Have I now understod correct, and can I safely remove the cooler??

Yes, if you use the cover from an 1100. Do not remove the oil cooler from an 1150 motor without the 1100 cover. There is a restrictor in the 1150 cover which forces more oil to the cooler - essentially 90+% of it. The only oil you would get would be the little bit that goes through the bypass.

The letter "B" on your diagram is the bypass - teeny little guy. Perhaps it's there to provide "just enuff" oil when someone inadvertantly removes the cooler and plugs the holes.

Never thought to ask - but if you want an 1100 cover - I would trade you mine for the 1150 you have straight up. Postage would be your only investment.

I live in Colorado and the summers here get hot. I'm going to use a cooler.

Thanks for your reply and offer,

But I'm an "original" freak and have keeped all stock parts to the bike, which from the beginning was an GSX 1100 EF.

I like the possibilty to build back into original shape, when I repainted it I bought all parts that should be painted from a junk yard and still have the original.

Oil Cooler,revisited

Gentlemen,
Thank you , one and all for your solution of my oil cooler installation by the dealer. I had them mount a GS1150 oil cooler but it stayed cool to the touch. I had asked about it last year in this forum but it took awhile before the solution was determined. I ordered an 1150 oil filter cover and now everything works fine....as fine as it can be with three foot of snow outside.
Now I'm looking for answers to installing a headlamp relay and keeping the "headlight out" lamp if for no other reason than to indicate the relay coil situation.

I don't mean to divert the conversation but what are the benefits of installing an oil cooler. I mean real world benefits. :roll: Also, could a 850G benefit from an aftermarket cooler. Yes I know I don't know anything but humor me

As I understand, not only will the oil be able to cool the engine better but it will also retain it's viscosity. The cooling is essential for the oil cooled electrical charging system and will provide fewer breakdowns. It helps the transmission work better,too.

i have a few questions about a oil cooler, its a 78 gs 400...if i installed an oil cooler would it be better to direct all the oil through it or a little i think alot but i want ur opinion , and also if i mounted on fans to the oil cooler would it be better to have them turn on and off with a temp switch or constant running, also whats the point of a oil thermostate if u dont have one isnt it better because ur not giving the oil a fast chance to get hot................oh and u should see the way im installing mine

[Anonymous]

theres a problem i have just come up with since my bike has roller bearings doesnt this mean it has a lower pressure pump.....can i still use an oil cooler...i was thinking of a way to use the oil cover with the filter inside but still direct all of the oil out of the nipple on the bottom and go through the cooler but i dont know if i can do it now....one time i was revving the engine and the side clutch cover was missing and the clutch push pin flew out and sprayed oil everywhere....not exactly that low pressure is it
