Oil cooler Install
When you install an oil cooler on an 1100e, where is the proper place to run your lines from? I've seen some lines that run off the oil journals of both sides of the oil filter plate. Then I've seen some oil coolers with the oil filter plate drilled fittings installed directly to the cover. Then I've seen some folks that run the oil cooler through the fitting where your pressure sending unit is. So what is the best route to go here Cause I'm kinda confused here.Tags: None

I'm going to run mine through the oil journals on either side of the oil filter.
Need to get a oil filter cover for an 1150 first though. Apparently there is minor difference between the 1100 and 1150 cover that routes the oil through the cooler (cooler I'm installing is from an 1150).
If you notice there are two saddles directly above the oil journals that nicely take the oil filter lines. Think that was their intent originally.

Does anybody know what the differences in these two covers? Does anyone have a couple of these covers?

I have both an 1100 E & a 1150 E out in my garage. I've looked at them a couple of times, to see if I could see any difference. They look exactly the same, while mounted on the bikes. I would also like to know the difference. This spring, I will be sure to change the oil in both bikes at the same time, have both covers off at the same time so I can take a closer look.

But yes, from the outside they are identical.

I posted earlier on the oil passages on my GS1100E after I tore down the motor and split the cases. This was a visual inspection.
Ok, I just finished looking at some more of those oil passages. In particular, the oil passages connected to the two threaded connections on either side of the oil filter, presumably meant to be used for an external oil cooler. It looks as if they do allow oil from the pump to pass through the cooler if an external one is used. They do not force all of the oil through the cooler however. The configuration suggests that only a percentage of the oil will actually pass through the cooler.
With an external cooler present the oil flows from the oil pump to a split in the passage that allows oil to flow either to the filter cavity (larger passage) or alternatively to the external cooler (smaller passage). The oil passes through the cooler and enters the block through the second coupling where it is directly routed into the filer cavity. So, one path is from the pump to the filter through a large oil passage (less resistance). While the other path is from the pump to external coupling (smaller passage = more resistance), then through the cooler to the other fitting (more resistance), and finally to the filter cavity (smaller passage = still more resistance).
How much oil is going to pass through the cooler? I won't commit to that right now, I'm just trying to understand the system so that any modifications work as expect and I'm not throwing money away on gadgets that don't work.
If one was ambitious enough this portion of the oiling system could be calculated if all of the passages were measured for both diameter and length and the fluid resistances understood for the right angle changes in direction for said passages. I think it would be safe to say that < 50% of the oil from the pump actually passes throught the filter.

I just notice that I made a mistake in the previous post. I said:
I think it would be safe to say that < 50% of the oil from the pump actually passes throught the filter.
I think it would be safe to say that < 50% of the oil from the pump actually passes throught the COOLER. (All of the oil passes through the FILTER).

On that last sentence
"I think it would be safe to say that < 50% of the oil from the pump actually passes throught the filter."
Did you mean say pass through the "cooler"?
From the way it looks to me, my 1100 engine is currently tore down, looks like only a portion of the oil will passs through the cooler than return to the filter cavity and through the filter.
Thats where the "cup" (really bad description I know) on the 1150 cover causes more to flow through the cooler than if the 1100 cover was used. The "cup" is basically a raised cylinderical ridge same diameter as the incoming oil gallery that appears would actually block the incoming oil except it has a notch approx. 3/8" wide in it that allows the oil to go ahead and flow into the oil filter cavity. The other portion of the oil goes through the "cutoff" passage, about 3" back in the gallery, that leads to the cooler than back in through the other side.
Baring my mutilation of the English language, does that pretty sound like what you see?

You got me before I could repost!
I don't know what the old cover looks like on the 1150 - but your assesment is correct for the 1100. The filter cover has a 'bubble' or 'cup' - an area on it that lets the oil pass into the filter cavity. Without this - if the filter cover were machined flat - then the only way to get oil to the filter cavity would be to use the external passages setup for a cooler.
I imagine that Suzuki put some thought into this and determined that all of the oil does not need to pass through a cooler. In a cooler climate, this would not allow the oil to reach its proper operating temperature.
To properly deal with temperature extreemes the ideal solution would be some kind of thermal bypass switch. Then again, there are quite a few here that don't use a cooler at all and their motors have lived long and happy lives.
To sum it up - I don't have any answers. Right now I'll probably add a cooler when I assemble the bike and use the two taps on either side of the cover. I'll trust the Suzuki engineers.

Don't think it could cause a problem not using the 1150 cover when installing a cooler on the 1100 but I don't think it would get much flow without using it.
Wish I had a picture. (thousand words and all that).
Any of you 1150 owners out there changing your oil soon?

So does anyone out there have a picture of an 1150 cover? I just wonder if you could maybe build this "cup" up on a 1100 cover. I've got a buddy that welds aluminum. Does the cup come up flush with the edge around the outside of the cover?

Scanned this pics. when the tpoic was discussed earlier.

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.
I'm trying to visualize this. Could it be that the Suzuki engineers where trying to reduce the flow of oil through the bypass if a cooler was used by adding a small restriction?

I have the complete manual (and the bike), do you want me too scan anything more?
If yes, I can do that.

oil cooler
use the 1150 cover plate, there is a difference between the 1100&1150. ive ran external oil cooler for years on my 82 1100ez.it works fine and yes it gets hot, it flows plenty of oil..
