Oil cooler from GS1150E on a GS1100E.

[cdnoel]

Hi all.

Just getting around to working on my 80GS1100E that I previously put and 1150 cooler on. It was recomended to me by the guy who sold the cooler to me and a few other GSR members to plug the hole under my oil filter cover in order to make my oil cooler work. I have the oil drained and wanted to ask one more time before doing so WHY? The hole in question looks to be the only way for the oil to get into the filter housing. I can't see any way for the filter to continue working if I plug this hole. I want my cooler to work but I can't for the life of me see why pluging this hole would help or how the filter would function afterwards. Am I mising something? Please save the smarty pants "your going to blow up your engine" cracks for some one else. Thanks, Chris.

I think you need to fit an 1150 oil filter cover to make it work. There have been threads in the past on this subject with pictures of the difference between the two covers.

Plugging the hole and an 1150 cover is the same thing.
Just do it. You'll be ok.
I've never had oil starvation using the plug I gave you.

Ok you dont have blind trust . Study the manual for the oil schematic and visual. The oil for the oil cooler has to be diverted from the pump away from the filter and then to the cooler. After traveling to the cooler it is returned to the filter.

EDIT: These comments refer to using Banjo ports with the stock covers (either 1100E with a plug or 1150 with no plug)

When you block the passage on the right side of the motor, you force oil out the banjo so it can go to the cooler. You block by either sticking something in that port of using a cover that blocks that port.

After coming back from the cooler, the banjo on the left side allows oil back to the oil filter.
.

Simple this is how Suzuki designed the oil ports.:lol:

EDITED:
Look in the manual there is a schematic of the oil. Oil without cooler goes:

a.) Sump
b.) Pickup
c.) Pump
d.) Filter (there is also a bypass if the filter gets plugged ; the pressure will overcome the spring)
e.) to the sensor plate under the carbs.

Ignore the 8V stuff for coolers, the plumbing at the front of the 1100E avoids their problem of capturing all the oil and sending it to the cooler and then returning to the engine.

If you are going to use a custom machined cover, then you are not using the banjo bolts and the banjo ports on left and right side of the cover remain plugged.

On the right (engine) side of the cover, you need to trap all of the flow from the right hand port under the cover with an AN fitting ( this is the entire flow coming from the pump).

All that flow goes to a cooler. Bring the return back to yet another hole/AN fitting on the left hand side of the cover; the oil now will pass through the filter and spread to the rest of the engine.

The return could also come back to the left hand banjo port but usually people do teh custom cover to avoid the expense of the metric banjo fittings.

Ok.

Ok.

My gaskets are in for the exhaust and oil pan so I'll have this figured out this weekend. Thanks again for the info. I'll work on the blind trust thing.

1150 Filter covers are still available from Suzuki.

 

[rapidray]

If it were ME, I would just use an 1150 cover & be done with it. No confusion that way. Ray.

So, ANY 1150 with an oil cooler has the proper filter cover? BB cost $68
OP, look here for a better look:

Did some measuring last time I had the filter cover off (1150) in case you want to try modifying yours.

Is that a circular hole or oblong?
I was planning on having mine welded and then drill an appropriate size hole. Cheaper than a new cover, and they seem pretty scarce used.

IIRC it is 1/2 of a circle

Don't know if there are any on the bay currently, but these (1150 covers) appear there quite often, actually....usually at 1/4 the $68 quoted for the new one. Remember to switch back to the stock cover, if you ever take the cooler off (or remove the internal plug, if you go that route) to avoid a toasty engine, though.

EDIT: Member Pousseux (Mike) in Quebec has a massive inventory of 1150 bikes & parts...probably worth sending him a PM, or posting in the Parts Wanted section.

Plugage on stock cover

Plugage on stock cover

I just want to clarify a couple of statements that are in this thread. I toasted a set of cams and rockers on a 1327 motor and was schooled by Ray to run a cooler and top end oiler for safety. I have the oiler coming from a member here and have seen 1150 coolers on Ebay fairly cheap.So it sound like I should buy a 1150 cooler, buy a plug from Chef, buy some hose and clamps and I am almost there. Are there fittings by the filter cover or do I have to drill and fit external connections? Any comments would be helpfull...

The holes on mine are pre tapped, you just need the union bolts (back ordered) or whatever to thread in there, then an 1150 cover or plug for the oil passage.
I plan on having my stock cover welded then drilling a small hole for restriction.

Look for an entire 1150 assembly (cooler, hoses, banjo bolts) and an oil filter cover from that bike too (or a plug) and use the two factory outlet/inlets on either side of the oil filter cover. You might need to make a simple bracket, or modify the hole spacing on the 1150 cooler bracket to bolt it to your 1100.
Frankly I'm surprised to went to that big bore and the rest of the mods without using a cooler. Even with the 1150 cooler, a 1260 I rode (not mine) put out significant amounts of heat.
Post here in the Parts Wanted section, and maybe someone will have the 1150 parts for sale.

On a cold day in Santa Barbara (50 degrees), my 1166 will climb in temp to near 300 going 30-40 mph climbing to Camino Cielo. I did not have much of any concern on a recent trip to Mt Shasta and Oregon (2500 miles) last summer. But I would not try and ride without a decent cooler.

This bike was built in '86 and was owned by a friend... I rode it for one season. Then the meltdown commenced. I found a 1150 cooled on another forum with hoses but no bolts... I wil continue to search... Thanks for the reply

Ray clued me in on the necessity of a cooler. I have all the paperwork from the builder of this bike and one of the notes was " A oil cooler is required for summer riding". The dyno sheet showed 181 hp at 9800 rpm so yes if was a hot runner...I hope to put it back together in the next few months. I have been collecting parts for over a year, and am getting close... Thanks for the reply.

Got the plug in.

Got the plug in.

I got the plug instaled and found the passage ways I was looking for to confirm that my oil would still keep flowing. Since I have my oil pan removed I discovered that the two oval shaped depresions in the front of the cover are the passage ways I was looking for. Once the hole is pluged on the right side of the cover the oil is send through the right depresion in the oil pan. Next it goes through the cooler and back into the left deprsion of the oil pan. After that it feeds into the oil filter.

Knowing this I would suggest that if you ever instal a cooler and use a plug in the oil filter cover make sure you do your own oil changes. I wouldn't be surprized if some mechanic would throw away the plug. Also if you fab up an oil pan gasket for yourself make sure you keep the oval shaped holes at the front. they are critical for any 1100 or 1150 with a cooler to keep the oil flowing through the filter.
