Yes I would tend to believe that your gauge is inaccurate or you are running on the lean side. Been riding these old Suzuki's in New England for over 30 years and have never had one run that hot [ Unless of coarse you count the time I filled my 83 750E with 112 octane fuel] but on pump gas never much over 250 0n a hot day. For the most part barley move the needle

A think dunking the sending unit in some boiling water will tell the story. If the gauge reads close to 200 then its not the sending unit or the guage. If its way over then I would get a new sending unit and redo the hot water test.

Bring your bike south and get some riding in!

You are so right, Scout. I definitely have got to get out of the "Big Apple."

I was actually thinking of moving farther north in NY State when my commitment here is over, which looks to be months if not weeks now...cancer (like rust) never sleeps...a little bungalow on the Erie Canal perhaps...isolated...QUIET...I'll feed the feral cats and ride my bike on the desolate roads. I don't think that's too much to ask.

Maybe fix up an old boat, take my clients fishing. You remember the name of the town? Zihuatanejo.

Whoops...wrong movie. But you get the idea...a place with no memory.

Thanks for listening.

Don't know your situation but about a year ago I moved from the north to the southern states. I'd spent several years working in Alaska, Colorado, N & S Dakota and the pacific northwest. Let me tell you sir, the riding is MUCH nicer when your not freezing to death. Not a fan of Florida specifically but I also spend about a 1/3 of my time in Georgia and it's a lot warmer here than Fargo is right now. I have no kids and not married so it was easier to make a move, if your not held to your area I suggest a move south.

My 1000S will hit 300F easily while running on the highway at 80mph at 85F. The gauge is accurate too (verified by dunking the sending unit in boiling water). This bike is stone stock including jetting, airbox, and exhaust, and runs flawlessly.

Suzuki added oil coolers on the GS bikes starting in 1983 for the 550 & 750, and 1983.5 for the 1150. Just because the early bikes didn't have oil coolers that doesn't mean they hold no value.

"South" is not a bad idea, but do yourself a favor and stop before you get to Flori-duh.

I had the pleasure of meeting a few members while I was down there a few years ago, but the roads are downright BORING.

Any motor oil that gets over 240 degrees Fahrenheit is bad news. Even some synthetic oils start to break down at about 250. Suzuki originally planned on running oil
coolers on all of their models (look it up) but did not to save manufacturing costs and to be closer to Kawasaki and Honda in pricing.
Did anyone besides Grimly and myself read what he/she(?) posted in the 19 banned oils thread???? Why do you think that most oil temp gauges have a red mark at 240 and above???

Here is the link for those that did not READ it: http://speedtalk.com/forum/viewtopic.php?f=1&t=32279

I used to wonder what temp my XJR ran at, so I bought and fitted one of those oil temp gauges where it replaces the oil filler cap, just screws straight in, I don't know the location of the sender unit in a GS1000 i.e. where it picks up the temp reading, mine cost around ?26 a completely different bike I know but but could it be an option. This kind of thing

[GSX1000E]

Even at 120C that is roughly 248F at the TOO HOT mark.
Notice that the normal running range is not over 240... http://www.summitracing.com/parts/sww-214266/overview/
And on this one, 250 is pegged... http://www.amazon.com/Auto-Meter-43..._4?s=automotive&ie=UTF8&qid=1418069825&sr=1-4

If you gauge is working correctly, and it normally goes over 250F, it should be changed very often.

They certainly made it easy enough to install one, and I'm thankful for that.

seeing oil temps in the summer go above 240 is why i bought a sh775 regulator. help drop the temps some

It's on my winter list. My mechanic has the final say.

 

[Nessism]

A series R/R does not appreciably reduce oil temperature. It may reduce stator temperature, but GS bikes don't have a lot of oil flowing up into the stator area so the stators effect on engine temp overall is minimal.

As an experiment I did a back to back test using the same bike, same route, same day, two different R/R's (one series), and there was no measurable difference in oil temp.

?? Could you please explain exactly how you think this is going to lower engine oil temp?

this is where i first saw folks talking about the series regulator keeping things cooler.

http://www.thegsresources.com/_forum/showthread.php?191795-GS-Stator&p=2012092#post2012092

this was the other location.... which Ed also poo pooed. Neither did a controlled environment scientific test like a dyno cell and controlled repeatable engine loading and controlled external temperature. Im going with the test that says it was a little cooler cause it doesnt hurt.

if the stator gets hot enough to burn itself down with a shunt regulator and doesnt burn itself down with a series, its not getting as hot.

it may be negligible for overall oil temp to some but if the stator is cooking even some of the oil that comes in contact with it, that oil has degraded and is being mixed back into the rest of the oil.

either way its not a bad thing to run.

no need to get so excited when no one controlled the test perfectly.

How about a test where someone (me) ran their bike on the freeway, same day, same speed, same distance, two different R/R's, and measured oil temperature? Out and back test with two different R/R's - a SH-775 and a FH-012.

Believe what you want, but it's a suckers bet to think an R/R will reduce oil temperature. Doubly so after someone (me) did a controlled test.

so are you saying that chef1366's results are BS?

cause you both cant be right... or can you..... lol

yeah i still see arguing.

and i already know that the max stator dump is going to be in the 200w range vs the measured output being in the 75000 watt range for an average 1100. with gas engines being in the 25% efficiency range the actual output of the combustion process could be 4x that with much of it being wasted heat out the tailpipe and out the engine fins to the air and some to the oil. so more than likely no one measured the total heat loss via the air going over the engine and the heat out the exhaust to see how much is being shed into the oil. or out an oil cooler.

a better test would be to start with a completely cold bike on a dyno with a constant electric fan and constant load and measured with a datalogger temp vs time. and not with a 30+ year old gauge with little graduations. and stock pos r/r vs sh775.

your test could have been skewed by a headwind or tailwind on the highway. or traffic messing with air currents.

that said its fair to say that chef1366's could have been as well.

you both ran routes that you have observed conditions in the past and one observed conditions that changed and one did not.

now i will admit that a ~200w stator drastically affecting a 75,000-300,000w (or somewhere around there) combustion process seems like an unlikely outcome but there seem to be too many variables in both tests now that i look at the whole scenario.

i still like the sh775. lol

this has little to do with cardboard lol.

Too bad this thread has devolved into a Cluster Fk.

Neither of my GS1100E's have ever exceeded 240F. Never. Owned em both since new. Both stock......except for 2 "upgrades"....I run 115 Main jets (112.5 is stock) and Compufire RR in both. Have checked temp sender operation. Working properly. Even in 100F ambient temps running 5 to 7K RPM, indicated temps never exceed the 210 mark by more than a needle width. Gotta keep up with the Triumph Rocket III and an Aprilia Shiver (sort of) that other family members ride.......

My observation is this.....in 35K miles on one and just over 100K on the other, oil quantity is a factor...and that makes sense, doesn't it? From full line to min line, oil volume difference is over a pint. Running Rotella T or Brad Penn, each machine uses that pint in 1,500 miles. Oil temp does run from below the 210 by a needle width to a needle width and a bit when oil "low." Top it off, oil temp lower.

I am curious, really, why so many of the GS1100's here run so much warmer.

Back to regular programming.

i have the tendency to derail threads all over the internet..... oh look, a squirrel!

mine has hit around 260 or so on the factory gauge (hard to tell with no graduations from 210-320) when it was 90 out running rotella t 15-40 on a straight flat road in 5th at 60mph. stock r/r.

i dont want it that hot. ill check the mix with my wideband to see if its a little lean in the spring.
