Engine temperature dilemma

[Tsiklonaut]

Rided my new 1100 in 2C cold and the temperature rises to 5 bars normal w/o radiator blinding and reaches it relatively quickly - with 10 minutes ride maybe on freeway speed 90-120kph.

My older 1100 never did this, barely 2 bars if no radiator blinding in conditions like this.

Both bikes are 1998 (the new one march '98, older one january '98), exacly the same - with CAT, Lambda. The only difference is the new one has the black engine and two months newer release model (any model modifications between them maybe?).

So why the hell the new bike runs on normal temperature with this cold weather - thermostat fitted, poor oil circulation?

1100GSes have no thermostat, right?

Well it's very nice to have running on normal 5-bar temperature on this cold weather (had serious problems getting to it with my previous GS, especially on freeway speeds, i used various "bliding" methods to get 3-4 bars out), but what happends if the bike hits +35C weather

but what happends if the bike hits +35C weather

Barbeque and beers

and you're asking people who live in the UK??

Be very careful - you'll ride through the end of your greenhouse.

I guess i asked the question a bit wrong then . Well we do have +35C on the summer heat waves here, while we have -35C winters.

So my concern is that maybe the engine starts to run too hot and overheat if there's not cooling weather around it like now? Maybe worth to check the crankcase pressure to see if the oil pressure is ok?

I'll take a closer look tomorrow as well, maybe there is thermostat fitted somewhere.

Jeezuz - thank heavens my missus doesn't live where you do - I can't even imagine the wardrobe space we'd need...

Tsiko......


You just got a better one this time... ...... you`ll just have to lump it..

No hassle, don't worry, there's one very easy solution to all of the problems:

those low milage bikes who'd have'em

I think you're worrying too much.

mine gets up to temp quickly and stays there but never 'overheats' - even on a 42 deg day (ouch )
its supposed to get do that.

haven't tried it less than 8 deg C though

Probably need to try a different grade of oil Margus. Always did it when running the bike in UK and Ireland I used 10 40w, temps never really get above 21*C here . When I went to the Continent, in the summer where temperatures were in excess of 30*C most of the time , I ran 10 50w, to keep the bike at the temp it was used with. Unless its a blue printed engine, or it has been run in the same, it's never gonna run at the same temperature, given that they all lose sllightly different quantities of metal from their inner working parts, during their break-in period.....All down to the rider I'm afraid, and how useful he is with that right hand, in the early days. I fear I may stand corrected on this, I'm taking cover now, INCOMIN.!

Simplest thing would be to measure the temperature of the oil after a run.
Take of the bash plates to aid rapid access, go for a longish run to get the oil up to temperature, then drain 250cc or more into a plastic container, (to avoid heat loss), then drop a thermometer in.
Then cover the oil cooler and repeat the exercise.

Pretty sure my 1100gs has a oil thermostat,

the older ones didnt have one im certain, mines a 2000 (one of the last ones I think)

so maybe one of your bikes has one and the older does not?

if it works don't fix it
