getting very hot

[DaiB]

hi folks as you can see iam new on here hopeing someone can tell me if this is ok two weeks ago rideing my 1150gs 02 model in spain got stuck in a bit of traffic stop start the oil temp gauge shot up in the red the outside temp was about 28c is this normal many thaks in advance Dai.

Hot

Ride above the Artic circle or put it on E-bay>

No, this is not normal. Mine always stays midway, even when in sunny spain. I guess the obvious is to make sure you have enough oil in her. Did the bike still run 'as normal'?

Make sure the thermostat is doing its job, check the hoses to and from the oil cooler they should be hot when the engine is over normal temp...
...but due to the engine design it will get hot in stop/start traffic without a flow of air over the cylinders. 4 - 6 bars is normal and I've had up to 8 bars in British summer.

Hot

Check the themostat as above this is liokly to be the problem, and make sure the cil cooler is not full of debries. I have ridden mine through several
deserts including death vally and it never went more than two (very occasionally) bars above normal.. Check the hoswe tempratruer as above this will tell tyou what is happening how's the oil level?.

Going into the red is never too good,but as these old tubs need airflow to take the heat away rather than rely on fans there will sometimes be a problem.Mine got too hot while i was setting the TB balance and started to smell funny so i just turned it off until it cooled.Check your oil level and circulation just in case,but if its happened only once,dont worry about it.

My bike did that a few times in traffic in London and I did wonder a couple of times if I was going to ahve to get off and pee on the cylinders to cool it down (okay, not really, but I did think about it).

The other thing to check, along with the good advice above, is the grade of oil that you are using. I found that shifting to 20W-50 or 15W-50 from "the usual" 10W-40 helped. Check the manual for the correct grade for the temperature you are experiencing. Better for the engine anyway...

hot

thanks everyone i had not long bought the bike the shop serviced it so thay say but thats another storey. so dont know wot grade oil but the level was a bit low did smell a bit when this happened but cooled down quickly once i started to move quicker put about a mug of oil in her no probs after that well its haveing a proper service this time so lets hope thats sorted it thanks again all .

Glad somone finally mentioned oil grade. I also changed to 20/50. Much better. Whilst in South of France in summer temp only raised by one bar.

My biggest problem was in deep sand in 35C plus, serious high oil temp DUE TO WIDE OPEN FIRST GEAR NO SPEED, this makes city traffic a joke??? The result was a tick over at about 2000, 2500, this made riding extremely difficult??? Any ideas I thought overheating throttle bodies??

Anyway didn,t stop since that just raises temps and once it cooled say 10 mins of more open riding it was OK...

Not wanting to piss on someones battery, but an oils grading is its temperature range for protection and viscoscity over a temperature range, it has naff all to do with its heat transfer coefficient, so the grade versus the reading on the temp guage should have no effect (actually the lower viscosity should have a higher velocity in the radiator and therefore a better heat transfer) please correct me if I am wrong?

The BMW handbook (as I recollect) shows 10-40 oil as being suitable for a lower ambient temperature than 20-50.

That is what I said, it achieves the lubrication requirements, but it will not have a different cooling characteristic, remember these are oil (cooled) heads for cooling otherwise they would be airheads..

Fair comment, educated me. Thanks
