Any body know recommended oils for engine/ gear box/ final drive for the K11??

You have been warned. Your oil can be too slippery.
I use these synthetic grades in all my 8 and 16 valve K's without any issues. My K100 track bike has been mercilessly thrashed on track days often up to the rev limiter and all's well. Gearbox and final drive also good.Kaptain Holister wrote:Aww no!! Not another oil thread.... Someone had to say it

BMW do recommend synthetic engine oil and I think issues like sprag clutch problems are caused by using a mineral oil with low detergent.
I saw that, and wanted to warn anybody who might think that putting it in the engine is a good idea.92KK 84WW Olaf wrote:Point-Seven-five wrote:Just don't put molybdenum disulfide in the engine. It will kill your sprag clutch. DAMHIK

No, it went in gearbox and final drive....

I made the mistake of using Honda Moly 60 as an assembly lube when I did my cylinder head. After an hour or so of run time the sprag stopped working. I had to do a backspin to get the engine started with a full can of Seafoam, let it run for a half hour and did an oil change to get the moly out.

agree BlakeyblaKey wrote:"Close this discussion as soon as possible, please. It never ends well.
Just buy something reputable and slippery and change it regularly; your bike will love it."
^ This.
I will add...use oils to suit the climate where you live and the temperature you will encounter before your next oil change.

I would recommend 20W50 this is better for hot temperatures, I don't think anybody will use the bike -20Celsius
GB/FD Oil: Nulon Synthetic 75W90
this is the 30Years old BMW recommend oil, the modern equivalent would be SAE 75W-140 API GL-5

this is the correct stuff, I use the same :-) It runs perfect, but you have to fill up more often!

Need to watch that black stuff. It can burn the exhaust valve and tailpipe if you run it too rich.
Was so...Corkboy (post No.12) mentioned the T word. My simple mind was unable to contemplate the magnitude of an oil and tyre discussion in the same moment of consciousness so I failed safe and "disregarded the post" - until now.92KK 84WW Olaf wrote:He looks well oiled anyways......
Look what this talk of oil started....!!
Just as well there was no mention of tyres.
A little harsh Dai...it's been a long day and he is obviously tyred and, whilst (lucky b'stard) he is not balding, he may still be losing his grip.Dai wrote:SHOOT HIM!!!!!!!!

I'd agree Choco, its maybe a little low in viscosity but the K is an over engineered machine with fine tolerances, polished contact surfaces, hardchromed crankshaft journals and nickasil bore linings etc. From what I've read it can handle a quality modified synthetic 10W40. Just my opinion. She's due for a change now and I'll be using same oil but in a 15W50
GB/FD Oil: Nulon Synthetic 75W90

75W140 gear oil is a much higher viscosity oil not suitable for general road use. Its used in drive trains under excessive load like trucks. This viscosity in a BMW drive train would produce higher than normal running temperatures with greater drag and a marginally lower power output. Bearings would suffer due to reduced oil flow imo. 75W90 is the correct oil to use

Just my 5 cent

20W50, 10W50 or 10W50 is a question of temperature where we live. In the end they are all OK

I'm not sure with this, in the German forum they all recommend SAE 75W-140 API GL-5 as newer and better oil then the 30 years old BMW recommend 75W90.

Why isn't it a standard additive for final drive oils is the question (niche market!).
Oh yes there is an advantage. In cold weather a 5w50 will circulate the engine much quicker than a 20w50 will at start up. when warm they will both be a 50 so the same.jbt wrote:There's no advantage for using a low viscosity index -below 20w50- unless you're riding under -10°Celsius (15°F). Who does?
