Auxilary oil tank
Would any body have any just or impediment reason why a 1ltr auxilary oil tank cannot be mounted, say on the top of the crash bar of the R80G/S models utilising one of the oil filter radiator outlets with the two oil pipes mounted to a customised oil tank. The feed entering the top of the auxilary tank and the return pipe to the filter housing being mounted to the bottom of the auxilary tank, I would think a one way automatic valve would be have to be fitted in the return pipe to hold back the oil in the tank to stop it from flooding the sump.

Looking at this I do not see any reason why this cannot work.
I would be interested in any feed back,

regards to all Mike the bike.

Why would you want to do that? does the oil get too hot? is it using excessive amounts ?

Easier/simpler/better to get a sump spacer ring. Increase your capacity by 1.3 litres... more than 50% increase.

If you have an oil cooler, fit a thermo unit on the engine outlets.

Would that not affect ground clearance...?

I think it sounds like a lot more hasel than it's worth. Another litre isn't going to dramatically increase your oil life.

An external tank also leads to the risk of losing all your oil in a crash if the pipework or tank are hit.

Plus, your oil pump is calibrated for your current design. Giving it another tank and more pipework to push through could stop it pushing oil to where it is really needed. You would get a drop in oil pressure.

Just my thoughts...

Not significantly. Most marks on a bash plate come from flying rocks. Lots of people have fitted them.
The increased volume is good for hot climes but I would still put the thermostatic oil cooler connection on.

Spacer-ring affects groundclearance.
If you are concerned about that - do not install the spacer-ring. Your idea is in that case better.
Which frame do you have?
I know guys welded the central tube under the tank shut on the pre-85 modells to obtain an "oil-tank". You could also modify the crashbars. I have mine filled with waste oil. Another way to go is dual oil-coolers, Setrab or similar hydraul coolers. You could also use Terry Phillip's Spin on Filter manifold using any oil-filter as an external oiltank (my VW Type 4 have a 1.2L oil filter if I recall the size corretly). BMW motorcycle accessories

I have landed on my oilpan a couple of times, before I installed a spacer Ring from Wüdo.... To keep best clearance I changed the oilpan from the 2.5L to the 2.0L => 3L incl oil-cooler works ok, but I would not ventrue off-road with it...

Thanks a lot for the information Albert. As usual you are the only one to give a positive answer to my ideas, all the rest are always don't do this or that, why bother etc. There is always room for improvement, especially on BMs.

I have always found ways to improve on a certain designed machine which is lacking in the modern ways, as is the way with my 1973 TRIUMPH DAYTONA 500: spin-on oil filter, electronic ign with a Honda cbr dual output coil, high output alternator with a Suzuki reg/rectifier, American bd valves and guides,racing type front fork internals and I have to tell you it holds 6.2 pints of oil. A lot more than the g/s, and by the way she has covered more than 200,000 miles with out a break down and that includes many trips around Europe.

Anyway I will proceed with my origional plan and install the oil tank, probably on the top rail of the engine crash bars,

again best regards Albert and safe riding to all the negetive heads, Mike.

Now now Fairy Twinkle Boots, evan human excrament is useful.
I really cannot believe some of the daft feed back on these so called tech sites especially by people who are clueless regarding basic mechanics.

Also the oil pump will quite easily acommodate the oil tank, don,t forget the same pump pushes the oil through the oil cooler if fitted. I beleive Scriminger utilise external tanks for some of their mods.


Nowwww site back and reeelaax, deep breaths everyone.

Would that not be for their aero mods though? I would have thought a dry sump system would have been good for that use.

But, back to your original question... Why?
