Exhausts and Engine » Oil change, 2021 1250RS

Hi All...doing what should be a simple oil change, undid the sump plug, expecting it to just drop out, similar to the videos I've watched on YT, but it has a spring attached to it.

Is it mean to just drain around the plug, as I can't seem to get it free from the spring, or between the gap with the exhaust?

TVM...

That does not sound like the oil drain plug, hopefully you can screw it back in without an issue.
The exhaust is not in the way of a drain plug.
It is in the middle of the oil sump and is from memory the same place as all 1200 twins.

I can't find my R1200RS service disc but this is for the earlier R1200 "non-water colled models"

That is marked as Oil drain plug, M16 x 1.5 according to bmw service disc.

Check out this youtube, especially 3 minutes in - this is the drain plug, better than my diagram above.

( I would not let this guy change my oil but it does show the sump plug, and where to fit an oil filter removal tool, rather than a screwdriver, also fill with 3.8 litrs not 4, then follow chack procedure on a warm engine)

Thank you, I have indeed undone the wrong plug and drained 2 litres of something 🙄

I'm unable to post a link to the images I took, so now I'm unsure what I've drained...looks like oil 🤷🏻‍♂️

someone will know here for sure, my guess is either an oil pressure by-pass (hence spring) or if further back, gearbox spring return etc.

That oil will still be part of your engines 4 litres anyway , check in the morning for any global updates for your error and any likely impact.

all the best

Thanks Wessie, just took these.

Looks like no takers overnight for advice or an update which is normally the help given on the forum.

I think you have been lucky, if you can get something under the cap to screw it back in place against the spring pressure level without any cross threading.

According to my Haynes manual it is indeed an oil pressure relief valve spring and should push back in place without any further problems.

Getting a new sealing washer as per guide notes may not be possible but it depends on the clearance you have.

See photo of pages and the advised torque values ( I take no resposibilty for accuracy but these are usually same as a service disc from BMW)

Apologies for chuckling here.

A sump plug is BIG. Everything else is SMALL.

I expect the above reply is the answer - pressure relief valve for internal engine use only.

Find the plug, drain the rest. Refit plug. Fill oil. Ride.

Don’t fret about re-using a sealing washer occasionally.

Beware the dreaded Torque Wrench.

Especially into alloy.

Finger tight. Then a bit. You can always add a little bit more if it leaks.

You cannot undo a stripped thread when overdoing it with a big torque wrench.

....not sure if serious....

Please either watch a video or two of a modern liquid-cooled boxer oil change, or just let your dealer do it for you.

These may show the R1200RS but the 'oily bits' are the same anyway.

Well buggeration.

I've just got back from a long bike trip and only have a 3-week gap before leaving on the next one (yeah, I know, poor me) but I forgot to schedule in a necessary service between them and am now too late: so looks like I'm going to at least have to DIY an oil change before I go. Not a job I've actually done in decades, in my current 'born-again biker' status!

I've just watched Grumpy's video (thanks, Wayne) and I have a question... I can see immediately that the old chain wrench I've had in my toolbox for 40 years isn't going to cut it here due to access problems (plus these days I'm supposed torque up the new filter, aren't I!), so I need to order a new wrench. Can someone please point me at a tried-and-tested item which will definitely work with the R1250RS, and is available in the UK?

Many thanks.

Plenty of options, either BMW dealer (for an identical fitting unit at a higher price?) or the usual sites.

The bmw unit I got was a cast aluminium looking unit, some others are more of a presssed steel item.

Also you can order the bmw/Mahle oil filters (part number alongside the bmw unit confirms mahle origins) to make the postage costs worth it.

Nippy Normans will post it, along with oil filters , parts etc. www.nippynormans.com

Or Motorworks https://www.motorworks.co.uk/

Thanks Dave.
Am nowhere near a BMW dealership so looking for an online option...
Are these Mahle filters identically dimensioned to BMW ones? To be honest though, at least for my first oil-change I was wanting to stick with OEM stuff and am about to press the button on a 4 litre Advantec / filter kit.
Does anyone know if that NippyNorman wrench (https://www.nippynormans.com/k1200r/oil-...srtrrsadventure) definitely work OK? Cos at https://www.youtube.com/watch?v=O9jo7kyR2c0&t=143s Grumpy shows one which looks very much like that one and condemns it as "junk". Hence me asking for a specific tried-and-tested recommendation!
