Updated, see my following post. I’m not happy after spending $655 on a service.
Please advice on what you think is most likely cause. See photos.
Had my 2023 R1250 GS into Iron Horse BMW in Tucson on Saturday (trailered down 225 miles from Prescott Valley). They are closed today, so I ask in MOA first. They did the 24k service. Bike bought there and always serviced there while under warranty. Only rode it 30 yards from their back lot onto my trailer and then 20 yards from the trailer on the street into my garage on Saturday night. Parked it. When I came back to house after going to post office today I noticed oil below. And oil sight glass shows a bit down (I know this is not a problem for the engine, but every other time they service the oil is at top of red ring). They also said the Cardan failed the test/inspection and they replaced the Cardan shaft. You can see a drop of oil at back edge of lower engine guard. Assuming they take the lower engine guard off to change the oil, it would seem this leak must be coming after they put it back on. I feel no oil leak at base of oil filter. I will remove the lower engine guard and take a look. Crackcase drain plug or front end of Cardan shaft area?


What say ye? Thanks.
