Hi all
My 2011 Rt has suddenly started doing a different engine noise and it gets stronger after it rides for some minutes, it starts around 2000rpm and it also seems to be vibrating slightly more, not much but noticeable
Around the same time this happened the oil level alert showed on the display and after checking the eye glass I noticed it was empty, bought oil immediately and it took one litter to level almost to the top of the glass
Bike now seems just slightly less responsive on low and high revs and apart from the different noise what I really notice is that it has lost a lot of engine braking when decelerating, I am used to slow it down with the engine and now it takes a long time to lower the rev's so I am sure something is not right
A mechanic friend of mine assured me it's not the crankshaft, connecting rod or piston and the bike makes no smoke at all. He said it might be some faulty cam tensioner that missed a step but without certainty as he is not acquainted with these engines
Temperature is fine too and hasn't over heat
I called BMW and they told me it is strange but shouldn't be related to the oil level as it is common for these engines to loose 1 litter between checkups, I asked if it could a faulty spark plug and they said not very likely.
Up until now the bike has been fantastic, never had an issue and it pushed really well.
Just wondering if anyone could shed some light on this problem before I take it to BMW for diagnostic ?
I made some videos of the problem
