Today after work, I started my 2002 R1150R (21K Miles) and had a huge amount of oil smoke that lasted about 15 sec. Bike was sitting for 11 hours on the side stand on level ground. (First question, why am I working 11 hours).
I have had the bike for about 6 weeks and purchased it from a BMW dealer so it was professionally serviced. I did not get an owners manual so the posts on oil levels is good. the sales guy briefly told me how but it was not as detailed as it needs to be. I have observed no oil in the sight glass and that is freaky. Returns to normal after letting it sit.
At times during start up, the bike sounds like the bearings or valves are not getting lubrication. Sounds like a knocking and then it goes away after a few seconds. Is all this normal?
