Hello together, Micha and quite fresh here in the forum, My wife and I drive among other bikes also an LS 650. However, her oil needs, but I want to explain this more: Purchased last year with approx. 7500 km. 4 gear engine. Previous owner had removed the upper engine cover and removed camshaft and tilt lever with shafts. Why can’t I ask more since he unfortunately passed away. So we ordered at KFM a new shaft and tilt lever together with new screws Gaskets, stoppers etc. All built in and the first test run who top. Now she has Tüv and is registered, we made the first longer test drive. It starts badly has to start up to four times. Spark plug is new. Then when it runs it takes about half a minute then it smokes blue, which is gone again after about another minute. In driving operation nothing can be seen, while accelerating as well as in sliding mountain down there Qualmt nix. However, we are about 180 km dangerous about 200 ml we had to refill until in the glass was again on max. Of course with straight standing machine. Petrol consumption is also very low about 3.8 to 4 liters on 100. The engine has not yet run. Compression is at 13 bar. Have the valve shaft seals suspected. That it burns in the stand while turning on oil what is dripping into the cylinder. Does anyone have an idea or a guess what that could be??? Must the upper lid be removed again… d anke schonmal im vorräs
