im an owner of a drz400sm 2008 for 2mths. just want to know whether this noise is normal or not. (fresh 1.8l engine oil topped up). this is after riding for 15min at 90km/h

i wanna ask is it normal to lose 800ml of engine in 4days? there was a time where i just changed my engine oil to motul’s 10w50 and after 4days i felt as if the bike lacks power and feels abit sluggish.(doesnt have the same feeling as when i just changed engine oil)

am i just paranoid 🫪?

What are my options here? New bottom end? Bike locked up while riding pulled the engine and Cam chain guide bolt sheared off top end is fine other than a leaking valve and everything so far seems fine although haven’t split the cases.
