Re: New Owner - Valve adjustment?
When the bike was sitting for longer, checking all the things and settings like valves, plugs, camchain is a good idea. Also replace air filter, oil and oil filter. Engine noise may in fact origin from the valves, however my first look would be the cam chain. There is a semiautomatic tensioner, you just release the 10mm closed nut at the rear center of the cylinder bank a few turns and tighten it again while turning the engine by hand at the crankshaft right side with a 24mm wrench or socket. Sometimes the tensioner is blocked and it helps to release also the upper bolt (just a bit, you probably won't get it in again otherwise!) just above the adjuster nut which is the second mount of the tensioner. Cam chain tension can be directly checked best with a screwdriver when the top center engine cover is away e.g. for valve adjustment. The valve settings are quite tight, 0.05mm intake and 0.08mm outlet.
What you really want to have before you start is probably the online manual where all the procedures are described with pictures:
Don't hesitate with further questions.
Looking forward to the photographs.
