Hi Guys, I have a 2007 990 adv with 76k KM on the clock, cam chains were replaced at 50k but not tensioners (dont know why the dealership only changed the chains and not the tensioners at the same time, or guide rails). Oil pump was also replaced at the same time. I have had the oil light flickering at idle for around 15k now, my oil pressure switch started leaking and replaced that with no difference to the flickering oil light, I saw one wave on the oil filter at last service so have purchased the water pump rebuild kit and will be doing that shortly as suspecting that is also on its way out. The bike is sounding noisy now, sounds like cam chain noise and feeling rough \ vibrations from the engine. I just want to find out , can the tensioners cause the oil light to flicker \ low oil pressure and therefore the cam chain noise? Im assuming yes because if they are faulty they wouldnt allow enough oil through? Thanks!
