My high mileage GS LC has a louder than normal ticking from the left hand cylinder head. This was pointed out during the recent 12,000 mile dealer service, but no indication as to what was likely to be be the cause. It also ticks from the rhs but not as loudly. The bike runs perfectly and pulls like a train so it could be one of those instances when people simply suggest using a thicker oil next time?! I would still like to know if someone has had the same issue and especially if it’s been sorted (cheaply!) My buddy has a 2018 Rallye and that ticks too, but not as noticeably……thanks
