#1 | Loud clicking on LH cylinder when engine hot. datum

Hi,

I have a 2019 R1250RS with 17,000 km on it. At about the 12,000km mark the engine developed a loud clicking sound on idle on the LH side. Only when the engine is at operating temperature.
I have noticed recently that there is also a distinct rattle upon initial acceleration from lower revs. These noises were not present pre the 10,000 km mark.
I have seen on Youtube reports of the same issue with some saying they have had cams, heads and in one case an engine replaced.
One guy had success with replacement of the cam chain tensioner on the left hand side.
Has anyone else had a similar experience as it seems to be a common issue?

I follow the UKGSer forum. I'm not seeing many problems. I found one instance of a left ticking noise fixed by changing the cam chain tensioner under warranty. Most faults on the GS shiftcam bikes seem to be related to the Hayes brakes you don't have and the stupid colour telly that refuses to talk to various other devices.

I have friends with a 1250ST and 1250GS. Both report a "tappy" left cylinder. Both will be relatively high mileage bikes.

The GS owner has been told by BMW that it is the decompressor rocker clearance opening up when it's warm.

The only issue I have with the your mates dealers explanation is it never happened pre 10,000km and it seems to be getting progressively louder. I will get it checked at the 20,000km service and see what they say.
