Sorry, I cannot tell you anything from the recording. I did not discover my issue until my regular service interval at 24,000 and the valve to rocker arm clearance is checked. The service identified tolerances that were out of spec and then they pulled the cam shaft. Then they noticed the excessive wear on the rocker arms. With the Technical Advisory in mind/hand they concluded that the DLC on the rocker arms was exhibiting the criteria in the Technical Advisory... and then the Warranty was invoked. To be candid, I wear ear plugs 100% of the time when I ride and I did not notice any excessive noise. I suspect more noise is possible from a malfunctioning Cam Shaft Chain Tensioner, like I also had.
Hello guys,

Could you please check whether I "qualify" for the ticking sound of my bike. I've just recorded it but I'm not really sure. I hear some kind of ticking but I'm not 100% sure.
My bike is still in warranty and it is at 7700km.

I have obtained a workshop manual and found the location. Will have a look tomorrow to see if I have one.

Hi. New owner (2nd) of a 2019 F750 GS. I have been going over the bike and finding my way around. One thing has me baffled. An Alarm system is listed in the owner's manual. Nothing happens when I follow the instructions to operate in the manual. Has it got one even? If it does, where could I look to check? Previous owner had never tried to use it and can't help. Help appreciated. Enjoyed the first ride after 20 odd years away from bikes.
Maintenance and Servicing / Re: Air filter design flaw

You seem to know more than I do so I donít want this to be argumentative. I recall the BMW mechanic saying the newer models have a different air filter assembly. To me that indicates a design flaw. I am not able to verify this however so not sure. I would also say it seems hard to determine if the seal is good when you insert the filter plastic assembly. You can see the holes connected and and a good seal on the plastic tray but knowing it seats right once that assembly slides into the bike is another thing. I guess when the top mechanic at a large BMW dealer canít get it right then it seems like a design flaw. I really liked that bike and will miss it. I hope the pre-filters do the job. My dealer is pushing all owners to install those as a precaution.

The air filter doesn't have a design flaw per se it just requires a lot of patience and cursing to get it to seat properly.
BMW had a recall on this for some bikes as the filter was seated incorrectly from the factory.
The F&G series 650 singles were also a bugger to get seated correctly. I don't recall any problem with my 800 though.
Maintenance and Servicing / Air filter design flaw

I just sold my 2019 F 850 GS adventure. At 25,000 miles the valves were bent and I had to replace the entire head assembly because the airbox allows dirt in the motor. I did all of the scheduled maintenance at a local BMW dealer and since I was just past the warranty of three years much of the expense was out of pocket. The dealership did an amazing job going to battle for me to get BMW to pay for 2/3 of the cost. I discovered the issue when I was going through a lot of oil. I noticed it was a quart low after my last weekend riding in Moab. I went to start the bike and it wouldn't start after over a minute of cranking. I thought it might be the battery so I replaced the battery and I still had a problem starting the bike, but it eventually kicked over and sounded rough so I checked the oil and realised how low it was. after pouring a quart of oil in it was marking full on the dipstick. Realizing there could be some issues, I immediately took it in for the oil change, and the dealer told me the motor had to be replaced. Itís a real bummer also because I really like how the 850 rides off-road but I had to sell it because I didnít want it to continue to put money into this bike. It still starts hard even after replacing the head. After a lot of research, I now realize the design flaw of the Airbox letting dirt in and the workaround now is to put a pre-filter on the intakes to reduce the chance of dirt getting in the motor. So if you have an 850 and you ride off road, be very cautious and see if you can get the upgraded airbox that they are putting in the newer bikes. Check your oil more than you think and if you are starting to burn oil, sell your bike as fast as you can. I will now use a pre-filter on my 1250 GS just to be safe but it does not have the design flaw so it is not as common of an issue.
Maintenance and Servicing / Re: Timing chain tensioner defective

Well, I did manage to change my tensioner.

New one didn't really feel any different from the old one, but let's hope the new one keeps the oil in it at least a little longer.
Old one was completely empty of oil after sitting the whole winter.

Oh, and before the first start I hit the ignition just short enough for the engine not to start, and repeated this for a few times, to get the oil at least somewhat circulating and closer the the tensioner. No rattle on first start.

Bars fitted. Battled a little bit with the LHS bottom mounting plate, but otherwise fairly straight forward.

Spent some time at the dealer.  The emergency bracket is set up for the GSA.  The GS can be retrofitted but requires an adjustable windscreen mount and the plastic screen cover.  The GSA screen cover even has a different shape so the bracket can come through.   Surprised the dealer.   He didnít know about the difference and thought it was the same.  Said he learned something new.   Thx everyone.
Interesting. Sounds like a good opportunity to get the adjustable bracket. All 850GS from 21 and up got the adjustable bracket as well btw, so maybe you could find a second hand one.
