    Just checking in to see if anyone has done their own valves on a 2020 or newer bike if so is it the same as a 2019 and older and if so will Mark's book work as a guide or is everything different are the valve specs the same as the GEN one bike coming up on my 18,000 mile service that I usually do myself but I have always had a service manual to give me the particulars any insight would be helpful thanks

    Completely different engine between the Gen-1 and Gen-2....not even close. The Gen-1 cams and camchain spin backwards...Gen-2 is normal rotation....although they do use similar valve actuation rockers & shims etc...I don't know the Gen-2 clearances though...one would imagine they'd be similar. :027:

    I find it hard to believe no one on here has done a valve check on their own I have never had good luck taking motorcycles back to the garage to be serviced not only  does it cost a lot but every time I have taken it to the garage to be serviced they messed stuff up stuff they weren't even working on

    Don't forget the Gen 2s haven't been out that long and the majority of people wont do 18k miles in 2 years, and the majority of those that do, will just take their bike to a dealer.

    My dealer told me that BMW stopped providing them with maintenance DVDs to sell customers. I don't know if there are any newer ones circulating still but if not, that will make servicing the new bikes nearly impossible.

    I'm seen few people with 18k miles and over. However, when I ask them if they've done it, they say no. "If it's not broken don't fix it". However it might be too late for that if you hear them. I don't know it's hard to tell.

    I did the valves clearances on my Gen 1, then I did a leak down test and two inlet valves were leaking. It seemed to be running fine before that. Me being me though could not leave it like that :-D

    I did mine at 25k and even with an exhaust with no tune they were in spec, albeit a couple were at the edge of their spec so I replaced them anyway to bring them further to the middle.

    i have a 18 Gen 1 with 24k. To date I have not re placed my fork oil or valve shims,  I have had numerous discussions with BmW techs and they state that if you have problems starting or a noise appears there should be no reason to add £sss to your service costs.
    The front fork oil will not degrade to a level of to cause trouble.
    If you track your machine or stretch the engine then of course consider the valve service.
