    On topic but a different bike....

    I just had the 20k km check done on my Aprilia RSV4. For those who don't know of this bike it's a V4, 200+ hp sport bike. All valves were in spec but at the tighter end of that spec. They were adjusted to the middle of the specification.

    Taken in total, I think this thread is telling us that manufacturing design, tolerances and materials are much better than those of the past.

    "They sure don't build them like they used to!"

    Valve clearance checks

    Hi my 2020 RS had the left side checked and adjusted by the dealer at 4k after I complained that it was noisy. At 12k I did a check on both sides and ended up changing 2 shims on the exhaust on the right side left was good.These motors are noisy especially the left side.

    I did my valve check at the 12,000 mile service; all within spec. I skipped the valve check at the 24K service. Will do the valve check at the next 36K service and adjust if necessary. I have all the tools, etc., for adjusting valves and aligning cams.

    I do a lot of service on different bikes. I always recommend checking valves and timing at 10,000km. Turns out all but one out if 15 bikes I have done the timing is out and often the cam position sensor. About half the bikes the valves are ouroff spec and need shim adjustment. Both truly improve how smooth the engine runs and it seems to improve powere, seat if pants assessment.

    Have 96k on my 2017 RT-P, and 56k on our 2018 RT-P. Both get serviced like clockwork at 6k intervals at the BMW shop. Neither of them has ever needed an adjustment and the tech tells us it's rare they need to adjust on any 2015+ RTs coming in.
