    Am I reading the service schedule correctly? No valve gap check for 2022 T100 until 20K miles?

    Yes that's correct. It applies to most of the modern classics, including the Speed Twins and Speed 400

    Amazing. I won't put 20K on my bike in five years or even more. Will warranty coverage for burned valves expire after two years? I wonder if they have data supporting such a long service interval for valve adjustments.

    Those of us with long memories. Remember near constant care of valve lash. Except on my Honda VF750f. I just replaced the cams at regular intervals. It is a thing of the past. I think that proper service allows the extended valve inspections.

    I'm 73. My experience is mostly cars where yes, hydrolic lifters, no worries. But, no matter what Honda says, my 2003 Honda S-2000 needs valve gaps checked once early in its life and then every 10K or so thereafter. The consequences of tight valves are too great. I have a 2022 Royal Enfield that is similar.

    I guess I would feel better doing a check early just to be sure things are ok.

    It does worry me that they have the first check after the warranty is oftentimes expired.

    Both my 2020 & 2022 Street Scramblers had 20k valve check intervals, as does the new 1200. I had the lid off both SS's around 8k to check the clearances and some did need adjusting, more so on the first one. They weren't actually under spec but very close. Wether they'd have lasted another 12k is difficult to say as valve clearances tend to move in the first few K and then settle down IMO.
    Irrespective of scheduled maintenance intervals, I just like taking things to bits wether they're working or not, just to see how they work.

    To an extent, yes. I am with you there. Frankly, I am not all that confident that the valves leave the factory properly adjusted, so its probably a good idea to check them at least once early. Maybe even at the first service.

    I checked mine at 5000mls.....I was looking for a cold start tapping noise.....valves where fine.

    Exhaust where toward to upper limit....which is fine as the gap closes as wear takes place.
