    A picture is worth a thousand words! I found this in the Husky TE-630 repair manual. Why couldn’t SWM just have added this one pic and paragraph?

    That's a much better explanation than the Swm instructions. Now see if you can find a detailed instruction on valve checking and adjustment.

    However, I think the SWM manual says 0.10-0.15 mm for BOTH intake and exhaust clearances. This is different from the TE-630 specs.

    Out of curiosity: has anyone taken the 3rd filter out and found any significant deposits?

    I'm not gonna do it bike is too dirty and just did oil change but will ask dealer in Osh along with adjusting valves.

    Kimokk, Thank you for that. This will make it easier to maintain the bike after the warranty runs out. I just need to buy that spring tool.

    these are the indications on the valve clearance for the RS650R and are identical to those of the TE630. the minimum value coincides with that prescribed for the Superdual. DISTRIBUTION

    in my opinion they report the minimum value below which it is not recommended to go down. a valve with "too much" operating clearance only creates noise. a valve with "little" backlash lower than the values indicated by the manual 0.10 and 0.15 can cause serious damage to the head. also consider that usually with increasing km the game decreases and rarely increases

    Considering the rs650r and superdual are the same engine there are certainly some discrepancies in the information being provided by Swm

    E.g engine oil
    Rs650r 2016 requires Motul 5100 semi synthetic 10W50
    Superdual 2017 requires Motul 5100 semi synthetic 10w50
    Superdual 2018 requires Motul 7100 fully synthetic 5W40

    These are the same engines with the only difference being euro 3/4 compliance.

    @Tarmac Teaser

    Can you ask your dealer what the specs should be? The dealer here in the states told me they haven’t been given a service manual yet from the company or importer.

    Are they using the same valves/material? The reason exhaust valve clearances are higher because they run hotter and expand more.

    IIRC SD used titanium valves on one side and Ti has a different expansion coefficient.

    EDIT: yes Ti thermal expansion rate is ~1.5 times less than steel so if exhaust valves are Ti same clearances would make sense.

    My dealer is useless unfortunately. If you want to be on the safe side set them at 0.15mm each which will keep them in spec. I suspect if I put the bike in for a valve adjustment they would use the 2017 model specs. There is no service manual currently available to us for the superdual 2018+ only the owners manual.

    Good info, thank you for posting!
