    Fuel in port valve test - how tight does it have to be?

    Fuel in port valve test - how tight does it have to be?

    Putting the head back together after lapping etc. The Suzuki test of fuel in the ports had, on the intake, initial slow leak that stopped. On the exhausts, no leak only seeping (an I can only tell because the tiny bit of carbon I couldn’t get off around the valve got darker.)

    left the gas in tehre a half hour. nothing else dripping or seeping. Fixed it self?
    1981 GS750L - Owned since 1990 when graduated high school and since have been discovering all the things not disclosed by seller.
    1983 GS750E - bought in 2016 as a rough runner to use while rebuilding 81L and then to combine with ES to make one good one
    1983 GS750ES - bought in Toronto in 2015 on a lark as a non-runner, missing front cowling and exhaust - If you have a 1983 750ES front cowling let me know! Blue would be nice
