    thats odd as they should have tightened up not loosened.

    +1 very unusual for valves to loosen with time
    are u sure you have felt properly
    u havent miss read feeler gauge sizes

    Not saying they CANT be bigger , just normally they close up as the valve / valve seat wears or recess a slight bit, thus bringing the valve closer to the cam.

    unless you have used very low grade oil and are wearing the hardening of the camshaft.
    but that would be a stretch and not very common , and I would have guest that u would have had other lube based probs before this if it was to be the case

    I say when in doubt recheck them again to be sure

    EX 0.32 - 0.41mm. I'm between 0.42 - 0.45mm EX.

    I use the mobil synthetic for motorcycles. I change oil every 3 rides.

    DEM BITCHES IS LOOSE... INSPECT FOR WEAR ON LOBES, LIFTERS, AND MAY WANNA SEE IF IT HAS BEEN 'MUSHROOMING' THE VALVE STEMS.

    Does that Oil have the JMASO friction modifiers rating?

    No. I was going to use this oil but didnt because it had no friction moddifiers. This is so it will work with wet-clutches on motorcycles.
