    You should add your bike model to your signature -
    But, most XJ's are .11-.15 intake, .16-.20 exhaust

    Specs for the crank? different for some models -
    Main clearance: 650RJ .020-.044 All others .040-.064
    Big-End XJ 750 .016-.040 all other .03-.09
    Main journal runout .04

    Now exactly why some tolerances would be about HALF of the others is beyond me.
