    Default Forks 1981 Harley sportster

    Does anyone know the installed height spec for a 1981 Harley xlh front end ? Would it be .50 ? Also does anyone know the factory specs to torque pinch bolts ? Putting fork boots on just want to make sure they’re out back on right. Thanks

    Not sure what you mean regarding installed height spec with your question of; "Would it be .50 ?"

    .50 what? inches, mm, feet, meters?

    and .50 from what to where?

    what size, pitch, and grade are the pinch bolts? Just look up toque specs for bolts:

    '81 front forks have tapered tubes which socket into the top tree, and there is no height spec.

    Methinks you are dealing with a later fork, with pinch bolts on the top tree? If so, on a standard XL, those tubes extend about 1/8" above the top tree, and you can adjust upward from there if you want to change the ride height.

    Eyeball photos of the stock bikes to know how it will look. Stats don't tell you that.

    Get a factory service manual and parts book. Downloads will do but tech data is gold and the best tool you can have for your Harley.
