    I just found your web site and joined right up. I ride a 90 FXRS Lowrider that just hit 95000 miles!
    Found you guys while looking for info on the 5 speed trans. I just lost the spring that returns the shift lever inside trans. Does anyone know if you can fix this without removing trans or does it have to come all apart? Its been to long since I had one of these apart. lol
    Thanks for any help. Ted

    Welcome to the forum. You really should have a service manual to do this job. Inner primary, trans. top and right side need to come off/out. A couple of special tools are required. That spring broke because of the sharp stamped steel edge on the shift mech. Make sure you file that edge off.

    Welcome to The Forum
    if you have no other obvious reason to take the inner primary drive apart,
    then leave it alone. Takes too much time and too much potential for creating
    a problem that doesn't currently exist.
    extract the transmission top cover and whatever else is in the way of it.
    If the starter is in the way, just blow the two bolts holding it to the
    inner primary, pop it loose and rotate it clear of the trans top. If it's a
    softail, unbolt the oil tank and swing it out the right side. no need to
    drain it nor disconnect any lines.
    next yank the exhaust, clutch release cover, shift drum, forks and fork
    shaft.
    unbolt the door from the trans housing. Remove the nuts from the main and
    countershafts.
    now heres where the special tool comes into play.
    It's a crossbar that bolts to the trans door and pushes the main and
    countershafts out of their bearings. You can use this tool to extract the
    door and bearings from the shafts and transmission. The bearings will need
    to be replaced after this is done.
    remove the spacer, first gear, clip and shifter clutch from the main shaft.
    At this point, the countershaft in it's entirety can slide right out of the
    transmission.
    now move to the shifter. Unbolt the shift rod from the trans shift arm,
    remove the pinch bolt from it too.
    make a note as to the position of the arm relative to the shaft so you can
    reinstall it in the correct location on the spline.
    slide the shifter arm as far off as it will go, then reach in with a pick
    and grab hold of the circlip, and rip it out with wild abandon. Now you can
    pull the shift shaft inward and free of the bushing.

    Install the new spring, and stuff it back in so the shaft barely protrudes
    through the seal.
    with deft precision, use a 90degree snap ring plier to install the snap ring
    about 1/4 inch onto the shaft, then sneak the shift arm back into there,
    then push the shift shaft the rest of the way into place, push the shift arm
    onto the shaft to slam the cirlip into place then reinstall the pinch bolt.
    now, reinstall the countershaft and mainshaft parts , replace the bearings
    in the trans door, then use the shaft end nuts to pull the door back onto
    the transmission.
    Reassembly is the reverse of
    disassembly at this point.
    remember to look for the piece of spring that came off when it broke, and
    check the teeth for bends.
    If you recover all the spring parts with no dents in them from going through
    the teeth, you're fortunate. There is an updated part number for the spring, hope you can remove all the broken spring pieces Good Luck
