  • DIY Tire replacement

    I've decidd I'm ready to try doing the tire replacement and balancing myself on my '80 SG. Done enough dirtbikes, I feel I should be able to acomplish the same thing with my street bikes. Have a question tho, about the brake discs. I know they're very fragile, and I don't want to do any damage while fighting with installing the new tires. Does/has anyone just removed the disc(s) from the wheel prior to removal/replacement of the tires? I imagine it would be a good idea to mark them, so I put them back on in the same place, but what do you folks think?
    Nothing like a ride on a straight 4.

    I wouldn't think rotor removal is needed. I would, however lay some thick cardboard or, an old blanket on the floor to protect the rotors. The 80 SG has slotted rotors, and they are stamped R or L, so they won't be confused, and there only 3 positions they can be installed. If you have dirt bike experience, then the XS shouldn't be much of a problem. Just don't go wailing on the wheels with a hammer.

      I haven't tried this myself yet, but here is a pretty good article on changing your own tires. Motorcycle Tire Changing

        I used a 14 inch tire rim with a split air hose around the bead for protection. The rotors fit into the rim and never get touched. To break the bead put 2x4 under the rim on either side to keep rotor off the floor.

          yeah, I figured that would work, but I just wondered if anyone had ever just takken the rotors off to avoid possible accidents. Of course, I suppose if I went to all that trouble to take care of the rotors, they'd end up falling off the workbench and warping or something like that! lol I suppose I'll just stick to what's worked for others, and take my time... patience. Saves me every time I exercise it.

            I've never worried about the rotors, they are made of steel plates afterall. I've changed a number of tires by just laying the wheel on the back steps. Sometimes I have to use a bead breaker to get them loose though.
            BTW, I found a cheap place to get tires, at the local Harley dealers. A lot of Harleys use the same size tires and they usually have some nearly new take-offs for $25 or so.

              I usually only work with the wheel sitting on an old tire not to save the rotor but to keep it from rocking when I'm woking the irons. If you do scratch the rotors, the pads will shine them back up.

                To make life very much easier, pick a sunny day and let the new tire sit in the sun a while.

                Goes on MUCH easier.

                    I use a 20 gallon oil drum
                    with the top cut off
                    put some hose around the edge to protect the spokes
                    the brake disk should fit right in and the outside of the barrel hits aganist the spokes
