    '83 GS1100E swingarm in a '78 GS750

    I searched through a lot of threads as many people have done this upgrade. I see most favour the bushing/bearing method as opposed to the frame drilling.
    I do not have access to these parts[helping out a buddy] so my question is...After the 1100 swingarm is installed will the stock 750 chain, axle and spacers work or will new parts be required to make up for any added length and width? The stock 750 wheel is being used.
    Thanks for any info.

    Pretty much all the rest should fit once the swinger is in the frame.

      Drillng is easy but take your time and let the bit pull itself through. A 1/8 inch misaligned on one side means the pivot could be off by double that comin out the otherside. Use lots of oil to keep the bit cool,clean and cutting. Needless to say if this is screwed up, you're in a mess. I used a wooden dowel pushed through the opposite frame boss to make sure I was aligned. A drill press would be best but a bit awkward. I think it was a 5/8s bit but double check that. You will need a longer chain.

        Hi Steve,
        Maybe you could use a 5/8'' reamer to enlarge the holes?
        A reamer work far better that a drill bit.
