  • Fixed seat design flaw

    Well, the XS is coming up for 29 years old next month, so I set out this afternoon to fix the design flaw that has been hanging over XS1100's for 29 years.

    To get to the toolbox on mine the seat must be removed to remove the sidecover to gain access to the toolbox. So, just remove the seat????? But the spanner is in the toolbox!!! Thanks Mr Yamaha, real bright. Yes you can force the seat up to get the sidecover off but since it's now 29 years old and getting a bit rusty then the seat damage could be fatal.


    My solution:

    Went down the the pushbike shop and picked up 2 of these quick release bolts.


    Nuts were know good so I found a piece of steel and drilled and tapped some threads into them to act as new nuts. (Aluminium would possibly be better) Steel was the perfect width to prevent internal turning. The shorter the better to allow more sliding movement.


    Then it was fit to my spare bike to measure and cut off the XS (excess) bolt length. I used a few spacers to keep it out in the open for final pics, but it could be used without to conceal the catches better. A little extra length to start with doesn't hurt.


    Refitted the brackets to the seat. Note: they are only small bolts so if yours are rusty be VERY careful removing them.


    Nothing left now but to fit to the bike.


    I think it looks good and will be much better. Can finally put some tools in the toolbox without carrying a spanner in my pocket.


    Total cost: AUD $15 for the quick release bolts
    Half an hour in the shed.

    Cheers

    PS Yes I am hunting for a new seat pan to recover. May get a fibreglass one made I think.

    Very nice!!
    I don't like the bolt-on seat of the XS1100. The latch/side/flip seat of the XS triples isn't much better if you had a rack and/or trunk.

      Great! I have been thinking of doing the same thing for some time but wasn't sure of the thread size on the quick release. I didn't think about making new nuts. Great post.

        i dont ever have a problem because on the 80+ models, the side cover has the round holes that make it easy. Why did Yamaha even use the 78 79 mounting tabs at all. The round holes make it soo much easier.

          same thoughts

          Maximan suggested doing something like this when I talked to him this past summer about the FD mod. That is a good idea and will catch on quick. I think it should be immediately put in the MODs forum.....hhhhhmmmm.......T.C.

              The PO of my bike thought removing the seat bolts was such a PITA that he always kept them loose. I didn't think that was so safe and don't mind getting out the ratchet and extender. I also don't have a problem getting the side cover off. But the quick release bolts do seem like a great idea.

                          Aww Shucks, Thanks fellas, I'm now in the immortal area of the tech tips. (Insert :blush: smiley)

                          On a good note, the only thing I was concerned about was them vibrating loose, but with approx 100 miles under the belt so far there is no sign of it. If anything they get tighter
