    Rear Suspension replacement 1981 gs750L NEED HELP

    So I just received my after-market rear suspension in the mail (http://www.ebay.com/itm/390671335818...%3AMEBIDX%3AIT) and there are many problems with the fit. They are the right length, but the clevis end hole is only 8mm while the hole on the frame/ bolt that goes with the old shock that I was going use for the new shocks is 10mm(1cm). Also the clevis joint that came with the new shock doesn't fit over the "female" part that it connects to. Should I just force it over? Any ideas on where to get the right size clevis end?

    The link you supplied for the shocks says they are not compatible for GS750L. You've bought the wrong shocks (they're crap, anyway).
    Current:
    Z1300A5 Locomotive (swapped my Intruder for it), GS450 Cafe Project (might never finish it....), XT500 Commuter (I know - it's a Yamaha :eek:)

    Past:
    VL1500 Intruder (swapped for Z1300), ZX9R Streetfighter (lets face it - too fast....), 1984 GSX750EF, 1984 GSX1100EF (AKA GS1150)
    And a bunch of other crap Yamahas....

      oh man I just now saw that function. The only think that isn't compatible is the clevis end, which I thought would be an easy replaceable find. I know that are of china quality but they are about all I can afford. Any suggestions for cheaper shocks that would work?

        The clevis ends on those shocks have a history of busting. I wouldn't attempt to force them on.

          I just looked up what a set of Progressives would cost me and they would set me back about 270$ which is money I just dont have. Any suggestions for alternate brands?

            You've already spent money on these ones, why don't you see if you can make them work? increasing the bolt hole is simple enough if you have a drill and the proper size tap, or just drill right through the clevis and use a longer bolt with a nylon nut or a lock washer. How much difference are we talking with the clevis? a few millimeters should be easy enough to sort out with a file.

                  Emgo's are cheap and decent enough, but the eyelets are crap and the springs are stiff. Some of the bigger folk find them serviceable enough, and basscliff has a tutorial on how to change out the eyelets.

                        For something you don't have to mess around with and will work quite well (and is cheaper than Progressives), contact Dave Quinn Motorcycles at 203-393-2651. He sells IKON shocks, which is the modern version of the old KONI shocks. They are about $215 or so for the pair. Dave will talk to you for a while to determine your bike, your weight, your riding style and the frequency of passengers or other cargo to determine damping rate and spring rate. Very pleasant experience, quick shipping, very happy with the product.
                        I ride many bikes.
                        Some are even Suzukis. :D

                          I put a pair of these shocks in blue on my fiance's bike and can give you firsthand experience. The Clevis is narrow yes. I just removed material from the bushing they fit over (both the rubber and the metal collar) until they fit. I had to drill and tap the hole larger exactly as described. Other than that? These are damn fine shocks for what you pay. To hell with anyone who says they aren't. I have put many miles on these just to see how good they'd do and I am impressed. If you have any troubles with them, Chris Livengood sells a service where he takes your shocks, rebuilds them (some of these RFY's are improperly assembled from the factory) replaces the top out springs, and recharges them with nitrogen (another know issue is that these shocks come improperly charged). It could be argued that you could buy a more expensive set to begin with and avoid the rebuild but when you already have them, his service can remedy any issues you may have. I haven't felt the need to have mine done by him as they work fine.
