    straight spring replacement

    Hello, I'll delete this after, but i cant find a good sticky on straight or progressive spring replacement. Yes I've used the search and can't find anything decent. Looking to use straight springs. Just need a little help.

    Looking specifically as to what springs to get and the spacer info.

    sorry and thank you.

    I use Race Tech straight .9, though I probably should have gone with 1.0. I recall a member here has a company called Sonic, no bad reviews.

    Most brands have a chart on their sites that will help you figure out which rate of spring to buy.

    2016 XL883L sigpic Two-tone blue and white. Almost 42 hp! Status: destroyed, now owned by the insurance company. The hole in my memory starts an hour before the accident and ends 24 hours after.

      you want straight rate springs. Either Sonic Springs or Race-Tech will have what you need.
      I used to own Sonic, so I’m a little partial to them.



      If you need any other info just ask.

        sounds good, i did some more searching and found sonic, so you just install the new springs with pvc spacers? how do you know how much to trim them to?

          The springs will come with instructions that detail how to do that.



          Give those read and let me know if you have questions.

            awesome, that article along with the others on their page clears it up. thanks so much.
            So I will be doing fork seals and the new springs at the same time, is there any weird difference because I'm doing them simultaneously?

              I was under the impression that simultaneously was the only proper way.

                There is a substantial amount of effort to do any one of those tasks.
                That same effort needs to be repeated to do any of the others.
                Why not do all the effort ONCE?

                  Best to do them together, less total work. Seals first, and then the springs and oil as it's all going back together.

                  A tip: Fork seals generally leak because of small nicks and dings in the fork tube. Those have sharp edges that tear up the sealing lip of the fork seals. If you don't address that the new seals will leak in short order. So, get some extra fine steel wool and lightly buff the tubes. Obviously most of the nicks will be on the front of the tubes, so concentrate there, but check all the way around in case the tubes have been off the bike at some point. Light buffing is the key, you don't want to go through the chrome. You don't need to get rid of the nicks completely, just knock the sharp edges off of them.

                    I'm getting ready to do this on my 1100e. I have new seals, retaining rings, dust covers and Sonic springs. Does the forks have to be completely disassembled for this task? Also my uppers have a hole in them that I am not clear what for...I thought mabey anti dive but not sure and my Clymers has no mention of it. Because of these holes in each would you install the forks into the triples, insert the set screws into those two holes THEN add fork oil and bottom them up while on the bike.
                    Quite honestly I have only rebuilt 2 sets of forks both on dirt bikes as I have always farmed that task out. I want to do these myself...cant be too awful bad I wouldn't think.

                      The small holes in your upper tubes are likely an air equalization port. Did you notice a couple of o-rings on the triples and a tube running between them?

                      That hole will be covered and sealed when you put the forks back in. With the Sonic springs you will not need to add any air, so no worries about the hole, since it will be covered.
