    Front Fork Springs

    Hello again all, I’ve finally got my 1979 gs850g properly running thanks to you guys and it’s a blast. But as previous pictures of my bike show, I have little over an inch of fork travel and it’s definitely fear inducing and time to fix that. Due to the air valves being broken and not being able to source any i’d like to cap them and switch to progressive springs and go airless. I’ve searched the forums for hours and got some great info but I’m struggling to find a set of springs that I can be sure will fit my forks. I’m not too worried about the spring rates and such as literally anything will be better than my current situation, but any help determining what will fit (preferably from a reputable supplier and with quick shipping) would be a great help for myself and my safety. Thanks again and sorry if I didn’t find this posted elsewhere.

      Just from the picture, if you lower the fork tubes in the clamps you may gain a few in. of travel. I don't remember seeing any this far up.

        You definitely need to raise the front end, right now the sliders are slaming into the lower triples every time you brake hard or go over a big bump. Very bad.

        Straight rate springs will be better than progressively wound ones. Sonic Springs as mentioned (I'm the former owner) or Race-Tech can fix you up. If you want help selecting a rate let me know.

          Will I be alright going airless with straight rate springs? And I wouldn’t mind assistance selecting a rate if you have time, the bikes main use is backroads and I ride at around 170lbs.

            If you use the correct straight rate springs and oil, you won't need any air pressure.

              That’s a relief, I’ll do some more homework on spring rates and such in the meantime, thanks.

                I'll venture 1.0 or 1.1 with straight rate springs. I went with .9 a few years back, but didn't account for weight gain (mine).

                  Probably 1.0s, but it depends a bit on your weight and the kind of riding you do.
