After talking to the nice gentleman at sonic springs today, I've decided to order a set of the 1.2 springs, cut the spacers to 125mm, use 7.5 wt. oil per his recommendation at 125mm down the tube, and see if that helps my sagging front end. I tried the nylon tie check tonight...It sags over an inch just sitting on it, and moved the tie 4 inches just coming to a gentle stop in the driveway.
I'm also thinking about ordering a complete rebuild kit for each fork leg and replace all the bushings and seals etc.
For some reason, I'm getting a clanking sound when I push down on the forks, that can be both heard and felt through the grips, and its not the steering head bearings.
Will update this thread after my install when the parts arrive.
