Had a great time riding my recently purchased 87 tw around the backroads (dirt and asphalt, no off road) last week,.....until I woke the next morning with a SUPER-SORE lower back.
Going back and sitting on the bike I noticed that I can compress the rear suspension about an inch with little effort and then there is a sudden "hit" or stop in the compression....from here I have to really bounce down with all of my weight to compress any further, which it does, but it feels very "boingy". I don't have any other tw's around to compare to, but it seems like it's all just spring. Time for a replacement rear shock I assume?
