so i rebuilt my cb550 forks. im pretty sure my springs are totally clapped out. there is about 1.5" of sag when i unweight it and then let it drop. then when i sit on it another probably 3/4". i put a zip tie on the tube and it bottoms pretty easily under moderate braking. and i have noticed it sometimes crunches pretty hard in some of our nice city potholes. im running 145cc 10 weight. like the book says. how much of a difference are my new springs going to make??? anyone??? or will it still have that crappy mush feel?
If you want to stiffen the springs, cut them and replace the length with spacers (pvc). Cut an inch off at a time. Worst case, you go too far and have to buy new springs. Best case you solve your problem.
