My '68' T120 seems to have a bit too much fork sag. I measured the springs when I had the forks apart and they were in spec length wise. I have no way of measuring the rate. I'm getting over two inches of sag from static (frontwheel off the ground) to weighted (me sitting on the bike). I weigh around 140 lbs. Does that sound to be in the normal range for these oldsters or is it a bit too much. I feel like I'm riding down hill and would like to raise it up a bit.
