So, for now I made the seat "hard mounted" w/ no spring, but I'm thinking of making it a springer seat. What springs should I use? I was thinking of moving the crossmember down a little lower, welding some valve springs onto the crossmember, and then welding some tiny coil buckets onto the seat to keep it in place. I'm thinking I only need about an inch of travel. Will 2 valve springs bottom out w/ my weight too easily? (180 lbs)
