I recently changed the fork oil on my R80. I had the front forks disassembled for a while before I could get started on them again. When I first put them back together I realized that they were way too soft. They would collapse under my weight. I figured that I must have forgotten something but couldn’t figure out what. I cut two pieces of pvc pipe 1.5 inches and added them to the forks for increased spring stiffness. I also experimented with 1 inch pieces but felt the forks would collapse too much. Now the laden/unladen compression difference in inches is within limits but I feel every ripple in the road. Got any advice?
