Hi, I just had my forks rebuilt on my '72 R75/5 by a shop in CT. I got the bike back and the front end had a loud tactile rebound knock - the forks were tight and not dangerous...I brought it back and they inspected it, put heavier fork oil and said that nothing is amiss and that's just the way it is with the stiffer Progressive springs. I had a 73 /5 back in the day with Progressive springs and it never knocked.
Has anyone ever had this experience with Progressive springs?
They said only way to remedy is to install a $200 valve (of some sort) or replace with stock BMW springs (and I'd have to pay for the 4 hrs labor and the materials)...any thoughts?
Are replacing springs beyond a competent home mechanic (I did my push rod seals no probs)?
thank you Chuck
