I find that some new springs I purchase don't match their rating. I have also discovered as have others that old springs lose their rating over time or repatitions.
That said I made a fork spring tester so I know what the rating is before I install them or during a service.
I used some scrap ali I had sitting around.
First I cut out the base discs with a hole saw in a drill press.
