Last week I replaced my fork springs with some racetech (.40kg) ones. After I put the forks back in and got everything put back together, I noticed the stock springs had what looked like a washer, with tabs to hold it in, on one end of the spring. They are not the spacer guides and I did not see anything in the exploded views in the service manual. I have also checked the threads and did not seen anything on them. Do I need to pull my new springs and insert these washers? If so, do they go to the bottom or the top?
