Anyone willing to share their experience setting the rear shock on a LS650 (Savage), S40 or S50? Detailed instructions would be appreciated. I have the Clymer book and it seems to leave some details out. For instance, do the shocks have to be decompressed and tricks for doing it if needed. Also, the notches for the setting are not visible. Are the changes made by feel only? All suggestions and help appreciated. Thanks!!!
