Recently I have noticed vibration in my spider f3s it was not there before but now present - tension has been reset and belt aligned and doesn't seem any different check all mounts in great shape and tight nothing loose - the only thing I have noticed different is my elka stage 2 rear shock with remote hyd adjustment seems soft - when I first put it on last august and until a 2 weeks ago it was very stiff couldn't even make the back seat go down barely now I noticed that I can push it down and easily and it make kind of a farting noise on compression- when increasing preload before with the adjuster was hard to turn but now very easy - so I figure maybe a seal blew or something need to get it rebuilt - basically want your guys opinion that if this shock is not functioning properly could it cause vibration on the bike ~ ps tomorrow I'm gonna try putting the original shock back in and see if different ?
