I have a 2014 which I bought preowned. The PO was thoughtful enough to change out the front suspension with .90 springs and 2.5 fork oil. I can't comment on whether the valves were done or if they were, which upgrade was used. I don't know which brand oil was used either. The rear shock was changed to a Penske 8393 double clicker which originally had a 600lbs spring. I weigh 185 without gear so figure 195 ready to ride. The stock tires are on the bike which has 1500 miles. I've done suspensions on all my bikes so this isn't new to me. What is new is I just can't get this bike dialed in to my liking. The suspension which at stock was way too soft (I never rode one so I can't comment) is now way too stiff. I've changed the rear spring to a 550, went to full soft and reduced any preload to 0. Still, no good. The bike does not turn in quickly and I can feel every pebble on the road. I have tried tire pressure from 32-36 front and rear and it hasn't changed the overall ride of the bike. I've read some others have had similar issues while the majority who have done similar set ups are very happy. I was thinking of going to 7.5 or 10 fork oil to hopefully make the front end more compliant. Barring that, a new front suspension is not in my budget for this bike. I love the engine and everything else about the FZ09 but I'm afraid I might have to sell her and move on to something more to my riding preferences. Any suggestions are welcome, I'm sort of at my wits end.
