I haven't upgraded my VFR suspension yet, but for the record I put a new YSS shock on the back of my 07 SV650 two years ago and I've been loving it. I researched for weeks and found they were the best value for getting a brand new shock that's great for aggressive street riding, has a good range of adjustability, and is fully serviceable at the end of its life. For me, it beat out the prospect of going with some old, used shock from a different bike or trying to hunt down a Penske or Ohlins that would probably be overkill for what I'm doing anyway. I never even adjusted the shock after mounting it on my bike, it felt pretty good as is. They are made in Thailand so the English on their website is not the best, but the payment and delivery process was very professional and quick. Just throwin my two cents out there since I saw it being mentioned.

Race Tech sell the Schrader valve to recharge an OEM shock. Most common spring rates I’ve seen are over 1000#. My Penske has a 1300# spring and is perfect for my fluctuating 200-220 pounds. You’re going to need to alter the valving, if you’re planning to change the spring. Not sure anyone will be giving up shim stack info for a specific spring. If it were me, I’d buy a YSS and be done with it. However, the shock will highlight how bad the frontend is and you’ll be needing to rework that, as well.
