Talk to Lee. He did my suspension on the 450 and will do my stretch on the 990 this winter. He knows his stuff and worked magic on my 450. I absolutely love it now and hated how stiff Pro-Action had it. Like night and day really.
Suspension is very rider opinion dependant.
Everybody likes something different. Often what some people think is firm/harsh works better for faster riders, where the soft suspension holds back faster riders, etc.
Pro Action did my dirt bike, and although I've adjusted it A LOT from where it was handed over, I have found a sweet spot where it's firm and responsive, yet absorbs what it should. It's reactive without being harsh, playful without being a worn out couch. I just have some fine tuning with shock preload as it likes to wheelie too much in hill climbs and out of corners when sitting.
On my XRR, I did the work myself but being that I use it for dual sporting mostly, it's set-up softer. It rails rock sections and river rock amazingly well, but it falls off with missing responsiveness and slower reactions. I wanted it to absorb washboard and potholes without losing fillings.
Everything has a purpose. I'd ask WHAT you want, and then see what the modifier provides, or willing to provide. What some say is great, others find issues.
What I do believe is lighter fluid is better. It changes viscosity less with temperature. Plenty of people wouldn't notice this. I feel it a lot on my dirt bike, but much, much less on my XRR, which runs 2.5w oil.
Look at viscosity charts and you'll see that thicker oil all tapers off much, much closer to the thinner oil's original and final ratings.
