Get a motion pro shock spanner punch. Get a friend to help set sag. Makes a huge difference. Then write down your settings and make incremental changes.
You could likely benefit from a respring, but if it is comfortable for you now and the bike performs well I don't know that it would be a priority for me. There is likely some room for improvement though as was stated before for some of the smaller or heavier guys out there.

That racetec website posted earlier was actually pretty neat to be able to get a recommended spring rate for, check that out and see what it comes up with for you. Mine were a little different that stock (not by too much) and I am 155 without gear which is right near factory set-up weight.
So I'm a heavy guy (135kg/300 pounds) should I be concerned re stock suspension settings?
The stock spring rates are a bit soft. For someone at your weight, if you're doing any serious track riding or spirited street riding then you might consider changing springs at least.
Springs and gold valves plus labor would be around $600. and that price is based on you bringing the forks if you would like to bring the whole bike there would be an additional charge for removal and installation estimated at $75. BUT!! Something seems wrong with the pricing of the gold valve kit, on their website they have the price of $399. which doesn't make sense as that price usually reflects a 4 valve kit, 2 for compression and 2 for rebound. The 1050 uses compression in one leg and rebound in the other which should mean only two valves. A two valve kit is $179. I will need to speak to someone aat Race Tech as this may be a misprint which would result in a lower price.
No insult intended toward Reactive Suspension, but I suggest you call Traxxion Dynamics (http://www.traxxion.com/) for another opinion. They have a truly superb reputation among the track day/racing community. I know they deal in Penske shocks but they may be able to confirm/deny some of the information you already have. Or, call Markbilt Racing since they are close by - they too have a superb reputation.

I already contacted Markbilt Racing. I just thought I'd show you guys what they wrote back. I wouldn't trust them with my speedie.
