Have you made any clicker adjustments with your stock stuff? I'm wondering if you may need to simply back off your shock's rebound a little if you feel like you're gonna break loose on corner exit? I'd get into PK's shop and see what can be done with your stock stuff before dumping the cash. Is your sag set correctly? are your forks the proper height in the clamps for the tires you're running? That's the stuff I'd look into. Also, switching to a well-setup SV will make you a better rider and put a bigger smile on your face!
Brad i brought mine to Pete Cate's for a sag adjustment and gained a second not sure if you have done this yet but it helped me out.
I don't think that is bad advice at all. Budget wise, I would probably be able to do a little more in the lightweight class. However...I've just reached the point in MW where i'm competitve with a lot of my friends and it's setting up to be a pretty epic season in AM... I don't think I can walk away from that now! I would be more likely to add a LW bike to the lineup.
Yeah, I agree with you, most of my MX friends dump all of thier money into the forks. I've always run my dirtbike with bone stock suspension as well. I think i'll end up going this route and revalving/refreshing both ends.
Yeah i've done a number of adjustments to the suspension without much success although i'm by no means an expert and most of what I am doing is trial and error. Sag is set, but not exactly sure how great my geometry is. As stated before, I can't walk away from MW before this season starts!
Yeah haven't brought it to Peter, but i've set the sag. I might take it to him to set the geometry, but I imagine any trip to him won't be cheap.

Based on your feedback, It looks like you're to the point where you could benefit from some aftermarket suspension components. I say go for that Penske!
I guess what I'm really wondering is whether a Penske or ohlins is that much better than an OEM with revalving?

IMO - There are only a couple of items that make an after market shock "better" than a stock one. The first is that it may have more adjustments - high/low speed compression damping, ride height, or even rebound (if the stock shock does not have it). Then there is piston design - stock shocks usually have a very compromised piston port design, engineered to serve most riders, most of the time. Aftermarket shock pistons may have much larger compression ports, so that they can be valved much "tighter", but still blow off quickly. Lastly, they may have coatings that are much slippery-er, and last longer, and do not contaminate the oil so quickly.
The size of the piston ports will limit performance gains that can be had with a stock shock re-valve. Race-tech Gold valves address this, without springing for a whole new shock. Shocks like Ohlins and Works do not use the "deflective disk" design (which are basically a stack of thin flexible washers), but have their own (spring/ball, or spring/washer) proprietary designs.

A Penske will also have resale value, should your plans change in the future. A reworked stock shock is much tougher to sell.
A Pensky in the rear, some gold valves up front and go have some fun. If you really get ambitions get the geometry set up from PK. I was a little skeptical doing the geometry at first, then I dropped 2 seconds the day after he set my suspension up & I *thought* I went slower as I was working a lot less to get around the track for practice.
Just my penny worth of info... Good Luck!

Anyone have any experience with a Racetech G3-S shock? I can get one pretty cheap.

Every bike is different, but most riders would benefit first from having forks that work properly. You can deal with the stock rear shock by simply being smooth with the throttle and unweighting the seat over transitions. The forks, they create more problems in more areas and can cause the entire entrance and mid corner to be a mess.....at which point the rear shock becomes much less of a concern. Get the entrance and mid corner right first, then you can shift your focus to the back and and have it provide you with some real benefit. A mint rear shock paired with an out of control front fork isn't going to help you out a whole lot.
...just my opinion.

I ran 16s on stock cartridges...just got it sprung for my weight and never had any issues. I really think go for the shock first.
