So you want shorter "gears" (Shift more often/quicker) and more torque/acceleration, right? Go UP in teeth on the REAR sprocket and not the front. I'd never change the front sprocket unless you're looking to make a drastic change, going down 1 tooth on the front is about the same as going up 3-4 teeth on the rear. Here's a neat little calculator that will give you all sorts of numbers.

James,
Take this information and make a thread in the tech info. When I first started riding and learning about gearing this would have come in handy.

yupp, idk why i was thinking up on the rear up on the front
Huh? 2 Strikes, going for the 3rd?
Don't we have a "FAIL" thread somewhere? 
I think what you're trying to say is "Up on the rear or down on the front, for shorter gears"?

for some reason when i was posting that i was thinking more teeth on the rear=more teeth on the CS sprocket no idea why either

When I first went to change my gearing I had a long argument...err...debate with a buddy on if I needed to go bigger or smaller on the rear. Turns out I was wrong 
, so now I don't forget which way it goes.
Bigger on the rear gives you more torque (@the wheel) and smaller gives you more top speed
opposite with the CS sprocket
I knew what I was talking about the first time then
So anyways, any suggestions? I have no idea what I'm currently running tooth-wise but I really want my gears a bit shorter
ok... lets try this again
Try going down 1 tooth on your CS sprocket, so if you have a 13, get a 12, if thats helps, but not enough go up a tooth or 2 on the rear sprocket, and you should be set!

And CS sprockets are also loads cheaper, and easier to replace...Not to mention mine is looking like it needs replacing some time because the teeth, while still sharp, are pretty warped

It sounds like it needs replacing now. The teeth of a new sprocket are not sharp. They get sharp as the sprocket wears. This is what it looks like when new:
Travace, I'm running Warp 9's on my bike with heavy duty Buchanan spokes. I'm really happy with this set up. I've taken some hard hits to the rear that I was sure would have left a flat spot on the rim. However, both rims are still running true.
I bought them from Rocky Mountain ATV for around 80.00 each. They weren't displayed on their online catalog so I e-mailed them asking if they could sell just the rims. They sent me a phone number to call and I ordered them by phone.

I thought it was just a design variation. Anyways, checked today whilst cleaning my filter, I'm running a 14t currently, so I guess I'll try a 13 when I can scrape up a few bucks.
