Which has better performance?

[akreider]

What would create the biggest increase in performance pods or velocity stacks (each with proper jetting)?

Velocity stacks come in different lengths depending on where you want to make the most power. K&N pods have built in velocity stacks. If you plan on riding this on the street go with the K&Ns for the sake of limiting engine wear.

What about the emgo filters I just read a thread that said that they can cause some problems in power delivery. Or would I be fine if I got them?

Emgos don't flow near as much air as K&Ns. You only get what you pay for.

Do you know anything about the pod filters that Star Racing sells, I didnt see the manufacturer.

If it's Star and they run about $125 they are more than likely K&N. Post a link.

At that price they aren't K&N, look to be Emgo. Did you notice they only fit RS flatslides?

[akreider]

Is there any other air filter pods that will give decent performance but cost less than the K&Ns?

[Billy Ricks]

Someone else will have to answer that. The Emgos are probably alright. I've had the same set of K&Ns now for about 19 or 20 years, well worth the cost.

Do the K&Ns require jettings. what would happen without jetting.

The individual K&Ns do require rejetting and you need a free flowing pipe to get the most out of them. Without rejetting the bike will run way too lean.

Another thing to consider. More often than not, you'll need a jet kit. The jet kits I've seen are designed to be used with K&N's filters and a QUALITY pipe.
If you run cheaper filters and/or a cheap or "home made" pipe, you'll most likely have problems jetting. You'll defeat the reason you bought the jet kit.
Besides not getting the kind of power you expected, you'll be wasting YOUR TIME and getting frustrated. Time is money. Also, if you jet the bike wrong, it will be rich or lean and both cause their own problems.
Jetting can still be a challenge, even with a kit. But they've always helped me.

Ditto for the K&N's. I've had both Emgo's and K&N pods, the K&N's are worth every penny. With the recharge kit you can make them brand new every time. Add you get the cool sticker!

I bought a used set of K&N's on eBay fro about 40 bucks IIRC. They were fine. Pretty much any old bike's pod filters that uses CV carbs will fit yours too.
