Re: Sprocket Swap
The 'standard' is one down in front, and 2 up in rear. This should net about a 10% change in effective gearing. You can go down MORE than 1 in front, or add more than 2 in the back, but rather soon, you'll find your fuel economy severely limited.
Changing the sprockets messes with the speedo, so be warned before you start.

I find it easier to change out the rear as opposed to the front. I have several different combo's that I use depending on either the track I'm at or what exactly I'm lookin for in street riding.

I can't wait to modify the sprocket on mine. My bike has about 9k miles on it and it is sort of at a place where if I want to change a sprocket, I should really change the whole thing, and I don't want to do that.
I am waiting until I hit about 15-16k before I change everything. (is that too high, btw?)
I think going up a couple of teeth on the rear should be a good modification from stock. as it is now, the bike is falling sleep at highway speeds, so I am thinking why not use the extra torque at the bottom end.

Ideally, you should change out the front & rear sprocket along with the chain at the same time. They all tend to "wear" the same and at the same rate. If it looks like the rear needs to be replaced, the front probably does as well.
Once the teeth start to get pointy...its time.

Re: Sprocket Swap
Thanks for the info. I understand the fuel mileage and speedometer inaccuracy, and I can accept those 
I just find it unneccessary to have all that top end speed, when I rarely even get to break the ton around here. I want to bring some of that power down into my usable range.
