I've never really been too much of a "weelie master," but now that I've recently got the hang of ridin' "2nd gear weelies",(50-80mph) I have been addicted to 'em since! Call me greedy, but I want more...I've heard aftermarket sprockets do just that. I'm sure some of you guys have had this sudden need for speed, and have upgraded to bigger sprockets for a lil more "bite". I'm just curious how big of a diffrence you can feel, and any tips on Brands/Sizes, or any other info I might need before buying would be awesome.
