I am runnin an o-ring chain. I hav a 2003 KDX 200, and I am on my 2nd chain. I have had the bike about 3/4 a year, and I did NOT change my sprockets through the first chain, because they had absolutelty NO wear. this time, weather or not they DO have wear, they are getting changed with some steel sunstars... or somehting along that line. By the way, i DO have that speed program that someone updated. Im really interested in seeng this sprocket one. Thanks for the help guys!
P.S. I have tons of leftover stock parts that I have taken off my bike, to try to make it look MX. E mail me if u need something. Ill sell it cheap, just to get rid of it. my e-mail is XR100Man18@HotMail.com
