Using the term Green stripe almost sounds like a marketing gimmick LOL like something someone says like balanced and blueprinted or something LOL..
That kind of stuff gets passed on from person to person and gets boosted about with no knowledge. Person that sold it to you should have been able to completely explain what green stripe means...
With all that said there was certain colors put on certain gears so the factory would know what goes together and what gear ratios they are. In all likelihood it's just a common gear ratio... Taking the side cover off gives you quite a good idea of what's going on. It's easy and informational...
