Keep the oil injection dude, if it ain't broke don't fix it. Like others have said, it is wonderfull if you plan on riding the bike anywhere serious. All you have to do is top the gas tank off at a fuel stop, check your oil level once in awhile, and ride on. Carrying a bottle of 2stroke oil and measuring untensil stinks. Leave premix for racebikes or vehicles like mopeds where you dont have to fuel up quite as often.
