god damn boy what a lie that is . 2 strokes have power an lots ill give it to 4 for that 1 though . They surely dont have the same engine though . 4 stroke have valves that have to be adjusted . 2 strokes have no valves at all wierd rite . 2 strokes dont have enjectors and 4s do . So it would cost bout 1000 to completly rebuild a 4 stroke . And only cost like 200 ish for a 2 stroke . i dont see which is easier to maintain there the same exact things cept you gotta adjust valves on a 4 and not 2 . Now about speed a 2 stroke are legends 4 really arent at all . when a quad is built the first thing they put it up to is a twin banshee an most the time the banshee wins . Cept for some of the new 4s . You can really just pipe an banshee an it will usally take anything there is . Why are you guys such 2 stroke haters . maybe you guys are wimps an cant handle a power band [>:]
