a 250r thats setup right can run high 4's in 300 feet and high 6's in 500 feet ,but your gonna lose a lot of lowend o n a dra gport and really sometimes an mx style port layout will get you for mpoint A- to point -B sooner ....the chassy suspension tires gearing etc. have just as much or more to do with it as the engine output does in the atv drag racing world |
