I´ve been on four strokes since the ´02 yamahas were released. With the release of the ´05 125 I am considering going back to two stroke (if the rumors are true)...Can anyone tell me if this bike really can compete with the yz250f? I have heard rumors of extreme increases in power; along with the weight savings I would assume this would be the definative two stroke answere to the YZF. Also, has anyone had a problem with the plastic impeller. Plastic leaves me with an uneasy feeling (are a few grams really worth the chances that it may break easier?). Any other problem areas anyone can inform me of. I hope this bike pans out to be the four strokes nightmare (the more choices we have the better, right?)!
