i dunno how a 4 stroke can get ported.. but... last year i could stay with them. just have to out ride them. only place were i couldn't take the 4 strokes was on a long straight away. two fiddy just didn't have the oomph. but that was almost compleatly stock. we'll see how she goes, i still have the 250 motor so. i can always put that in and run the 250 class |
