when's the last time you checked the weight of a raptor? you must have read wrong because raptors are only 12 lbs. heavier than banshees. that's 2-stroke vs. 4-stroke, 350cc. vs. 660cc. you should be calling your shees pigs, lol.[img]i/expressions/face-icon-small-happy.gif[/img]

 

i have built them all. i would start with a full exhaust, (big gun, trinity, sparks or any big name they are all close) then a cam, porting, big bore, carbs. forget the prodesign setup unless you go through alot of mud and water dual k+n's with no airbox you give more airflow
