stroker cranks are the hot setup... im in the process of building my stroker... it will add a lot of bottom end, but you wil see big gains over the whole power band. PassionRE does really nice work so i hear, if you have a stock shee, and want this stroker banshee, youll need pipes, carbs, porting, clutch and many other things. if you get a shop to do it, look at $2000+ at least thats what mine is with those parts. of course me n my buddy are building it just shop costs for porting and mine is getting bored .040" over. good luck
