williamjernigan Posted December 23, 2004 Report Posted December 23, 2004 Just curious what the difference is. Quote
Ryda85 Posted December 23, 2004 Report Posted December 23, 2004 the stroker cranks allow the piston to travel longer in the stroke, for example a +4 stroker crank increases the stroke by 4 mm.......also the aftermarket cranks come trued and welded. Quote

Is this related to stroker motors or long rod motors? Quote
Wallrat Posted December 23, 2004 Report Posted December 23, 2004 The pin for the blaster pistons is further up inside of the piston. Quote

Is this related to stroker motors or long rod motors? 296932[/snapback] The blaster piston has the wrist pin 5mm higher up in the piston which puts the piston in the same position as stock with a 5mm long rod. Wiseco made banshee specific 795 series pistons to do the same thing. The stroker plate, or cutom cut stroker domes are to make up the difference in the height of the stroke with the use of a stroker crank. On my bike with a 4mm stroker crank and no spacer plate at the bottom of the cylinders, the pistons come 2mm above the top of the cylinders and into the custom cut stroker domes. Quote

bansheefreak Posted December 24, 2004 Report Posted December 24, 2004 also blaster pistons stock size is 80 over on a bansheee.... this is why ppl have 370 lr cus they can use stock blaster pistons.... Quote
D34 Posted December 24, 2004 Report Posted December 24, 2004 Just curious what the difference is. 296912[/snapback] about 10% hp gain with the same port timing Quote
