I have my Banshee Ported by Race Logic and going to put a New top end in it should I use the Power Pistons or Super stock?

 

None of the above! Use wiesco, pro x or genuine yamaha.

Any one else have any Opinions on Pistons for Ported Banshee Motors?

 

superstocks are not to be used with ported motors. they change the exhaust port timing for better performance on a stock ported motor and would not work well with a ported motor. that leaves you with power pistons. they'll raise the compression some (15-20psi more than regular pistons) which will give you much better low to midrange horsepower. i will also help on the top some.
