Powervalves? Now my waverunner has powervalves on it and i just recently found out about them being made by aftermarket companies for fourwheelers. I saw a set on a auction for 1200 dollars. Is that a good price? What kind of performance gains should be expected from putting them on a banshee? What companies are producing them?

The only two ways at this time that I know of that you can put powervalves on a shee is by finding an old RZ350 yamaha street bike and putting the jugs off the bike on your banshee. Since your banshee engine is basically this motor less the powervalves they bolt right on. You do however need to add a battery to your shee to run the powervalves as they are electric. Another way is the FMF power up package. This package simply bolts up and the powervalve is exhaust pressure actuated so there is no need for a battery. It also gives your shee a 400cc displacement ; ) I have heard there are others coming out with such kits also but have not seen them yet. Hope this helps.

I saw some sort of a power valve top end for a banshee on ebay today. I didn't notice if there was a brand on it but the whole thing was made from billet aluminum. at 1200 bucks it'll look really cool on someone elses quad.
