Hey, does anyone know where I can find some websites about Big Bore Kits for my Banshee, All I found was Vito's 404 Banshee Kit, is there any other kits that can make your displacement bigger than that? I need mostly bottom to mid power mostly for woods. And I heard those FMF SST Pipes and Silencers Kick ***, any word on em?

 

Go with the powervalved FMF cylinders. 400cc, 2000$, but worth everything (in my opinion). If I had to change my cylinders, I'd call FMF.

 

There are tons of big bore kits out there from 380 to 500's Call the major engine builders and ask what they have to offer. I would be very skeptical of the FMF power valve cylinders its taken a few years to get the power valve cylinders worked out for the R motors so I would give it time before making that investment. There are alot of flaws with aftermarket cylinders in the port layout area.

 

Trinity. A friend has a 420 stageIII with a Paul Turner pipe and this is the fastest quad I've ever ridden. Trinity claimed 73 hp from this motor. I'm sure there are alot of other big bore kits out there but I'm telling you first hand that this Banshee pulls very hard.

 

CT has Pro-X cylinders comming out for the banshee in 420 and 450 bores. They havent given any prices yet.
