Ok I took my Banshee all apart to powder coat the frame and when I got the engine out of the frame I took it to my Banshee shop and had them look at it. Well the engine needed new cylinders so I got brand new 2005 ones. My old ones were ported and the new ones are not. I did not have the money to port the new ones, so they got the engine in like new condition. I put the engine back in the frame, put my Toomey T-5
