Hey man, I made an account just to answer your question. I have a banshee and its my first quad. I love it so much. It is very very reliable. Ive been riding hard all season and compression is still high. Ive had no problems with it and i loveee it! Its awesome in the trails and amazing on the dunes... Mine has dual k&n air filters, fmf fatty with turbine core 2 silencers, renthal bars, dg alloy series nerf bars, dg fat v-pro bumper, itp holeshot tires, I think thats all... When you get one you wont regret it, Just make sure you dont get one thats been beat on. I do have to warn you though, Once you start buying things for it you'll never wanna stop.
They are okay on gas id say you can get 3 to 4 hours on it and they have a gigantic reserve tank so you should be all good, and they are kick start. Sign up on bansheehq.com Thats all it is is banshees and people on there will gladly help you out.
