I just bought a 2003 Prairie with 76 miles on it and 27" dirt devil tires. I have read a ton of post on this site about Prairies loosing power with 27" tires so I tried a couple of wheelies from a dead start. This thing is crazy! I don't even need to pin, I just juice the gas for a second and it stands right up, I was leaning forward too. I used to have a Suzuki quadracer 250 that was modded pretty good a few years ago, so this quad felt a little sluggish compaired to the QR, but the more I ride this thing the more pleased I am.

I was going to purchase a Dyna CDI so I would be certain to beat my buddies Artic Crap 650V2 and Polarbus 700 but I think this machine will do fine stock.
