Anyone heard of Ketchum ATV's. I found this web site, and oh, by the way, they claim a stock Trailblazer puts out 13.9 HP. I find that easier to believe than 22. I have rode a stock one, and if my Trailboss has 13.1, than a Trailblazer is more like 14. Go to this link and check out the comparison chart.
