Yes, all of those bikes are running 22" tires. They are all direct copies of my bike. Me and my brother were the first to get into the 18DMs, back in 2010. Now everyone else has them, along with our setups from about two years ago. I am constantly changing our setups for the better and everyone else plays catch-up.
I've made it into KOTH every climb I have been to this year. My run at New Ulm, MN on Sunday was the 3rd fastest time of the day.
I usually don't stay for KOTH, but when I do, I am usually top 3. A couple years ago I won KOTH at Mankato. No ATV has ever done that in District 23. And I currently hold the ATV hill records on every hill except for Bay City, WI. I plan to set that one this weekend.
I must've missed the jetting specs and set up..
