Thats awsome. Hopefully this atv will get a lil recognition. By the way, disregard the jetting specs I stated earlier in this post. I found out that when I ride in warm weather the engine has a bad stumble from a stand still. I found out what it is after 4 days jetting and re-jetting. Word of advice to anyone, don't buy a dyno-jet jet kit for this bike. I called their tech support and the guy was rude and was not very helpful the first time I called and the second time I called the fellow didn't seem to know the answers to my questions. To top it off, I fixed the problem by removing their jet kit and using the stock needle with a 138 main jet. Fixed the stumble totally. Saturday I'm gonna head out to my friends property and finish tuning for the highest top speed. I'll have 1/2 of a mile straightaway. Hopefully I can get 60 mph out of it. The highest I got before the cam was 52 mph. Wish me luck. I think soon i'm gonna pull the head off and port it, and see if my machinist can shave a little off so i can get some compression...might now be much, but any will help. I have been considering putting a 400ex carb on it, but it might be a lil to big. Anyone have any other suggetions?

If any of you guys upgrade your stock carb to a larger one, would you guys sell me your old one? That's one of the differances between the Ozark and the Z250. The Ozark has a 25 mm carb while the Z250 has a 29 mm carb.
At the end of next week, I am going to have a pretty nice chunk of change burning a hole in my pocket. Thoughts of a cam keep running through my head. I also can't get the turbo idea out of my head either!!
