  1. A 2-stoke on trails....? Not a trail bike my friend. Great bike for track use though!
  2. Honda CRF 250.
  3. For those who care, I ride in Michigan, 250-1000 ft above sea level. I removed the exhaust baffle, intake "snorkel", installed a 120 main jet, a 45 pilot, left the stock needle in stock position (3rd from top), and am at 2.25 turns out on the fuel screw. WOW, all I have to say. Thanks for the advice on this thread everyone. Great advice to not tune on the stand in the garage lol. Took it out today and after warm up turned fuel screw out from 1.75 to 2.25 and all hesitation was gone. Wheelies in second, lots of power through every gear! It was 65 here today. Super happy!
  4. This is my first 4-stroke bike, trying to figure out how things work lol. Lots of things different from my old rm250 I had years ago.
  5. Great, learning things everyday. Thank, will report back with results after riding today
  6. Thanks guy's I will try to drop the clip to 4 and see what happens. I am going riding tomorrow so I will get a feel of real world conditions too
  7. Absolutely, Michigan west side, 500 feet above sea level and currently 60-70 degrees.
  8. Just picked up a 2003 crf230. Replaced the main jet with a 120, pilot jet with a 45. Left the stock needle in and at the stock setting (3rd position from top), 1 3/4 turn out on the fuel screw. I removed exhaust baffle and removed the "snorkel" from the air box. Starts right up with no choke and idles like a champ. If I slowly give it gas I have nice throttle response. Problem I am having is when is crank the throttle from idle it bogs and wants to die until I return the throttle back to home? Do I have the fuel screw turned to far out or should I turn it in more? For my elevation I matched my jetting to someone close to me, they recommended 1.5 -2 turns out on the fuel screw. I did not change the needle to the fourth position. Can you guys help me out? Carb is built correctly. Not sure if this is a fuel screw or needle issue? Like I said it runs great until I try to crank it from idle. Every where else in the range is great! First bike and not sure what to do.....thanks guys.
