    yes, it wont idle, getting way to much gas or something. it seems ok, not fine but ok in 4th and 5th from about 1/2 to 3/4 throttle, but after that you dont gain much.

    Ok well your pilot jet is where you need to start, try goin down a size. If that helps but its not perfect at 1/4 throttle then go down one more. To help between 1/4 to 3/4 throttle you need to adjust the needle clip. If its rich move the clip up, if its lean then move it down. The wide open throttle is handled by the main jet. If you spit and sputter on wide open throttle then you need a larger main. I suggest doing some plug chops at different throttle locations to see where you need to make adjustments. A plug cop is just riding at one throttle position for 30 seconds then kill the motor and grab the clutch and stop. Make sure you do not close the throttle until the bike is shut off completely. Remove the plug and check to see if its black(rich), tan(perfect) or white(lean).
