Message: [QUOTE="scotth, post: 394270, member: 24906"] Try a different taper needle. I am using a ‘N3EJ’ needle in my 02 KX250. It removed the hit and created an extremely linear power band. It is excellent for trail riding, vary controllable. The only way the bike could get away from you is if you mistakenly twist the throttle wide open. The stock needle in the 02 (NAFF) is a triple taper and dumps an extra amount of fuel at about 1/4 and 5/8 throttle. This gives the bike a hit in the power band. The ‘N3EJ’ is a double taper needle and delivers the fuel more evenly over the entire range of throttle positions. Since I switched to this needle, I have also not fouled a plug. The needle is leaner then stock, so you will have to experiment with the pilot and the main. I am currently using a 55 pilot, 170 main, and the needle is in the third clip position. My bike also has an 11oz flywheel weight and an FMF Q Spark Arrestor. Good luck [/QUOTE]
