jd jet kit

Recommended Posts

i have a 2010 kx250f that i just bought a jd jet kit for. after i installed it i went to ride today, and my bike runs like complete crap. in the slower sweeping corner the throttle is like jumping and dying and jumping and dying, and off the face of like a 4th gear pinned jump the bike will bog right up the face. im at 500 ft above sea level, it like 60 degrees. i have a 185 main, a 45 pilot, and the red needle 5 clips down. any suggestions?

That setup sounds rich to me. I think the 2010 came with a 182 main? Is the bike stock (displacement, exhaust, etc)?

The 250f Kawi's are typically rich in stock trim. Check the jetting specs from PC.
