Title: pipe for an AF swap
Post by: jrkawiracer on February 02, 2011, 03:18:45 PM
im building an aluminum framed kx 250, my ?? is what year pipe fits in the 04 kx 250 motor, im wondering if i can get a pipe of a 05-07 bike because i have to make mounts anyway. the motor im using a 04 motor

According to Kawasaki and Pro Circuit only 04 works with 04.
However, I have never tried to put any other pipes on one so I don't know what the real differences are.
Anyone else ever tried?

no you cant as the 04 and 03 kx 250 pipe slides into the cylinder where as the 05-07 slip over the cylinder flange

The 03 and 04 pipes will work on either bike. The difference between the 2 is that they changed the mounts on the pipe. The 04 has a mount on the top right side of the pipe where as the 03 has the mount by the stinger end of the pipe. Since you are putting it in a af frame and have to fab up mounts, it really wouldnt make a difference what year pipe you use. 05-07 is the slip over flange. Silencers are interchangeable from 03-07 also.
