Me too. And the airbox boot...

Thanks for the photos to compare. The 250 manifold I have has the wings like the 500. I made a reed spacer with @ .050 taper to help move the carb away from the shock spring (pipe side thicker). I do not think it will affect the flow into the cylinder enough to notice.

Is this a good deal?
LundMx:
So an 88-93 kx250 manifold, a custom cut spacer and what airboot do you recommend to try first?
cmotodad:
After reading some posts on the KX250F builds, it looks like they are close to the shock too. I tried to taper the reed spacer to help carb to spring clearance. It was a no go, it pushed the carb further back into the spring. I am now try to heat the manifold while spacing it away from the spring. Right now I have @ 3/32' from the spring but would like more. I may end up making a manifold (like Boyseen).
