I have bought a kx250 1989 in spare parts(you know a need spareparts)
and I was surprise to find it have the same induction and scavening system as kx500
The same reedcage

and KIPS-system.
Almost the same porttimes and pre-ignition.
But most surprise, in pistonskirt a boosthole were drilled(tought I was the only one to drill that)

I will buy a camera and take some pic?s later.
Do anyone know the "forkangle" for the kx250 -89, for the kx500 is as you know 27 degrees?
