Hi Dutchie
hope all is good with your little girl ,will post a pic of my liitle girl on her pw50 (now a 21yr old ) havnt got a scooby what the bits on the carb are or how the burn pattern on the piston formed , havnt been able to replicate it since ,trouble is with poor old jan deceased dont know who would know ,or what the material is on the clutch cover,kips covers and the water pump im guesing magnesium??
a tester for kx riders forum .piston burn pattern .carb bits .material of covers any ideas guys????
DoldGuy:
Royce,
My guess on the carb setup is a powerjet circuit, clutch cover setup Magnesium, pattern on the piston showing transfers are balanced (noticed it had a window mod too), gear position sensor on crankcase to alter timing, which leads me to the question about the flywheel on there (need some pics posted up :-D) also what type of ignition setup (CDI, Coil, Stator) as it surely has to be Factory Kawi to work with the Gear Sensor. It appears that you truly have the "Real Deal" that only very priviledged eyes have seen. Definetly want to see more pics of this motor & more info on the cylinder, head, pipe etc..
Thanks for Sharing!

That looks like a 250 motor. The gear selector looks like for a road bike motor. The flywheel looks like a 250 flywheel too. The burn patterns looks alittle on the fat side put does look good.
