Can anyone please tell me which was the first model YZ 125 to run non-metal reeds (I'm guessing about '83). I know the H is metal.
Thanks. :)

The K motor I had, had fibre reeds.
So the change over is J or K (never owned a J, so NFI what they have).
-
Ok. Thanks Nathan. I'll get a set of K.
-
For your H? Don't they still have the little reed block, and the K has the much larger one with six bolts?
-
Going off the search, it is four bolts as well. The 250 is six......

Ah, my brain is slowly getting back into gear now:
Yes, the Ks still had four bolts, but they are a much larger block than the earlier type. Seem to recall there being a difference in the shape too - maybe a curve on the top and bottom edges?
I can ramble all night about stuff I half remember...be worth checking the part number/diagram of reed block itself, and the gasket. If I'm right, the K reeds (and block) are way bigger.
