I still need to get a new piston - but in the meantime the cylinder got scrubbed and degreased and the clutch cover got scrubbed and painted with VHT aluminium

So i have a +1 piston, rings, etc all ready to go. The cylinder has been rebored to suit.




However i noticed my power valve setup is a bit screwy. It appears like the centre valve of one of the sides has the wrong curve/shape...



it is not just simply a case of the PO swapping out the LHS for the RHS - as the outer radius is correct - its just the curve of the mouth that is backwards. Weird. It cant be that big of a deal, the bike was running previously. It is impossible to find these parts. I have a spare set but as you can guess, the required centre-valve with the floating pin is absolutely munched.





One side has a roll pin installed hard, the other seems to want one that floats? I have the "floating" roll pin here, ill have to work out how it is supposed to be seated in there without getting loose and killing the cyclinder.








Slow progress and finicky.

However, I also found a pretty good match with an 1993 RMX250 headlight

So a mate of mine tells me that the valve piece was likely flogged out and so needs to be completely filled with tig weld and then a new hole drilled. Seems OK to me.
