Replacement 200X front brake master cyl reservoir ("oil cup")

[TurboVan]

Anyone making a billet replacement?
Or should I just use one from a Honda dirt bike?
If so, which one?
TIA

just put a new master on it. I have used anything from YZ85 to TRX700xx... everything bolts on. I ran alot of YZ85's on m 200xs so i could run ASV levers
