better fuel petcock TBR7

[alex_in_az]

I can't shut off the fuel supply at the petcock. it's supposed to be off with the lever in the horizontal position, but it still has a slow dribble. Does anyone know what the design was copied from or is there a more quality replacement part available? the thread looks to be M16 or 5/8"

You need to replace it, i had the same issue, sometimes they fail and they keep sending fuel even if they are "closed".

Honda has a few petcocks that look the same, the 18x1 is the 16950-kpe-900 whcih is used for the XR 250, XL 250 and so on.

The Chinese CG use the petcock that was made for the nxr125 which is the 16950-krh-901 instead of M18x1 it is M17x1


But with the Chinese you never know... So if it is M17x1 it is the Honda part #16950-krh-901 but if it is M18x1 it is the #16950-kpe-900
