Hi all,
I have a 1985 honda spree.
We need a new fuel petcock but need to know what the size of the thread is on the tank.
Thanks a bunch in advance!

It's a good idea to measure your threads. After almost 40 years, previous owners may have swapped in a different tank.

OEM Spree petcock threads:
Honda Spree 1984/1985 (Small Thread).
14mm x 1.0mm pitch

Honda Spree 1986/1987
16mm x 1.5mm pitch.

Greetings:

This change in thread diameter was not limited to the Spree, either. When I bought my 1987 Aero from a friend, he had ordered a new petcock, but dag-nabbit, it wouldn't fit. It was for the 1985 Aero, which had the same 14mm nipple as Mouse describes for the Spree. I'm guessing the '87 Elite also used the 16mm version.
