I drilled a hole on the lowest part of the airbox, and inserted a valve stem with a clear tube on it, then a bit more valve stem on the other end of the tube so I could put a valve cap on the open end.
If she get's upside down or floods the airbox, I can see, and easily drain.
Very nice job, lovely looking bike complete with period cow-horn bars... One of those was my first proper trials bike and I have one in the shed waiting to be rebuilt like that - one day...
