Hi renos!
That is the exit hole of the crankcase breather. It has to stay open.

Renos,


That breather hole has caused much discussion about whether, or not, there needs to be a tube attached to it.  Tube would route any oil that makes it through the breather channels onto the primary chain or, if you prefer onto the ground. I think it is safe to say that most A10's do not have a tube installed. I might be corrected by more knowledge members here.

Oh, and a big welcome to the forum.

Renos,

I think it is safe to say that most A10's do not have a tube installed. I might be corrected by more knowledge members here.


Welcome from a less than knowledgeable owner; the previous thread on this topic got me thinking that I remember seeing one on my original engine (AA7 Plunger) but not on the rebuilt engine with BA10 crank cases and A7 iron top end.
 
Correct - no pipe on rebuilt engine, so dug the old cases out which DO have a pipe fitted - see pic below. Not sure whether this pipe is correct or not since someone (not me) has 'modified' them a long while back by cutting the top off the clutch back plate? The breather pipe looks like is been damaged by the chain at some point? May help?? *conf*


Now looking at fitting one retrospectively (wife has small hands ;))   
Regards

RR

It seems that the pipe was fitted to plunger engines but not swinging arm.
A good idea to retrofit.
