coolant pipes AGAIN

[PARSLEYRIPPER]

Sorry guys if this question has been asked before, I did do a search but cant seem to find a definitive answer. I am trying to put my bike back together after the engine went bang, unfortunately I have two coolant nipples I am unsure about. There is the smallest one on the waterpump housing the large one and medium one are no prob. And the smallest one on the thermostat housing, again the larger ones are no prob. Do these two small ones go to the carbs i.e. in and out for the carb heating? I seem to have two nipples/nubbins on the carbs that don't seem to have pipes off them ???? Sorry if this has been a long winded way of asking a simple question.

The smallest pump stub goes through both carbs- can't remember where it ends up, probably thermostat housing.

There's one blanked -off pipe outlet on the thermo housing- have a look and you'll see which one- it points backwards.
Nothing connects to that, of course.

Thanks very much, it confirms my suspicions, oh and I am assuming the top pipe off the expansion bottle vents to atmosphere. I have a bundle of small bore vent pipes tied together, I think one of them goes to the tank?
Thanks for your help, it feels like it is never going to end up back on the road

Correct the top pipe vents off and is bunched with other pipes near the oil filter. The bottom pipe off the reservoir connects to the nipple on the right rad filler cap.
