Okay, there are so many different connections for the different hoses to go to and the manual is just confusing me!

I take it the main fuel hose goes to the bottom at the back in the middle.

What about the other hoses?!

And the vacuum hose goes to the little connection of the inlet of carb no. 1, right?

Also, when balancing the carbs, which screws do you turn? Is it the screws between each carbs on the throttle return springs?

Pictures may help guys

Thanks!

you are correct with the hoses, top hose on the carbs is an air vent for the bowls and just sits open ended.

I'm also wondering where the carb breather pipe goes. If it's open ended, where is the open end usually routed to?

Either straight out the bottom of the pipe or connected to the coolant breather with a y-piece then that has a hose connected hanging out of the bottom of the bike.
