Zzr motorbike carbs help
 

Hi all wondered if anyone could help can anyone identify the connection on my carbs they are zzr 600 carbs

I assume plastic tube at the top is a breather, centre pipe at bottom is fuel in, smaller pipes linking all four carbs exiting at each end is overflows?

Many thanks in advance

top pipe breather
single pipe fuel

the linked pipes at the bottom are for warm water from waterpump in out to remote filler or header tank
it keeps the carbs warm to stop carb icing you wont beleive how cold they get im building a zzr1100 just for track days and im leaving them off but for road work i would leave them conected

Thanks for the info much appreciated
