symjet 4 gy6 plumbing?

Hello all.. does anyone have any pictures or info to where all the hoses on a gy6 engine go? Just brought a recon engine.. fitted it and now im struggling to find where some hoses go.. unsure what thay are for.. i assume there some sort of air hose.. it runs around the front the engine to a overal shaped like giant t-peice thing.. if anyone has any pictures of there gy6 plumbing that would be great

Many thanks

 

i would say its the pair system ie the emmisons recovery system if its the 4t model motor

 

Hmm ok.. dont suppose you would know where it would likely attatch to? Do you think it is needed for the engine to run?

 

video shows them removing the system , so could give you a clearer picture to what it does and how its plumbed in.
nope not to run engine its for emissions it recycles them throught the airbox etc etc so bike farts a bit cleaner on air to keep up with emissions laws, kinda stupid for a low powered 50cc engine.
