Emissions hoses, Tao Tao ATM50-A1 By dahermit (Read 439 times)

Just bought an non-running 2014 ATM50-A1.  

I am in the process of attempting to get it running... pervious owner(s) only put 1114 miles on it, so I am hopeful it is not majorly screwed up.

My fist novice question is: There are two large hoses hanging down from the emissions system (I assume) on the Right side of the engine, the do not go anywhere... just hanging.  Reading the forums, it seems one of them (the one with the "enlargement" (like a big inline fuel filter) on it is supposed to hang down to vent to the atmosphere.  Is that correct?  As for the other, I cannot find where it is supposed to attach... would someone please clue me in.  Please do not tell me something like: "It connects to the valve cover..."  I have no idea what the component parts are, but would find it helpful if you direct me by using Right side, Left side, to the front, to the rear, under the engine, etc.

Go on the web for GY6 50cc service manuals. Also YouTube. The best I can tell you is to look for open attachment for the hose. If you could post pictures of the hoses that would help.

The service manual is useless in regard to the routing of those vacuum hoses... does not address them at all.

Nevertheless, I have taken a picture. The picture shows that there are hose clamps on both hoses. Therefore, I am assuming that neither vent to the atmosphere, but are supposed to attach to something.


Here is the source of those hanging hoses:  

I found where perhaps (size of the connection is about right) one of the hoses is supposed to attach... on the very front of the engine, close to the bottom.  But I don't know which hose goes there.

Addendum:
Those hoses (1/2" I.D.) seem to be related to EGA system. I think I found where the longer (24") hose goes. There is a 1/2" hose connector on the front of the Cylinder Head Valve Cover. The shorter hose with the inline thing is not long enough to get to that fitting.
Here is a picture of where (Red Arrow on picture) I think that hose attaches.

That is DEFINITELY part of the "exhaust emissions" system. I wish I could help you hook them back up, but honestly that system is the FIRST thing I remove after acquiring a scooter. Unless you happen to live in California (or some other state that requires emissions tests for scooters), that system will end up causing more headaches than you can imagine . . . everything from vacuum leaks to full canisters of crap that keep your scooter from running (not to mention the costs of replacing those cute little containers)! IMHO

I have no interest in removing the EGR system or hoses. It may not be illegal to do so in Michigan (my home state), but it strikes me as environmentally irresponsible. It seems that most people remove such to obtain a few more miles per hour, which is questionable for a 49-50 cc moped unless you are restricted to mopeds due to being too young to qualify for a license to drive anything bigger.
