I have a Tao tao atm 150 evo,,there is a breather line coming off the rear off the cvt cover that goes to a T where one end goes to the airbox and the other to a charcoal canister.Also a big breather coming from the valve cover to the canister,,and a small vac line from the intake manifold to the canister also,,my question is can I get rid of the vent line coming from the rear end,,plug it at its source,,and also plug the vac line at the manifold and just put a breather filter on the end of the big hose coming from the valve cover?
Would like to get rid of the spaghetti mess and simplify things for less future problems.
I will take some pics tomorrow if you guys need them.
Thanks in advance!!
regards
Tom

The hose coming from the rear of the CVT is most likely the VENT HOSE from your tranny. That you can just tie it up out of the way. The one coming from your VALVE cover if the hose is coming from the top of the valve cover that is your VALVE COVER VENT and that hose you can put a fuel filter on the end and zip tie it higher than the valve cover so if it squirts oil out it will drain back and not squirt oil over your motor.
IF that big hose coming from the VALVE COVER is attached to a VALVE at the front bottom and has a U shaped chrome pipe that is a PAIR system and you can also take that off BUT you will have to put a plate where it attachs to the head to cover the hole. All that does is suck in fresh air and there should be a big hose just hanging from the canister.

Thanks a million Alley!! I just want to minimize the vaccume lines,,if the pair is there to suck freash air,,will it still do so if I remove the big hose from the canister and zip tie it high,,it looks like a bear to remove? I would like to take the charcoal canister completely out also. Also I included a few pics of the canister one big hose looks like a vent it goes to a smaller canister then a hose from that just goes to nowhere(vent).The other big hose is from the PEAR,and the small hose goes to the opposite side of the intake as the fuel pump hose(vaccume line).

[replyingto=jerseyboy]jerseyboy[/replyingto]Here is what I can see of my PEAR system,the rubber big hose at the bottom goes to the canister I'm holding,maybe I can just leave that hose zipped high and put some sort of breather on the end of it,or just plug it all together? Thanks again alley! Tom Attachments:

Aren't you talking about two different systems?
One is connected to the engine. The U-shaped thing in the picture above.
The other is connected to the gas tank, to filter out evaporated gas.
I had a scooter with all this stuff on it.
My advise...
Leave the one hooked the engine alone.
I don't remember it being hooked to the vacuum system, but maybe.
But the other picture looks like the canister connected to filter gas fumes.
If you don't live in a state that requires that, just yank all of that stuff out.
Just leave the vent tube for the gas tank.
You can put a fuel filter on it to keep dirt and bugs from going up in it if you like.
Mine had a little petcock type valve that I left on it for that purpose.

Remove the two bolts that attach the metal tube to the PAIR port on the engine. Rip everything off that is routed to the PAIR system. You will need to block off the line that was attached to the intake/airbox. You will also need to fashion a metal plate and then use the two original bolts to block off the PAIR port.
Rip off the charcoal canister attached to the gas tank vent line, get rid of any lines or hoses or secondary canisters attached. Sometimes these systems will have a vacuum line attached, it will have to be blocked off at the source. Make sure to leave some length to the gas tank vent line and reroute it to hang down out of the way.
Ultimately you want to be left with only the basic components.
fuel line from tank to fuel pump
vacuum line from intake manifold to fuel pump
fuel line from fuel pump to carb
also
carb vent tube
float bowl drain tube
fuel tank vent line
There should be a fuel filter on the fuel line from the tank. Some scooters/motorcycles have a vented gas cap and no fuel tank vent line.

So just a flat plate cut to fit over the hole for the PAIR with two holes drilled in it will work,,good to know.

[replyingto=jerseyboy]jerseyboy[/replyingto]There should only be one PAIR port on the cylinder head. More than likely the other bolts are holding a bracket used to attach part of the system.

Here you go: After you take everything off you plug up the VACUUM LINE AT IT'S ORIGN by the intake manifold connector. The plate to plug up the hole in the head you can make one up or order one. Alleyoop    |
