I don't have enough posts to have permission to make a wiki, so I'm posting this here. If you want, you may move this into a wiki.

Here is how I removed my EVAP system. It was easy, and took about 30 minutes. I now run much happier, and don't have to worry about vapor-lock, or flooding my air-filter.

Proceed at your own risk. I'm not saying this is the best way, it was just the way I did it. I'm not responsible for you breaking your scooter.


You will need:
Metric wrenches or sockets
1 Small hose clamp
1 Set of plastic hose connectors
1 set of vacuum plugs
Zip-Ties
New Foam Paint Brush (to make the cover for the evap-hose [c] inlet on the carburettor).
Scissors


Evap Removal



Diagram of LX150 Anti-EVAP System

The orange letters (A,B,C,D) are used in my photos to identify hoses, and to give the reader a point of reference.

*Note. On my 2007 LX150, The Vacuum Fuel Tap (#6) does not connect to hose A as the above diagram shows.

Instead, the Manifold Hose (Connecting the front of the carburetor to the manifold) has two nipples on it.

1 Hose connected to the Cannister (#5) via the Safety Valve (#4).
1 Hose, connected to the Vacuum Fuel Tap (#6)


To remove any hoses or components from hoses (With the exception of Hose C from the Carbuerator [#1]) you will have to remove the metal clamps from the hoses. To remove the clamps:

1. Put a small flathead screwdriver under the end of the clamp
2. Gently hit the end of screwdriver with a hammer
3. Twist the screwdriver to pop open the clamps



Remove the pet carrier.



Remove the two bolts that hold the Canister (#5). * Ensure there are no other clamps or ties holding the canister or the attached hoses.



Slide canister down and carefully move into engine compartment. *Be careful not to disconnect any hoses while moving the canister.



Remove hose A from canister
Remove hose B from canister
The canister can now be discarded or saved for future use.



Remove the two bolts holding the Roll-Over Valve (#3) in place.



Move Roll-Over Valve down, and into engine compartment.
Disconnect hose B from the Roll-Over Valve.



Carefully pull hose B out of engine compartment and store for later steps.



Disconnect hose C from Carburetor (#1). *This hose should pull straight out.
Save hose C for later use.



Disconnect Hose D from the Roll-Over Valve.
Disconnect Hose A from the Manifold Hose.
Hose A (with the Safety Valve (# 4) on it) can now be discarded or saved for future use.



I used a foam brush to make a filter for the hole on the Carburetor where I removed hose C from. *I saw this filter idea on modernvespa.com I can't take credit for it.
Cut the brush as show.
Gently remove, being careful not to damage the new square section of foam.
Cut a 2-3 Inch section off of hose C.
Put the foam on one end of the hose you just cut, attach it with a hose clamp, or tight zip-tie.
I sprayed a touch of filter oil on my finger, and dabbed it on the foam to help protect the carburetor.



Attach the new hose/filter combo onto the carburetor where hose C was removed from.



Plug the nipple on the exhaust hose (which hose A was removed from) with a Vacuum cap.
Secure the cap with a hose clamp for added security.


Insert a connecter into the end of hose D.



Cut a long section of hose B, and attach it to hose D via the connecter.
In the event of an over-fill or a tip over, fuel will come through this hose.



Secure the newly lengthened hose D to the frame and route the hose to a safe place for gasoline to drain.
I simply followed the frame down and secured the hose with zip-ties.



Here is hose D, If I overfill my tank. Gas simply pours out onto the ground. Not my air filter.




Take a moment to enjoy your newly de-EVAP systemed engine compartment.

Thanks.
I know by looking at the many, many, many, threads discussing the leader 150 evap, that it's very common. I felt that if I was getting frustrated reading all those threads people must be tired of re-typing the same info.

Plus, I'm 2.5 hrs away from a Vespa service shop. So without all the info you people put up, I would be without a properly running scooter. I wanted to help the community out.

Anyway, Thanks for your thanks.

I had just pulled out my air filter and cleaned it, when a cheap gas pump overfilled my tank onto my air filter. Now I have to pull all that chrome off, and clean it again.

That was the last straw for my evap system.

Why?
I've had my LX 150 since Dec 2006, and the only problem I have had is the battery going dead. No cutting out, no loss of power going up or down hills (and that's all we have here outside Pittsburgh) no vapor lock no problems. I can never understand why people always want to disconnect the evap. I just don't get the whole "I don't need it around my parts" attitude. Then again I pay attention when I fill up my bike.

I don't necessarily have a "i don't need it around my parts attitude", but it is a poorly designed system, that when combined with a malfunctioning gas pump, flooded my air filter with gas.

Outstanding!!!
Your instructions are so easy to follow even I did it in an hour.

In Calif. there is pending legislation to emission check every 2 years all motorcycles over 200cc. This makes it perfect for an LX 150. This legislation appears every few years so maybe someday you may need those parts if you alter a larger bike..

Do you think this is pretty much the same as on the 2005 ET4?? I'm hoping since I would like to do something like this over the weekend.

I would think it is almost exactly the same. The location of a few bits might be different, but for the most part it should be the same.

The lx and et4 both have the leader 150 engine. I'm pretty sure once you get in there everything will be almost exactly the same. Maybe a different color tube, or as the other poster said, a bolt in a slightly different spot.

Nice write up.

I left to components on the scoot and just disconnected the two main hoses. In part because I am lazy, and if someone wants to hook it back up in the future, it will be easy.

My first modern 150 had no troubles with the evap. The second scoot's evap has been annoying from day one. Guess I was luck the first time.

Re: LX150 Complete EVAP System Removal
Quick question - did you remove your roll-over valve? It appears so, but I didn't see that verbiage stated in your description.

Cheers,
ChimChim

Btw, I just removed the EVAP hose (C) and plugged the hose with a vacuum cap. I also attached a 3/16" ID fuel line to the carb and used your filter idea. Also, my 2009 LX 150 EVAP struture is very different than yours. My wife's ET4 mirrors your set-up.

Thanks for the great effort
That took a lot of time and effort to give us such great info on the evap problem - it printed out and added to my file.
Many thanks for the effort...I now feel safe to solve the problem should it arise.

Yes, I took the roll-over valve off. I wasn't sure of it's condition, and It was only causing worry that it might fault and cause a pressure build-up in the tank.

If I knew it was like new, I would have left the valve in place.


Sorry for taking so long to get back to you!

Took evap out a year ago
Been running awesome, just curious on what the maintenance is on the paint brush filter. I dabbed a little air filter oil on it about a year ago when I took out evap.

Maybe this is a stupid question, but is this mod needed on the new fuel injected vespas? What happens to gas overflow if the tank is filled too high on a 2013 LX150?

Not needed. Doesn't stop people from doing it though.

Recommendation: until you have an issue (and you won't) leave it alone.

Will probably do this mod on the '08 LX150 my wife just bought, but I have a question (technically 2). In the original post, the poster calls for:

1 set of vacuum plugs
Where does one get these? Do they come in different sizes, etc? Just want to make sure I have the right items at hand.

Auto parts.

Yeah, different sizes, take the hose from fitting you want to plug to match.

Don't need the hose connector. And recommend leaving rollover valve in place. In event of crash steel body = sparks. Adding a fuel spill might not be pretty.

Then how would you lengthen "hose D" in order to route it down to the bottom of the frame?

Hmm, these instructions have everything removed from that valve, so... I'm not sure how to adjust the instructions to leave the valve. Heh.

Your instructions are so easy to follow even I did it in an hour.

In Calif. there is pending legislation to emission check every 2 years all motorcycles over 200cc. This makes it perfect for an LX 150. This legislation appears every few years so maybe someday you may need those parts if you alter a larger bike..
I'm really glad that you found it useful. Thanks for your feedback! It's greatly appreciated.
Was this moved over to the wiki? I can't see the pictures on original post.

I can see the pictures correctly. Do you still can't see them?

Thank you for this post!
I just bought my 2001 Vespa ET4 150 this spring. It had less than 4k miles, and it was in great shape! Things were running well for my first several hundred miles until I started experiencing the "bogging down" at starts from red lights, etc. Also began to feel it even without starting out from a stop... to the point I had to pull over a couple times to let the engine work itself out.

I took it to a local scooter shop. They were very friendly, but they ultimately didn't know about the EVAP situation.

Thankfully, I found a YouTube video (I think about carburetor cleaning) mentioning "the EVAP mod..." which led me here. This tutorial, along with a much more stripped-down YouTube version, helped me remove the EVAP system in just under an hour. And, now... purrs like a kitten! Problem completely resolved.

A couple things I did differently than the above:
- I didn't take the vacuum hose completely off, but rather it cut it to about 3 inches. I then screwed in a large bolt into the hose to cap it. Just something I had lying around. I may buy a vacuum cap one day, but this works fine.
- I didn't have a foam brush, so I used whatever was around to cover the carburetor hose. In this case, my daughter had some thin foam "pre wrap" for gymnastics, and I used about 8 layers of this. Anything porous would work. (Also, I just cut short the hose that was originally connected... No need to buy a new hose.)
- Finally, I didn't have hose connector to extend the gas overflow tube. so I didn't extend it to the bottom of the frame. It's just tucked inside the plastic side cover. I may try to re-purpose the three-way connector to do this.

So... thanks again for original post. Fixed my engine issue. The whole project took less than an hour, and I didn't have to buy a single thing.
