EGR System - What do i take off to eliminate it? From what i hear its a couple of hoses and a canister or two?
Do you guys have any links or pics on how to remove it? My new exhaust header is coming today via fedex so i wanna get a head start on how to do this?
thank you.

If its the EGR system then it makes it easy since your going to replace the exhaust which will not have the valve on it.
So you go to the canister and it will have a VACUUM hose coming from either straight from the intake manifold or a "T" or a "Y" connector, PLUG the VACUUM at it's ORIGIN. Then you will see a hose going to either the AIR BOX or AIR TUBING going to the carb, take the hose off there and plug it THERE then take the whole canister with the hoses off DONE.

hey alleyoop
i made a video, stuck again, not too sure what i supposed to take off? There are so many hoses
So far i took off the hose that connects with the EGR valve on the exhaust, the other end is connected to a Tee as u can see on my video. thanks for your expertise.

OK. what you have is the Vacuum controlling several things and are connected to ONE VACUUM supply coming from the INTAKE MANIFOLD. NOT A PROBLEM. 1. Take the hose coming off the TANK that goes to that little cylinder disconnect it from the little canister there and put a fuel filter on the end of that hose(THAT IS YOUR GAS TANK VENT SYSTEM) and zip tie it so it vents. 2. Take the hose that goes to the AIR FILTER TUBING take it off there and plug the CONNECTOR on the AIR TUBING. 3. Take the VACUUM HOSE going to the connector that THEN SPLITS ALL OVER the place and disconnect it from the connecter and PLUG the VACUUM hose. NOW YOU SHOULD be able to take the big canister off the Valve on the side and the little canister off. You should then have ONLY TWO VACUMM hoses connected: 1. One Vacuum hose going to the PETCOCK to feed the carb fuel. 2. One Vacuum hose going to the RIGHT side of the Carb to the ACV valve. and that is it. Best setup is something like mine One Vacuum hose coming from the INTAKE MANIFOLD to a "T" or a "Y". Then From the "T" or "Y" one hose goes to the PETCOCK and one hose goes to the ACV valve on the right side of your carb and that is it. Alleyoop  |

When I removed my EGR system on a gy6 50cc, power & top speed was cut in half. Obviously the system affects the mixture, and I've been working my way through a range of jets without much success. It would be helpful to hear from anyone about how they sorted this out.

Keep in mind that all the aftermarket exhausts have no EGR valve on the exhaust so many people will be with the issue of removing the emissions system (egr or pair systems) u are only the third person to say this versus 20 people have said the opposite as in: better power, less clutter, lighter weight, easier to work on the engine, less hoses failing etc...  |

Well on some it may effect the mixture setting BUT NOT IN HALF, unless of course the carbs fuel mixture was way off to being with. Most folks do not know how to adjust their carbs Fuel Ratio Mixture correctly to get the most out of the motor. If you know what the EGR system is doing you would understand why it may effect it when taken off. On some it may improve the mixture and on some it may degrade the mixture it all depends on how the carb mixture setting was set when the EGR was on and working.
What the EGR is doing is sending the UNBURNED fumes back into the intake to be burned again, that is why you see a hose going to the INTAKE TUBING connected to the AIR side of the carb. So if it was running lean with the unburned fumes, taking it off it will now run even leaner, if it was running rich with the unburned fumes now it may improve the mixture and no longer running that rich.

Cleaner engine bay was the plan, which worked out OK. But I didn't expect the power & speed to be cut in half. Attached is the valve cover showing the EGR tube which picks up the exhaust gas at the exhaust port and cools the gas before it's routed to the intake manifold. There's no connection to the exhaust pipe, only the exhaust port. PS: Sorry! This new ProBoards system is also defeating me! Can't see how to attach the photo. |

If your talking about the chrome pipe attached to the valve cover that is NOT an EGR system that is a PAIR system. All that does is suck in fresh air into the Exhaust port. ON that one you have to block off the Hole in the head where the chrome pipe attached to. Alleyoop This is a PAIR system.  This is a EGR system.  |

Yes, that's what I have, blocked off as you describe. Too bad I can't figure out how to attach images in this new system, then I wouldn't make so much work for you! A photo is worth 1000 words. How did you attach the photos?

Use this it is free and easy to use: When you took it off did you also plug up the VACUUM to the canister or at it's origin? Alleyoop 1. Click on this link: tinypic.com/index.php2.

ive noticed that on every EGR thread ive been to while doing my research, people always confuse the EGR system with the PAIR system, just saying
