I watched a video and the guy removed the emissions pair system from a 50cc gy6 engine. Theres a "nozzle" that a hose used to connect to. The video shows the guy putting a rubber "cap" over the fitting and securing it with a zip tie.
Whats a good solution to my problem?
*i plan on using some thin sheet metal for the other hole. I dont have access to a welder.

So what's the problem? You don't want to use the rubber cap with ziptie?

If I read you correct this is the metal tube coming from the Cylinder Head?
If so you can purchase a block off plate or I suppose can do what you saw in the video.
Its hot down there I dunno if I would use a rubber nipple and zip tie.
NCY had some on Backorder when I need one so I just made my own block off plate.

i always use a thin piece of sheet metal (steel) or make a block off plate from some thicker steel... never had a problem...just based on what i feeling like at that moment.

Ditto that, Did the same. simple easy to do with little more than hand tools. Then the Backordered NCY Plate came in the next day. go figure huh? |

So what's the problem? You don't want to use the rubber cap with ziptie? [Three posters with responses "explaining" what ive already addressed in my first post, that ive got suitable material for the valve cover! Brilliant. I should of been more clear. I dont know where to source this rubber cap or that it is made of rubber. What has everyone else used to cover the small fitting? Not the valve cover hole that is left! What types of temps will the fitting recieve? What actually goes through the hoses? What does the pair system do? |

catch up... we all pull the complete system off. no freaking rubber plug cause the system is pulled all the way off back to the fuel tank and the intake elbow. its gone maybe an air box vacuum line hooked to the pvc, one for the carb and one for the fuel pump or fuel cutoff valve depending on what you got...and 1 fuel line, everything else is stripped off, and there is more than one style. if you got 2 nipples in the intake elbow, the thing the carb is attached to use one nipple for the carb slide, and the other for the fuel system (pump or fuel cut off) ..dont have to plug nothing, got only one, gonna have to use a splitter,
cut the metal tube off at the head and stick a piece of metal between the head and the fitting flange and its done.
just because you watched a video doesn't mean we have any idea what you or he was talking about... frankly i have done over a dozen scooters and have no idea about what you speak, there are several nipples for vaccum lines depending on where this random video guy stopped, so for plugs i typically just thread a bolt into a rubber hose that fits the nipple. the real ones are sold at auto parts stores, and called vacuum caps.
what goes thru them is air, it injects fresh air into the hot exhaust, rich with oxygen to burn off and unburnt fuel and help complete combustion

Vacumn cap helped immensely. Got a 4 pack at advanced auto fir two-fifty. Quarter inch size. |

What's the benefits to removing that system?

The real question is what's the benefit of having them. All they do is cause a mess in the airbox and foul the engine trying to burn dirty gases.

What's the benefits to removing that system? Having one less system that can cause problems. However if you are in an area that requires emission testing on scooters, you do not want to remove it, it will cause you to fail and will not be able to re-register. Again tho that is only if emissions are required for your scooter. |

Any performance gain? I know removing the same system on a car equals more power, same effect on a scooter? No emissions where I'm at.

I have removed the emissions on my scooter as well, other than having to adjust the carb, due to no longer having un-burnt fuel recycled, I have seen no improvement in how my scooter runs. May be wrong but I don't think these scooters are producing enough power for any difference to be noticeable. |

Good to know. I won't waste my time trying to take it off then. Thanks for the answer!

May be wrong but I don't think these scooters are producing enough power for any difference to be noticeable. I sort of think the opposite about these scoots. They produce so little power ,that the littlest things make a big difference. For instance , if you crouch over while riding these scoots , you gain a good 3mph or more . sometimes if I'm riding into a strong head wind I have a hard time going over 60mph , but if I crouch over I'm able to reach a much higher mph due to not only lest wind , but the ability to reach a higher rpm. Same with weight , 40 lbs on these scoots makes a noticeable difference . if you were riding a 600 cc bike , these things would not be as noticeable. Another problem is that many of us end up running these scoots all out , to the point that it just won't go any faster. These engines are not powerful enough to reach 90mph so we top them out easy , and thats why the smallest things make noticeable changes. Just like colder weather , yes it effects all vehicles , but with these scoots you may pic up a couple mph on the top end , but when it comes to a bigger cc bike , you may not notice the better performance because your usually not topping the engine out and you can hit 100+ in cold of hot weather , and if your not looking at ht rpm gauge with a microscope , you may not notice it was easier to hit 100+ mph. Now when it comes to removing all of the emissions , you can usually tell a difference , unless your not tuned properly afterwards. It may not be much , but there is usually a difference in performance. |
