GREAT VIDEO and I got bit by same problem on a Roketa 250C I just bought a month ago on my rear tire valve stem. I bought @ Auto Zone both the TR413 0.453 1 1/4 inch valve stem and the TR415 0.625 replacement valve stems.

The 0.453 would not seat, you could pull and pull and it would not snap in place on the rim, seemed to small. The 0.625 was to big and would not pull thru the hole in the rim. Is there an in between size valve stem or am I doing something wrong??? Is there a diff size?

@Hammered30 I'm not exactly familiar with the Roketa rims, but a standard automotive size is the one you need, It won't be real easy to pull it in and you'll have to give it some effort. try a little soap like DAWN on it to make it easier to pull, you will need a wrench to snap it in or a valve stem puller tool

normally the factory ones can hold untill the next tire, so you basically do it with the new tire at once. So this is useless. I repair chinese scooters for a living.

@barthoedemaker You may want to ask the people below , "How useless." this video is. All personal experiences may vary for sure. Bottom line- The angle valve stems on the Chinese bikes are made of natural rubber (cheap) and not a synthetic composite which is sturdier, and they'll fail. I build (PDI) these bikes and I change them out before I give to a customer. 15 minutes is worth it and if you do in fact repair them, then why not offer the service. It is a safety issue -Period. Just my opinion

Thanks! Great video! I deeply appreciate all of you who take the time to create the how-to help!

[lansdrymanvideos]

@DougMathers Thank You and out of all the videos we put online; This is one that can save your life-- no joke. Every Chinese scooter or at least 90% of them, will have this issue and a blow out at ANY speed on a two wheeler is no fun.

Where can i get those stems for à chinese scooter?

[ppilot35]

To lansdrymanvideos, you are dead wrong. My valve was cracked, leaking and pulled apart when I tugged on it to remove it. I have a 2008 scooter and the tires still have a lot of life to them....

[ppilot35]

Thanks for posting this. I had one of the cheap new stems start to leak through the cracking. I was getting ready to pull the back wheel to change it when I saw your video. It was much easier and just as effective. This is a great service to other scooter owners.

[barthoedemaker]

@lansdrymanvideos Okay your opinion. My opinion is it will hold untill the next tire easily.

[barthoedemaker]

@lansdrymanvideos Okay, if that's your opinion. My opinion is that it can hold untill the next tire, the new tyre/rim from factory does not leak, so there's no need to touch the valve stem. Never had problems with it. And I'm mostly the only company that's working on chinese scooters here in the netherlands... bartsscooterservice.nl
