Dumb question? Maybe. By bobf (Read 1,184 times)

This is a problem on my scooter, just wonder if some reason for the actions. Maybe a dumb question but I will ask it anyway.

MC-54-250 YY250T

On both the front and rear wheels the inflation stem is pointed to the brake disc side of the wheel. This makes it harder to fit the air hose or gage. Is there any reason for this? If not then when ever I must take the tire off I could rotate it to the free side of the wheels.

My daughter was visiting last week and she said hers, she has a 50cc, was the same way and it was difficult because of the brakes and brake cylinders. That was why I decided to ask.

It seems like dumb luck to me to have them that way.

You can swing them over to the other side for easy fill up.

Quick response. Thanks.

Swing them over? Aren't they captured somehow? Or is it just the air pressure. If air pressure I can then let the pressure down, rotate the stems, inflate. Is this correct?

They usually have a grove that fits around the hole where they come through. Let the air out and then wet it a little around the rubber to make it a little slippery and turn them.

I would let the pressure out, spray some WD-40 or soapy water on the stem and work it a bit until it comes loose then spin it. Be careful though, because if there is any dry rot on the rubber, you could snap them right off.

Use Soapy water rather than WD-40 , Soapy Water dries up nice around rubber, WD-40 leaves an oil on the surface after the other stuff evaporates.

If you have the brass valve stems as shown in the following tutorial, I would replace them as soon as possible. The strain of trying to twist them around may weaken them. They are not known to be reliable and are usually replaced when doing a PDI.

Here is where I bought my replacements:

Though you want to be very careful turning them in the rim. Had a heck of a time last year with mine because the China rims had sharp bur in the hole Kept cutting my Valve stems Ruined 2 tires because of Valve stem leaks. finally ended up going with Small metal Valve stems.

Thanks to all. I guess valve stems can be a problem. So before I try any twisting I will make sure there is a source for a replacement close to home. Several motor cycle shops around so I expect they might have some valve stems around. No Chinese scooter shops for several hours of driving but it sounds like the valve stems are pretty much standard.

By fall I may be living within 30 miles of three Chinese scooter shops. Maybe then I won't get hassled for not buying a recognized brand name.
