I have found that the fittings for putting the air into the schraeder valve (air chuck?) do not compress the valve enough to allow free flow. This is often the case when the tube/tire is very low on air pressure and not providing enough resistance to compress the valve. Putting a small pair if vice grips on the valve stem to hold it in position to keep it from sinking into the tire provides sufficient support to put pressure on the valve. If you have good air flow using different fittings, it could be bad air chucks.

Though this is somewhat off topic I blame this group
for this particular problem I m having. You all have
convinced me to change my own tires and be more self
sufficient in all aspects of keeping my 05 KLR running
right, so I m hoping you might have some answers. It s
the least you can do after all the trouble I've gone
through adjusting valves, changing oil, breaking down
tires.

In addition to the HF tire changer, I bought a Sears
electric compressor. It s a small one (15310) that s
has 1.5 HP,pressure of 125lbs, with a 3 gallon tank.
It barely inflates the tires. I thought it might be
the inflator chuck so I got another one from Kragen
Auto and it didn t help. The compressor seems to work
fine when I use the blower chuck, it goes to 120lbs,
shuts off, and will turn back on as it get down below
80 lbs. There also seems to be plenty of air pressure
with the blower, the regulator regulates the amount of
air from a weak stream to a much stronger stream, but
it takes forever to inflate a tire.
It does this on all four of my motorcycle tires (the
KLR and the HD), three with metal valves and one with
rubber. It does this with either of the inflator
chucks. The air barely goes into the tire (you can
hear a weak hiss) and sometimes it completely stops.
No amount of jiggling or adjusting the chuck has any
effect.
Have I bought an anemic compressor, am I doing
something wrong, or is it defective?
Any ideas would be appreciated.
TAI,
Mike
