air it up and spray it down with mild soap and water mixture (gallon of water with a teaspoon of dish soap mixed in). where it bubbles is your leak. spray whole tire (tread and sidewall), the edge of wheel where tire bead is seated to it and the valve stem. If there is one or 2 leaks on tread, you can plug with automotive tire plugs. More than that and you should buy a tube.
When it comes to fixing and preventing flat tires on bikes there are many options from tire liners to puncture proof tires, but I have found that tube sealants have been the best solution. Tube sealants can be used to fix existing punctures in your tires and can work as a preventative measure against future punctures. Making them a great fix and first line of defense!<br><br>They're also super easy to apply, you just inject the sealant into the tire through the air valve on the tire. The sealant works to coat the inside of the tube protecting you from any future punctures and if there is a hole in your tire it will fill and seal off the hole. A simple solution for a very big problem!
Dirt bike tires are pretty easy to change yourself and all you need is to remove the tire for the bike and have at least 3 long flat head screwdrivers that are about 18" long each. You'll save yourself a couple bucks doing it yourself and get the satisfaction of doing it yourself. But any MC shop will also do it for you at a cost unless you're buing a new tire there, then they wrap the tire change into the cost of new tire you bought. But if you decide to do it yourself, here's a couple tips. There are plenty of videos out there on how to do this so here are some quick pointers.
1) let any remaining are out of the tire.
2) for a dirtbike, loosen the rim locks. (these are on some dirtbikes and you'll know if your bike has them because there will be a bolt sticking through the rim pointing towards the center of the tire. You'll have to loosen the nut on the rim lock bolt to loosen the rim lock.)
3) with all air out of the tire and the rim locks loosened, stick your first screw driver between the lip of the rim and the tire and pull back on the screw driver.
4) When you have pulled back on the screwdriver, you'll see a gap where you can then stick the next screw driver.
5) Don't try to lift too much of the tire at the beginning. there are steel bands in the tire and you don't want to snap them or destroy the rubber that surrounds the steel bands. Because if you do mess it up too much, the steel band is made up of a bunch of steel wires, and if you snap those wires, one could come through and puncture you tube when you put it back on and fill it with air. So don't take too much tire off at one time. You'll get the hand of it.
6) With one side of the tire out you can then reach inside and pull out the tube. Fill it with a enough air to expose the lead and then you can decide to replace the tube or patch it.
7) After repairing/replacing the tube, put the tire back on in the reverse order.
8) Don't inflate the tire all the way the first time. Inflate it half way and bounce the tire to get the tube to sit right.
9) Tighten the Rim locks (if you had them)
10) inflate the tire to the proper pressure.
11) Put the tire back on.
It should have innertubes like a bicycle. Just take the wheel off and use a flathead screwdriver to pry one side of the tire off the rim. Be careful to not damage the tube when doing this. Once u have one side of the tire over the rim you can pull the tube out. You can use any bicycle tube repair kit to fix any leaks you find. Easiest way for small tubes like this is just fill a sink with water, air up the tube and put it under the water to find any leaks.
This pump is a bit strange to use. The valve in the filler head is odd in that it controls the flow of air in both direction...which is not a great design in my opinion...but it does allow for use in different filling applications. The trick is getting the pump into its different filling "modes"
For a Schrader bike valve: 1. Make sure the pump is in "tire mode" by blowing into the valve with your mouth. If you then pump the handle you should feel air filling your mouth. 2. Put the "locking lever" in the unlocked position, the unlocked
position is when the silver metal lever is parallel to the air hose, or
said another way it makes an "L" with the air outlet that goes on the
tire air filling stem. To verify this is correct, look in the air outlet and move
the lever from locked to un-locked, you will see slight
change in the diameter of the outlet. 3. Push the air filler hole over the schrader valve really hard and
make sure it is seated all the way down. Close the "locking lever"
(silver metal lever should now be perpendicular to the air house and be
in line with the air outlet... i.e. point straight out away from the
tire filler stem.
For a Presta bike valve:
1. Make sure the pump is in "tire mode" again. 2. Take off plastic caps off presta valves on bike tire. 3. Unscrew the little nut on the presta stem to allow the tire valve
to open when pressure is applied (you can test this by pushing the stem
in a little and air should escape, the nut holds the valve closed, so
it needs to be loosened). 4. Take the adapter from the locking lever (silver metal lever) on
the pump and screw it on the presta valve. The adapter is the brass
looking thing. Screw the rubber gasketed side down on the presta valve.
5. Press the air pump tire filler outlet onto the adapter.
6. Close the locking lever to seal the filler head on the adapter.
7. Pump. 8. Unlock the locking lever and pull it off quickly.
9. Unscrew the presta adapter and screw down the presta valve nut but just finger tight.
10. Screw on the plastic cover cap for the presta valve.
To Fill a Ball:
1. Twist the ball pin filler out by rotating the gray plastic tab
around until the ball pin filler is pointing straight out (in-line with
the air hose).
2. Make sure the pump is in "Ball mode" by again blowing into the filler. Sometimes shaking the filler valve really hard is necessary. 3. Put the filler pin into a ball.
HiTry this1. Let app. 50% air out2. Get a firm grip of the outer tube between your thumb and forefinger.3. Hold this grip while turning the wheel and slide the tube between your firm grip 4. This way the inner tube will be forced equally inside the tire5. Check if the inner tube is stuck between the tire and the rim, if so push it inside6. Now you can fill it with air and check again If this doesn't do the trick, it might be the rim or spokes, or a "bump/uneven" tire
Your tire tubes may have been replaced with urethane foam inserts - these give a comfortable ride like air-filled tires but cannot go flat - would explain why you don't see a fill valve - these inserts fit inside the regular tire carcass.
If they are worn out, you'll need to replace them, process is same as replacing a tube.
Basically check the condition of the tires, if they look dry and cracked it is better to replace them, The gray tube that is sticking out is the inner tube which holds the air for the tire. If that looks good just fill it up with air to the recommended air pressure on the side of the tire and put some light oil on the chain and the bike will be road ready. If after a few days your tires lose air again, it would be better to replace the inner tubes.
Your bike tube has Presta style valves. Automotive style valves are known a schraders. To inflate the tube, you will need either an adapter, presta to schrader or a hand pump that has a head for presta valves. Any bike shop will have one for sale. To fill the presta valve style, remove the black cap(if it is there) You will see little stem with a small knurled nut. Screw the nut all the way up until it stops. Put the pump head over the stem, making sure it is pushed down. Flip up the lever on the pump head, fill to desired pressure 100 to 120psi...yes, that much pressure, it's a road bike. Flip the lever on the pump head down and remove it from the stem. The PSST you will hear is the air from the line on the pump...not the tire. Screws the knurled nut down and replace the black cap. If you do not srew the little nut down and push on the stem you will let the air out of the tire. If you need more help, you can email me @ email@example.com and I will send you pictures of the process, or the staff at your local bike shop should be able to show you how.
The tyre and inner tube can be removed in the same way as a standard bicycle tyre, you can google how to remove a tyre to get some more advise.
Once you have removed the inner tube, place it in a bowl of water and try to inflate it with the pump. If you see any bubbles escaping from the tube, you have a puncture and will need to repair, again, additional advise can be found online or talk with your local bike shop for direct advise on how to do this.
If you see no bubbles you need to check that air is not escaping from the pump, if its broken then it will just vent the air as soon as you put it in.
