Question about Blackburn Mountain Air Mountain Bike Pump 4 Bicycle

How do I use a Blackburn Mountain air pump?

Hi, when I am inflating a tyre with the pump, what position should the "thumb guard (is that what it is?) be in? Should it be in the stowed position or the extended position to lock onto the valve stem?

Thanks in anticipation.

Dear Doug, to lock a hand pump onto the valve stem: 1.depending on valve type-loosen the valve lock for presta, twist off valve cap for schrader. 2.unlock the pumping handle from the pump so that you can actually "pump" the pump... 3. put the pump head on the valve of the tire, then pull up on the thumb tightening lever. This should squeeze toghether the internal rubber gasket of the pump, and lock on to your valve. 4. Begin pumping. 5. when desired pressure has been reached, push down on the thumb lever to unlock the pump. Remove it. Good Luck Fellow bicyclist!

How do I adjust the front brakes?

Hi, you will have to release the cable at the brake it should expand as you release the nut that tightens on the cable to hold it in place. You can also try putting the wheel in place with the tyre deflated and squeeze the tyre so that it goes between the brake blocks. Then once in place inflate the tyre back to required pressure.

I recently modified my dream machine the original pulsar150,by adding alloys and wide tyres both front and rear,so obviously the pick up will decrease,so i want to know that will there be any load on the...

It seems to me that the wide tires, if properly inflated, would not adversely or significantly cause an increased load to the engine, unless they were underinflated. I would just look for clearance issues on the fork and other parts of the frame and mud guards.

In the 1980s, when all terrain bicycles were introduced with 'fat' tires, increased traction on roads compared to their skinny tire race bike counterparts was enjoyed by the masses (Mountain bikes vs. racing bikes).

I think that on a motorcycles, the same would apply.

I don't think the K&N filter would significantly increase pickup, despite advertising to the opposite. Just use standard air filters.

Good luck on modifying your bike to your 'dream machine.'

I don't understand the way the lever works when you place the pump on the tire valve to inflate more air. Is it supposed to stay in the down position or the straight up position to lock it on the valve...

Before putting the pump on the valve turn the attachment so you can observe inside it. Move the lever back and forth. Observe at what position the lever causes the fitting to constrict and hold on to the valve. That is the position it should be in when you attach to the valve. I'm not certain but I think you will find that the fitting is able to be used for both presta and schrader valves without adjustment. Just put it on and fasten with the lever. The seal is then established.

How do I pump a presta valve with the Blackburn Mountain Air Bike Pump 4 Bicycle

They should be designed to fit both styles of valve, but you need to reverse the seal.
you should be able to unscrew the end, remove the sealing rubber and a plastic fitting that pushes on the valve, replace them the opposite way around ,and they will fit the presta.

Does the front shocks on a 1982 1100 GS take air pressure. If so how much. The exhaust pipes are hitting my front fender now when I stop hard or go over bumps.

if there are air valves, those early bike sometimes needed air, about 5psi, do not use a compresor, use a small hand pump, or proper low pressure inflator. A standard tyre inflater will blow the seals.
The guard should not hit no matter what the pressure, check the exhaust is the correct one for the bike,check for a bent frame or forks

Hi, I am having great problems getting the bead of the tyre onto the bead grove on the rim. The majority of the tyre goes on ok but a small section on each side won't go on which causes the tyre not to be...

Using a technique for setting the bead on tubeless tires, i have had a little success, but some wheels are a real pain to set beads on. Anyway, the technique is to get the tube into the tire (which is ready to be seated) and inflate it just a little bit. Don't screw the collar nut onto the valve stem but leave it off for now. Now pinch together the beads of the tire and get them to sink under the tube and into the groove that runs in the middle of the rim. When the beads are down in there, then pump away and seriously go after it; the faster you can get air in there the better. Over inflate, but not more than you feel comfortable with: i have gone as far as 20psi over recommended pressure. The last ditch effort, if all else fails, is rolling the bead into place manually with your thumbs and some elbow grease.
