I always use a GPS app to check the altitude. The higher you get from sea level the thinner the air will be.

Also.......
dont forget to change your air as it can go off.
Air should be changed about the same time as your oils.

Air will also go off ( or flat ) quickly if you dont ride your bike often enough.
By daily riding the molecules within the air move around and maintain their shape.

If left for extended periods, the molecules fall to the bottom of the tube and flatten under the weight of the above molecules helped by gravity.

This is what gives the tyre the appearance of being 'flat' at the bottom.

I'm posting a wheel and tyre, should I deflate or inflate it, will it be heavier inflated?

I' m going to wait until I can get some cheap on eBay!

I heard using Genuine HD air will give you a 5-10 increase in Horsepower? Is this true?

Yes, at least 10 hp. But only if is it used for the motor..

Much rather use HD air than Nike Air
That other stuff is crap . Could never jump !

Air? I used to snort heaps of this stuff.

But I am an  older wiser family man now.

I rarely inhale at all.

 

fuck gotta get me some i need 10hp more in my girl

but can ya go straight to the harley workshop and get it ya dont have to go through the fuck stick salesman like i talked
to the other day do ya

Whilst there's no doubt genuine HD air adds both HP and style, I found when using it, my bike tended to veer over to the right hand side of the road.

I realised that the cans I was getting from the states were for domestic use only, so be sure to use the stuff made for the international market, but if you already have a stockpile of the domestic version, turn the can round the other way when filling....Not perfect, but it helps.

so iv herd ya can inhale this air with no after effects is this true
cause i rekon this would be invaluble in my job
also can you get it in 200 ltr drums nd is it cheaper this way we could all chip in and have our own containers to fill up

WTF why do you need HD Autorised Air, I couldnt find any of that stuff so I now run Solid tyres on the Fatboy Lo

Michelin Airless motorcycle tires (coppied from http://thekneeslider.com/michelin-airless-motorcycle-tires/ 

[Michelin Airless motorcycle tire] Michelin has been working on their Tweel for some time now which is a tire and wheel (“tweel”, get it?) technology that needs no air. They also have an airless tire that mounts on a separate wheel but uses plastic bands for the sides in place of the normal sidewall. You get the flex characteristics of a normal sidewall tire without any air required. Although I had heard of developments for motorcycles, I had not seen any photos. Motoblog.it has been at the Milan show and shot these photos of the Michelin airless motorcycle tire. It doesn’t look quite as radically different as the Tweel except for the fact you’re exposing the inner bands, pretty radical in its own right.

 

I bought a Authorised Harley Davidson Hand pump from the states.
I did'nt use Paypal and it took ages to get here, was getting really worried.
Harley seem to be very slow on orders and I emailed and rang and nobody got back to me.
It arrived the other day thank Harley, (Oops, God). It has a Molecular Harley Davidson Air Converter built in and as you pull up, the Air going in is Converted to Prime Harley Air and when you push down, that good shit is going right on in there.
Best purchase I've ever made. Makes me feel like I'm on drugs when I'm riding.
Far Out Man.
