One of the things I want to do is put an air horn on my bike. This got me thinking about using it as a compressor to air up tires or air beds, etc. All I really need to do is put a valve in the air supply line to divert the air to a quick coupler. A length of air hose with another coupler, a tire chuck & blow gun & I'll be set. Crank the bike, switch the valve, push the horn button & you're set. And yes, I will wire it with fuses & a relay. And if the comp. that came with the horns isn't powerful enough, I'll use a small Slime comp. I found at O'Reilly's.
I'm also going to put a switch on the back of the headlight to switch between my freeway blaster & the air horn.
So, what do you think. I can easily change my plan if y'all come up with something better.
