I've used the leaf blower, shop Vac and air compressor (or air tank).
I made a special nozzle for my compressor using old pipe fittings and a foam filter. Works good for tight places.
But I usually just ride the bike a few miles, come back and wipe it down with pledge and a microfiber cloth.

 

I've used an electric leaf blower on all my bikes and it works fine. Can dry my Ultra in 10 minutes.

 

Thanks for all the input, guys! Guess I'll buy the leaf blower.

 

Same here. I use a Rigid 6.5hp shop vac with a detachable blower. It's hand held and very compact and perfect for drying off a bike. The compressed air is not a good idea; moisture can collect in the tank, along with tiny bits of rust.

 

Air compressor in the shop at work.

 

Electric leaf blower from a yard sale. $2.00. Works great.

 

Another leaf blower user. Sure, an air compressor will work great, but you gotta be careful. If you have it turned up high and get a nozzle too close, you can blow the paint right off, especially if you hit the edge of a chip.

 

+1 on leaf blower, my sears 200 mph backpack gets me dry in like 5 minutes, and no water spots!

 

I use a shop vac , with the hose on the outlet fitting. At least I know I am blowing clean air at the bike. Works just fine, saves a lot of drying with a shammy...

 

Sears has been running bi-monthly sales on blowers.. $19 for electric 150 mph out the nozzle. Better than sucking the fumes from my old 2 stroke blower and much quieter.
