If you really want learn properly then go to one of the wheelie schools. I did the one run by Andy Burnet, there's a bit of a write-up here:

I find it easier to control a wheelie on the duke, I imagine because of the better torque than a 4.
First thing tho... make sure you've learned to ride the bike properly first - I say that not knowing how much riding you've done in your 16 months! IMHO you really have to be 'at one' with your bike in order to be able to relax during your mono-wheeling... if you don't relax then you'll be crap!
Lots of people will have different ideas about how to do it properly so I'll not preach my version to you, just go to one of the schools and have some fun being taught by the pro's.
