Piece of **** mate...
The best way to learn to wheelie is to start small and get used to the feeling of the bike coming up. No big heroics and you won't come off the back.
Remember that there are two ways to put the wheel down - by letting off the throttle or by hitting the back brake. Or by running out of revs. Ok, so that's three ways. But nobody expects the Spanish Inquisition.
To get the front wheel in the air is also really easy when you know how. Listen very carefully, I shall say zis only once...
Ride along in first, about 20-30mph, around 6,000rpm or thereabouts.
Now in one swift movement you need to "cough" the throttle fully open.
Give it a try ..... *cough*+twist
You should now feel the wheel start to come off the floor under power.
Don't worry, it was nowhere near as high as you thought it was and you had the back brake covered, didn't you. Didn't you?
Keep practising the cough technique and you'll soon get it higher and higher until you find the balance point. The hardest part is to get your head around bringing the wheel up in the first place.
Once you've mastered getting up, getting the distance is the next trick. You need to flutter the throttle to keep the engine on the edge of keeping the wheel in the air without accelerating too much.... but you'll get the hang of it!
Just ask Desmondo, he'll tell you what a great wheelie merchant I am
