Started on the throttle in first sitting well back in the seat against the hump, started getting used to having the front end get light then slowly getting used the front getting higher, each time with smooth reduction on the throttle knowing you can touch down gently gives great confidence.(cover the back brake just in case)
from there it was bring her up until you run out of space or acceleration.
Got used to a bit of height from the front wheel so moved to clutching it under mild acceleration at about 5 or 6 grand in one fluid motion (or as close an approximation to one as you can) pull in the clutch give some welly then open the clutch hey presto your front wheels up.
You don't need a full clutch one finger'll do and it took me a while to get used to opening it up.
I'm by no means an expert and haven't yet found the balance point nor can I do slow wheelies using the rear brake but by doing this over a week or two it gave me the confidence to pop them on demand (even done a few on the blackbird) with a modicum of smoothness that can sometimes look like I know what I'm doing
