wheelie

I don't know if this is the right place to post this, but I've looked at tons of wheelie vids on youtube and I can't seem to lift the front end up at all...I have a 2013 fz6r. Do any of you have any tips. Thank you

Ok so im going to be going to a -2, +3 config on my front and rear sprockets what kind of loss in top speed can i expect from such big change in gearing , the reason im doing it is to gain torque for better wheelies and faster acceleration any tips/ suggestions
