Popping mono's (wheelies)

Hey guys..... Just thought I should ask for some advice/pointers here... But I have started practicing popping mono's on my 250 ninja.... It's a pretty violent 1st gear pick-up..... I was wondering first of all what I should watch out for in terms of damaging the bike.... I.e. Blowing fork seals... But more specifically what things I will be able to notice before they completely shut themselves... Lol...
Cheers guys (and girls)
