my friend has a 93 cbr900rr with a 190 rear tire and when ever he brings it up in 2nd around 60mph in a power wheelie (since he hasnt learned to clutch it yet) and he is seating and not doing a standup wheelie...once he reaches the balance point the bike wants to wobble and he has to put it down....we made sure the rear wheel was straight and it is...should we adjust tire pressure??...what causes this?

 

lower the tire pressure.. some time if the tire pressure is over 18-20 psi and the tire isn't all that great it will wobble on you.. see how he is sitting on the bike when it goes up.. But in all he should try to clutch the bike up. 900's are easier to handle when you clutch it up at least for me..
