Weeman, stock gearing? In that case, get rolling about 5mph, make sure you're straight front to back and top to bottom. Pull the clutch in and hold the tach at about 7K-ish (no brakes), and drop the clutch. Get a feel.
Do it again with the tach at 9K-ish.
Then go to 10mph and drop it at 12K.
This will help you build a frame of reference of how quickly and far the front comes up...
As X said, make sure it's in a parking lot or deserted road. Maybe find some local stunters in your area?
This BTW is one reason I love this group so much! Some people would just say wheelies are bad, this and that and such, but this group is very realistic... It's gonna happen, and we are gonna try things, just make it as safe as possible, no?
