Do you have the bike lowered and strapped? That will help with the wheelies. MOST tracks are 10.99 and faster or 12mph and you have to have full leathers. 9.99 and faster usually required a license, either IHRA or NHRA, depends on who sanctions the track. Get yourself a pair of good leathers, its for your own good.
As far as the wheelies, if you lower and strap the bike you should be able to control the wheelies decent. Use the clutch to feed the power to the ground and not the throttle. When I was stock wheelbase I could go full throttle immediately and use the clutch to control the front end.
Just because you are wheelying doesn't mean you are launching as hard as possible, it just means you gave it to much power at once. You could be launching soft but then toward the end of the clutch give it to much power and throw you into a wheelie.
I've seen so many people tell me there giving there bike all it has because they are wheelying, when in reality they are creeping off the lineand then when they get comfortable rolling, they let go of the clutch, throwing them into a wheelie.
