I'm not a wheelie pro. I can't even ride one. But I have read alot and learned a few things that I will be starting soon to do standing wheelie's on my Busa.
1. Learn to ride with left hand with 2 fingers on handle, 2 fingers on clutch. This gives you better control of handle bars while clutching and allows you to pull up if/when need be.
2. It's heavy, so sit back in the seat a bit [standing might be different]
3. Three types I know of are clutch pop, compression bounce, and throttle:
Clutch: as mentioned above, rev up and drop the clutch. start at lower rpms til you find what works for you. These are kinda violent and scarey sometimes so start small. Busa has loads of power so don't over do it at first. Rolling in second gear about 10-20 is fine for this lower speed pop up
Compression bounce: in second [or whatever gear you choose] roll OFF throttle quickly, completely causing nose to dive, and while it's bounce back 1/5 of a second later, roll on throttle hard and it will use the bouce to come up easier.
Throttle: many modern bikes [heavey busa included] have enough power to simple gun the throttle and come up. I've done this in 2nd and 3rd gears so far on busa. one was around 80 when I dropped in 3rd and gunned it, up it came.
I'm still pondering the return to Earth part of it, cuz right now I come down HARD. Maybe someon has tips for me there. Stunt videos come down hard too so I don't feel so bad, but it has to be possible to land softly. I WILL figure it out.
You can go thru gears on a wheelie and even steer with some leaning. I guess that's the advanced class. Obviously, it's about balance - you and bike so your position is critial to find what works. Other things, I've seen, read, heard is stopping the wheelie... so far I just roll off the throttle, but I haven't gone for than 45 degrees for 2-3 seconds [I suck]. I've read to stop from going over or to even the rise out to tap LIGHTLKY the REAR break. Haven't tried it yet but makes sense. Another reason to understand or learn wheelies is they can happen by accident and *I* BELIEVE it's best to know how to control that WHEN it does happen. Pretty unlikely you will ACCIDENTLY do a stoppie, or fall off the back and hold on to the seat handle, or accidently find your self standing on the tank, but wheelies DO happen. Learn a little, ride safer a LOT.
Like I said, I'm still learning, no expert at all but hope that helped. Don't know your level so I hope it wasn't too dumbed down or something. My sources were many, many different cycle mags - they have these little tidbits sometimes "How to" type stuff, some guys that went to racing school and were okay wheeliing, a year of random experiments. It's not a goal in my life to wheelie but I do think it's good to know, so it's been very slow going. Hopefully other guys here will share there tips. Reguardless of moral opinions.
Keep in mind the law: in Iowa riding one wheel is "Failure to control the vehicle" [huh?? it's superior control getting me there] and wins you the coveted GREEN SLIP PRIZE
